The modules are plug-and-play for easy installation and site maintenance. 2. The base unit has capacity for four modules.3. Each module has DC input and DC output for three Remote Radio Units (RRU), for a total capacity of 12 RRU sectorsper PowerShift base unit.4.Each module unit is also provided with diagnostic indicators, explained in section 12.Section 1: PowerShift ™ V1 System ComponentsThe PowerShift V1 System Consists of two components: the Base Unit and Capacitive Jumpers.Rack Part Number: PS-R-1Module Part Number: PS-1-73Note: The PowerShift base unit will not operate without the corresponding Capacitive Jumper. Each modulerequires three Capacitive Jumpers (oneper circuit)1 Per circuit; 3 circuits per module2Input/output voltage and current range are guaranteed values, typical operating values will exceed these by about 10%; examples:Typical input cutoff (minimum) voltage: 42V x 0.9 ≈ 38VTypical output maximum current: 20A x 1.1 ≈ 22A3 Turn-on voltage is higher than cut-off voltage in order to provide hysteresis protection4 Total power = power consumed by radio + power loss in trunk cable5 RRU input voltage set-point is factory programmed (not user settable). Other voltage set-point are possible, contact CommScope 6For cable lengths outside these ranges, contact CommScope for more informationThe Capacitive Jumper is a circuit at the radio input to provide the PowerShift base unit with information regarding actual line impedance. Additionally it compensates for DC inductance of the power line further reducing power loss.Section 2: Capacitive JumperGeneral SpecificationsTypePower-only Capacitive Jumper BrandHELIAX ® FiberFeed ® Conductor Gauge, singles 6-12 AWG (10 AWG typical)Conductors, quantity 2Enclosure Color Grey Jacket ColorBlackEnvironmental SpecificationsEnvironmental Space UV resistant for outdoor and/or direct burial installations Operating Temperature Maximum value based on a standard condition of 20 °C (68 °F)Safety Voltage Rating600 VDimensionsWeight 1.1 kg | 2.5 lb Diameter Over Jacket12.395 mm | 0.488 inEnclosure 304.8 mm | 12 in (length, including cable gland nuts) 76.2 mm | 3 in (width)76.2 mm | 3 in (depth)GeneralMount Tabs includedSection 3: Recommended Interconnect Power Cables(coordinate with a CommScope representative to determine popper gauge/length) ConstructionMaterials: PWRT-210-S Construction Type Conductor Material Dielectric MaterialDrain Wire MaterialFiller MaterialGround Wire Material Insulation Material, singles Jacket MaterialOuter Shield (Braid) Coverage Outer Shield (Braid) Gauge Outer Shield (Braid) Material Outer Shield (Tape) MaterialDimensionsCable WeightDiameter Over Conductor, singlesDiameter Over Dielectric Diameter Over Drain WireDiameter Over Ground Wire Diameter Over Jacket Diameter Over Shield (Braid) Jacket Thickness Electrical Specifications Conductor dc Resistance Conductor dc Resistance NoteSafety Voltage Rating Environmental Specifications Environmental Space Operating Temperature Safety Standard General Specifications ApplicationCable TypeJacket ColorConductor Gauge, singles Conductor Type, singles Conductors, quantity Construction TypeDrain Wire GaugeGround Wire Gauge Ground Wire TypeJacket Color, singles Non-armoredTinned copperPVCTinned copper PolypropyleneTinned copperPVCPVC65 %36 AWGTinned copperAluminum/Poly, nonbonded0.30 kg/m | 0.20 lb/ft3.2004 mm per 105 strand0.1260 in per 105 strand4.7244 mm | 0.1860 in1.8800 mm per 7 strand0.0740 in per 7 strand3.200 mm | 0.126 in12.395 mm | 0.488 in10.109 mm | 0.398 in1.143 mm | 0.045 in1.06 ohms/kft | 3.47 ohms/km Maximum value based on a standard condition of 20 °C (68 °F)600 VUV resistant for outdoor and/or direct burial installations-40°C to +90 °C (-40°F to+194 °F)NEC Article 336 (Type TC)IndustrialPowerBlack8 AWGStranded2Discrete power cable12 AWG10 AWGStrandedBlack | RedPWRT-210-SSection 4: General Wiring DiagramBoxSleeve/Pendant Long cable runPower-only Capacitive JumperRemotesJunction or splice box* based on the # of RRU’s on-siteSection 5: Rack InstallationDetermine the installation depth required for the base unit, attach the side flanges in the appropriate location. 3 screws are required per side.Mount the unit in a standard 19” rack near the current DC power output breaker box.Ground the unit by installing a ground wire at the base of the unit.Section 6: Wiring of the ModuleRemove 2 small screws on the back of the unit and remove the back cover to expose the terminal screws. (replace screws to keep them with the unit)The rear of the shelf is divided into 12 individual circuits each containing a DC input and a DC output. There is a positive and negative terminal strip connection for each DC input and out. The right side pair is for the DC input and the left sideRun cables from the Base Unit Output screws to the baseband Surge Protection Device / Over Voltage Protection (SPD / OVP) input if installed. Then attach the SPD / OVP outputs to the trunk cable that runs to the Remote’s.If no SPD/OVP is installed, then connect the trunk cable directly to the Base Unit Output screws.Repeat for each circuit.Re-install the back cover of the unit when complete.the expected value in micro-Farads (µF) is 1100µF +/- 25% (i.e. 825 to 1375µF). If an open or short condition is detected then there is likely a fault in the trunk cable or in the capacitive jumper.Section 8: Capacitive Jumper MountingMethod 2: Using a multi-meter, take a resistance measurement across the Base Unit Output screws. First, take a resistance measurement to confirm the circuit is open. Second, temporarily connect (short) the two conductors together at thecapacitive jumper (i.e. at the end of the capacitive jumper cable) and take a resistance measurement; the value should be less than 3 Ohms (it is dependent on the trunk cable gauge and length).Connect the other end of the capacitive jumper to the Remote Radio Unit. See section 10 for connector installation instructions.23Loosen 4 screws to remove the cover. Screws are ARE captive to the lid but can be removed if required.1Section 9: Splicing Capacitive Jumper to Power101.6 mm (4 in)6.35 mm (1/4 in)When lid is removed inspect pre-installed jumper to be sure nothing has come loose during shipping and handling.Braided ground-48VRTNRemove 101.6 mm (4 inches) of outer shielding from the power trunk cable.

If any status lights are not green, refer to the alarm information below.6. Note the following:• Cycling the input power to a circuit (off and back on) will restart the 30 second measurement interval (i.e., the module will perform a new measurement of the line resistance)• After the 30 second measurement interval is complete, the module will use the measured line resistance indefinitely;it will not attempt to re-measure the line resistance unless the input power to the circuit is cycledAlarmsThere are four LED status indicators on each PowerShift Module: 1, 2, 3 and X:1. 1, 2 and 3 represent the status of each of the three power circuits in the module.2. X represents the status of the overall module.3. Intermittent or latent failures will be indicated by the X indicator even if the individual circuits are functioning correctly.Circuit LEDs (1, 2, 3)1. Solid green LED indicates the circuit is functioning properly.2. A blinking green LED indicates the circuit is performing a line resistance measurement• This occurs every time input power is applied to the circuit (including when the input power is cycled off and back on)• The circuit LED should blink green for about 30 seconds and then change to solid green• If the LED continues to blink green after 30 seconds this indicates an alarm condition (the module is unable to measure the line resistance)Module LED (“X”)1. Solid green LED indicates the module is functioning properly.2. If the X LED is not green, but 1, 2 and/or 3 are green, the indicated circuit(s) are still functioning properly and deliveringpower, but a latent failure has occurred (e.g., a temporary over-temperature condition)See the alarm table on following page for additional information on LED status and troubleshootingThe power module is designed to shut off the output from a circuit in the event the load demand exceeds the circuit maximum output capacity of 1460W total power (radio demand + power loss in the trunk cable)Under normal circumstance an output overload should not occur; the proper design and installation of the PowerShift system ensures the maximum radio load demand and the trunk cable length do not exceed the circuit capacity.However, off-nominal events such as a short in the trunk cable or a malfunctioning radio could cause the load demand to exceed the module output capacity. In this event the module functions as follows:When circuit capacity is exceeded the module will shut off its output, the GUI appears as shown below using Circuit 1 as an example Note the following: • The GUI shows Circuit 1 has input voltage but no output voltage or current (output is shut off due to the overload condition)• The LEDs and GUI icons for Circuit 1 for “X” are yellow blinking• The GUI circuit status shows red text for “off” (no output power) and out• The alarm relay on the back of the shelf is set for a critical alarm conditionSection 12: Output Circuit Overload ProtectionModule Circuit-Overload RecoveryThe module will check the condition of the circuit about every 3-5 seconds to determine if the overload condition remains or if it has cleared; each time the circuit check is performed the applicable module circuit LED will briefly flash green and the GUI status will briefly show “okay”If the overload condition clears within 20 minutes then the module will re-enable power output of the circuitIf the overload condition has not cleared, the module will continue to keep the circuit output shut off and will continue to check the circuit condition about every 3-5 secondsAfter 20 minutes, if the circuit overload condition has not cleared, the module will latch the circuit output off and will discontinue checking the circuit condition (the applicable circuit and “X” LEDs will continue to blink yellow)Once the circuit has latched off, the user must intervene as follows to re-enable the circuit:• The circuit overload condition must be cleared• The input power to the circuit must be cycled off and back on (typically by using the DC plant circuit breaker)• The circuit will re-enable its output power, the applicable circuit LED will blink green for about 30 seconds while the line resistance is measured• After about 30 seconds:• GUI Circuit number icon and the module front panel LED are both solid green• The GUI circuit status shows “okay”• The GUI “X” icon and module LED are both solid greenModule High Temperature ProtectionT he power module is designed to protect itself from an excessive temperature (overheating) condition. Under normal operating conditions the module cooling fans provide adequate cooling for the module. However in off-nominal conditions (blockage of the module’s air intake or exhaust grill, failure of the site shelter cooling) the module will shutoff output if its internal temperature rises too high. In this event the module functions as follows:• When the internal temperature rises too high the module shuts off the output of all affected circuit(s)• There are two possible operating conditions for the module once a thermal overload has occurred: Condition 1, Critical Alarm: The high temperature condition (e.g., failure of the shelter cooling) has not beenresolved and thus the module output remains shut off. The high temperature condition must be resolved and the internal module temperature allowed to drop down below threshold before the module will re-enable its output powerCondition 2, Major Alarm: The thermal overload condition has been resolved and the module output hasre-enabled. Note that the thermal overload alarm still remains active (latched) until the user intervenes to clear the alarm• Using Circuit 1 as an example, the GUI and module LEDs will appear as shown below for the two conditions:Thermal Shutdown, Condition 1, Critical Alarm (high temperature condition is not resolved, no output power)Note the following:• The GUI shows Circuit 1 has input voltage but no output voltage or current (output is shut off due to an unresolved high temperature condition)• The GUI Circuit 1 icon and the “X” icon are both highlighted red blinking• The GUI Circuit 1 status shows “temp out-I off” indicating the circuit shutoff is due to a thermal overload• The module front panel “1” and “X” LEDs are both red blinking• The alarm relays on the back of the shelf is set for a critical alarm conditionThermal Shutdown, Condition 2, Major Alarm (high temperature condition has resolved, output power in enabled)Note the following:• The GUI shows Circuit 1 has output voltage and output currentThe GUI Circuit 1 icon shows green blinking, the “X” icon shows yellow solid•• The GUI Circuit 1 status shows “temp ” indicating there is an alarm condition on the circuit (i.e., a latched alarm for the prior thermal shutdown)• The module front panel “1” LED is green blinking, and the “X” LED is yellow solid• The alarm relays on the back of the shelf is set for a major alarm conditionModule Thermal - Overload RecoveryNote the following:• If the module is still shutdown (Condition 1, critical alarm) then the high temperature condition must first be resolved(e.g., unblock the fan, restore shelter cooling) such that the module internal temperature falls below the shutdownthreshold and the module re-enables output power (it will then be in Condition 2)• Once the module has re-enabled power (Condition 2, major alarm) the user must clear the alarm by using the GUI to click the “clear” button for each circuit that has highlighted “temp” status• The applicable circuits will change back to nominal operating condition (see below):The GUI Circuit number icon and the module front panel LED are both solid greenThe GUI circuit status shows “ok”The GUI “X” icon and module LED are both solid greenDip Switch and RJ45 jacks are present on each base unit for possible attachment to an external controller such as a GE Critical Power Standard Controller.Section 14: Dip Switch / RJ45 Jacks / Alarm RelayThe Dip switch position is factory preset for no controller with both switches down.

C | Page 9 of 14TERMINOLOGYRelative AccuracyRelative accuracy or integral nonlinearity (INL) is a measure of the maximum deviation, in least significant bits (LSBs), from an ideal line passing through the endpoints of the DAC transfer function. Figure 4 shows a typical INL vs. code plot. The ADN8810 INL is measured from 2% to 100% of the full-scale (FS) output.Differential NonlinearityDifferential nonlinearity (DNL) is the difference between the measured change and the ideal 1 LSB change between any two adjacent codes. A specified differential nonlinearity of ± 1 LSB maximum ensures monotonicity. The ADN8810 is guaranteed monotonic by design. Figure 5 shows a typical DNL vs. code plot . Offset ErrorOffset error, or zero-code error, is an interpolation of the output voltage at code 0x000 as predicted by the line formed from the output voltages at code 0x040 (2% FS) and code 0xFFF (100% FS). Ideally, the offset error is 0 V . Offset error occurs from a combination of the offset voltage of the amplifier and offset errors in the DAC. It is expressed in LSBs.Offset DriftThis is a measure of the change in offset error with a change in temperature. It is expressed in (ppm of full-scale range)/°C. Gain ErrorGain error is a measure of the span error of the DAC. It is the deviation in slope of the output transfer characteristic from ideal. The transfer characteristic is the line formed from the output voltages at code 0x040 (2% FS) and code 0xFFF (100% FS). It is expressed as a percent of the full-scale range.Compliance VoltageThe maximum output voltage from the ADN8810 is a function of output current and supply voltage. Compliance voltage defines the maximum output voltage at a given current and supply voltage to guarantee the device operates within its INL, DNL, and gain error specifications.Output Current Change vs. Output Voltage ChangeThis is a measure of the ADN8810 output impedance and is similar to a load regulation spec in voltage references. For a given code, the output current changes slightly as output voltage increases. It is measured as an absolute value in (ppm of full-scale range)/V .O U T P U T V O L T A G E03195-0-004Figure 16. Output Transfer FunctionADN8810Data SheetRev. C | Page 10 of 14FUNCTIONAL DESCRIPTIONThe ADN8810 is a single 12-bit current output digital-to-analog converter (DAC) with a 3-wire SPI interface. Up to eight devices can be independently programmed from the same SPI bus. The full-scale output current is set with two external resistors. The maximum output current can reach 300 mA. Figure 17 shows the functional block diagram of the ADN8810.03195-0-017Figure 17. Functional Blocks, Pins, and Internal ConnectionsSETTING FULL-SCALE OUTPUT CURRENTTwo external resistors set the full-scale output current from the ADN8810. These resistors are equal in value and are labeled R SN in Figure 1. Use 1% or better tolerance resistors to achieve the most accurate output current and the highest output impedance.Equation 3 shows the approximate full-scale output current. The exact output current is determined by the data register code as shown in Equation 4. The variable code is an integer from 0 to 4095, representing the full 12-bit range of the ADN8810.SNFS R I ×≈10096.4(3)+Ω××=1.0151000,1k R R Code I SN SN OUT(4)The ADN8810 is designed to operate with a 4.096 V referencevoltage connected to VREF. The output current is directly proportional to this reference voltage. To achieve the bestperformance, use a low noise precision (the ADR292, ADR392, or REF198 is recommended).POWER SUPPLIESThere are three principal supply current paths through the ADN8810: •AVDD provides power to the analog front end of the ADN8810 including the DAC. Use this supply line topower the external voltage reference. For best performance, AVDD must be low noise.•DVDD provides power for the digital circuitry. Thisincludes the serial interface logic, the SB and RESET logic inputs, and the FAULT output. Tie DVDD to the same supply line used for other digital circuitry. It is not necessary for DVDD to be low noise.•PVDD is the power pin for the output amplifier. It canoperate from as low as 3.0 V to minimize power dissipation in the ADN8810. For best performance, PVDD must be low noise.Current is returned through the following three pins: •AVSS is the return path for both AVDD and PVDD. This pin is connected to the substrate of the die as well as the slug on the bottom of the lead frame chip scale package (LFCSP). For single-supply operation, connect this pin to a low noise ground plane.•DVSS returns current from the digital circuitry powered by DVDD. Connect DVSS to the same ground line or plane used for other digital devices in the application.•DGND is the ground reference for the digital circuitry. In a single-supply application, connect DGND to DVSS.For single-supply operation, set AVDD to 5 V , set PVDD from 3.0 V to 5 V , and connect AVSS, AGND, and DGND to ground.SERIAL DATA INTERFACEThe ADN8810 uses a serial peripheral interface (SPI) with three input signals: SDI, CLK, and CS . Figure 2 shows the timing diagram for these signals.Data applied to the SDI pin is clocked into the input shift register on the rising edge of CLK. After all 16 bits of the data-word have been clocked into the input shift register, a logic high on CS loads the shift register byte into the ADN8810. If more than 16 bits of data are clocked into the shift register before CS goes high, bits are pushed out of the register in first-in first-out (FIFO) fashion.The four MSB of the data byte are checked against the address of the device. If they match, the next 12 bits of the data byte are loaded into the DAC to set the output current. The first bit (MSB) of the data byte must be a logic zero, and the following three bits must correspond to the logic levels on pins ADDR2, ADDR1, and ADDR0, respectively, for the DAC to be updated. Up to eight ADN8810 devices with unique addresses can be driven from the same serial data bus.Table 5 shows how the 16-bit DATA input word is divided into an address byte and a data byte. The first four bits in the input word correspond to the address. Note that the first bit loaded (A3) must always be zero. The remaining bits set the 12-bit data byte for the DAC output. Three example inputs are demonstrated.•Example 1: This SDI input sets the device with an address of 111 to its minimum output current, 0 A. Connecting the ADN8810 pins ADDR2, ADDR1, and ADDR0 to VDD sets this address.• Example 2: This input sets the device with an address of 000 to a current equal to half of the full-scale output. •Example 3: The ADN8810 with an address of 100 is set to full-scale output.STANDBY AND RESET MODESApplying a logic low to the SB pin deactivates the ADN8810 and puts the output into a high impedance state. The device continues to draw 1.3 mA of typical supply current in standby. When logic high is reasserted on the SB pin, the output current returns to its previous value within 6 µs.Applying logic low to RESET sets the ADN8810 data register to all zeros, bringing the output current to 0 A. When RESET is deasserted, the data register can be reloaded. Data cannot be loaded into the device while it is in standby or reset mode.POWER DISSIPATIONThe power dissipation of the ADN8810 is equal to the output current multiplied by the voltage drop from PVDD to the output.()SN OUT OUT OUT DISS R I V PVDD I P ×−−×=²(5)The power dissipated by the ADN8810 causes a temperature increase in the device. For this reason, PVDD must be as low as possible to minimize power dissipation.While in operation, the ADN8810 die temperature, also known as junction temperature, must remain below 150°C to prevent damage. The junction temperature is approximatelyDISS JA A J P T T ×θ+=(6)where:T A is the ambient temperature in °C,θJA is the thermal resistance of the package (32°C/W). •Example 4: A 300 mA full-scale output current is required to drive a laser diode within an 85°C environment. The laser diode has a 2 V drop and PVDD is 3.3 V .Using Equation 5, the power dissipation in the ADN8810 is found to be 267 mW . At T A = 85°C, this makes the junction temperature 93.5°C, which is well below the 150°C limit. Note that even with PVDD set to 5 V , the junction temperature increases to only 110°C.USING MULTIPLE ADN8810 DEVICES FOR ADDITIONAL OUTPUT CURRENTConnect multiple ADN8810 devices in parallel to increase the available output current. Each device can deliver up to 300 mA of current. To program all parallel devices simultaneously, set all device addresses to the same address byte and drive all CS , SDI, and CLK from the same serial data interface bus. The circuit in Figure 18 uses two ADN8810 devices and delivers 600 mA to the pump laser.SERIAL INTERFACE (FROM µC OR DSP)I 600mA03195-0-018Figure 18.

This is accomplished by dithering the V REF voltage input to the ADN8810. Figure 19 demonstrates one method.DITHERR203195-0-019Figure 19. Adding Dither to the Reference VoltageSet the gain of the dither by adjusting the ratio of R2 to R1. Increase C to lower the cutoff frequency of the high-pass filter created by C and R1. The cutoff frequency of Figure 19 is approximately 98 Hz.The AD8605 is recommended as a low offset, rail-to-rail input amplifier for this circuit.DRIVING COMMON-ANODE LASER DIODESThe ADN8810 can power common-anode laser diodes. These are laser diodes whose anodes are fixed to the laser module case. The module case is typically tied to either VDD or ground. For common anode to ground applications, a −5 V supply must be provided.In Figure 20, R SN sets up the diode current by the following equation:40965.16111.1096.4Code k R I SN ×Ω+×=(7)where Code is an integer value from 0 to 4095.Using the values in Figure 20, the diode current is 300.7 mA at a code value of 2045 (0x7FF), or half full-scale. This effectively provides 11-bit current control from 0 mA to 300 mA of diode current.The maximum output current of this configuration is limited by the compliance voltage at the IOUT pin of the ADN8810. The voltage at IOUT cannot exceed 1 V below PVDD, in this case, 4 V. The IOUT voltage is equal to the voltage drop across R S N plus the gate-to-source voltage of the external FET. For this reason, select a FET with a low threshold voltage.In addition, the voltage across the R SN resistor cannot exceed the voltage at the cathode of the laser diode. Given a forward laser diode voltage drop of 2 V in Figure 20, the voltage at the RSN pin (I × R SN ) cannot exceed 3 V . This sets an upper limit to the value of code in Equation 5.Although the configuration for anode-to-ground diodes is similar, the supply voltages must be shifted down to 0 V and −5 V , as shown in Figure 21. The AVDD, DVDD, and PVDD pins are connected to ground with AVSS connected to −5 V .The 4.096 V reference must also be referred to the −5 V supply voltage. The diode current is still determined by Equation 7. All logic levels must be shifted down to 0 V and −5 V levels as well. This includes RESET , CS , SCLK, SDI, SB , and all ADDR pins. Figure 22 shows a simple method to level shift a standard TTL or CMOS (0 V to 5 V) signal down using external FETs.NOTE: LEAVE FB WITH NO CONNECTION03195-0-020Figure 20.

Level Shifting TTL/CMOS LogicPCB LAYOUT RECOMMENDATIONSAlthough they can be driven from the same power supply voltage, keep DVDD and AVDD current paths separate on the printed circuit board (PCB) to maintain the highest accuracy; likewise for AVSS and DGND. Tie common potentials together at a single point located near the power regulator. This technique is known as star grounding and is shown in Figure 23. This method reduces digital crosstalk into the laser diode or load.LOGIC GROUNDRETURN03195-0-023Figure 23. Star Supply and Ground TechniqueTo improve thermal dissipation, solder the slug on the bottom of the LFCSP package be soldered to the PCB with multiple vias into a low noise ground plane. Connecting these vias to a copper area on the bottom side of the board further improves thermal dissipation.Use identical trace width and lengths for the two output sense resistors. These lengths are shown as X and Y in Figure 24. Differences in trace lengths cause differences in parasitic seriesresistance. Because the sense resistors can be as low as 1.37 Ω, small parasitic differences can lower both the output current accuracy and the output impedance. See the AN-619 Application Note for a sample layout for these traces.03195-0-024Figure 24. Use Identical Trace Lengths for Sense ResistorsSUGGESTED PAD LAYOUT FOR CP-24 PACKAGEFigure 25 shows the dimensions for the PCB pad layout for the ADN8810. The package is a 4 mm × 4 mm, 24-lead LFCSP . The metallic slug underneath the package must be soldered to a copper pad connected to AVSS, the lowest supply voltage to the ADN8810. For single-supply applications, this is ground.

The HW has the following features: • • • • • • • • • • • • GPRS and HSCSD with Edge in up to (2RX + 2TX) (MCS5), without edge also in (3RX + 1TX) (MCS6) DCT4 with AMR and 16 MIDI tones 128/16 Mbit Combo memory Amazon Active display with 64k colours Battery BL-5B Illuminated XPress on grips Pop-Port interface 5-way navigation key with select FCI rear side (C-cover) VGA Camera Vibra IHFThe RH37 BB is based on the DCT4/4.5 engine and is compatible to the Pop-Port accessories. The DCT4/4.5 engine consists basically of two ASICs. The UEMEK (Universal Energy Management IC including voltage regulators, charge control and audio circuits, audio IFH amplifier from DCT4.5) and the UPP (Universal Phone Processor including MCU, DSP and RAM from DCT4).New A4PC Template especially for UlmCopyright © Nokia Mobile Phones5 ( 64 ) CONFIDENTIAL Nokia Mobile Phones08-Apr-04 错误！错误！未知的文档属性名称1.1 Block diagramThe picture below shows the main Baseband function blocks.VVCameraRF InterfaceLCDActive TFD colourFLASH128 MbitSRAMLED drivers16 MbitSIMUEMEKUPP8MFunctional Cover IFBatteryBL-5BKeyboardKeyboard IlluminationVIBRAPAIHFChargerDC jackSystemconnectorPop-PortFigure 1. Baseband block diagramUEMEK supplies both Baseband and RF with power via built in voltage regulators, which are connected to the battery. The RF parts use mainly 2.78 V and the Baseband parts 1.8V I/O voltage. The UPP core is supplied with programmable core voltage of 1.0V, 1.3V or 1.5V. UEMEK includes 7 linear LDO (Low Drop-Out) regulators for Baseband and 7 regulators for RF. It also includes 4 current sources for biasing purposes and internal usage. The UEMEK is furthermore supplying the SIM interface with a programmable voltage of 1.8V or 3V. Note: 5V SIM cards are no longer supported by DCT-4 generation Baseband. UPP operates from a 26 MHz clock coming from the RF ASIC Helga. The clock signal is divided by two down to the nominal system clock frequency of 13 MHz. The DSP and MCU contain PLLs, which can multiply the system clock to a higher frequency.New A4PC Template especially for UlmCopyright © Nokia Mobile Phones6 ( 64 ) CONFIDENTIAL Nokia Mobile Phones08-Apr-04 错误！错误！未知的文档属性名称A real time clock function is integrated into the UEMEK, which utilizes the same 32kHz clock supply as the sleep clock. The communication between UEMEK and UPP is implemented using two bi-directional serial busses, CBUS and DBUS. The CBUS is controlled by the MCU and operates at a speed of 1 MHz. The DBUS is controlled by the MCU and operates at a speed of 13 MHz. Both processors are located in the UPP. The UEMEK ASIC handles the analog interface between the Baseband and the RF section. UEMEK provides A/D and D/A conversion of the in-phase and quadrature receive and transmit signal paths and also A/D and D/A conversions of received and transmitted audio signals to and from the user interface. The UEMEK supplies the analog TXC and AFC signals to RF section according to UPP .signal control. There are also separate signals for PDM coded audio. Digital speech processing is handled by the DSP inside UPP ASIC. UEMEK is a dual voltage circuit, the digital parts are running from the baseband supply 1.8V and the analog parts are running from the analog supply 2.78V. Also VBAT is directly used (Vibra, LED-driver, Audio amplifier). The Baseband supports both internal and external microphone inputs and speaker outputs. Keypad tones, DTMF, and other audio tones are generated and encoded by the UPP and transmitted to the UEMEK for decoding. An external vibra alert control signals are generated by the UEMEK with separate PWM outputs.

These two dies are stacked on each other in one package, The functionality of the flash memory is the same as for other generic BB4.0 products.The combo is supplied by single 1,8 V for read, write and erase operations. For accelerated flash programming, VID = 9.0 V has to be applied to VPP input of the combo device.The combo memory is housed in a 44-ball FBGA.Figure 4. Combo memory4.2 Energy managementThe energy management of RH37 is based on BB 4.0 architecture. A so-called semi fixed battery (BL-5B) supplies power primarily to UEMEK ASIC and the RF PA. The UEMEK includes several regulators to supply RF and Baseband. It provides energy management including power up/down procedure.(If the main battery is not present, a cell capacitor maintains backup power supply for the RTC part of UEMEK)4.2.1 Modes of operationThe Baseband engine has six different functional modes: Since the UEMEK controls the regulated power distribution; each of these states affects the general functionality of the phone.1. No supply2. Backup3. Acting Dead4. Active5. Sleep6. ChargingConfidential Staffan Lamberg4.2.2 No SupplyIn NO_SUPPLY mode, the phone has no supply voltage. This mode is due to disconnection of main battery and backup battery or low battery voltage level in both of the batteries.Phone is exiting from NO_SUPPLY mode when sufficient battery voltage level is detected. Battery voltage can rise either by connecting a new battery with VBAT > V MSTR+ or by connecting charger and charging the battery above V MSTR+.4.2.3 BackupIn BACKUP mode the backup battery has sufficient charge but the main battery can be disconnected or empty (VBAT < V MSTR and VBACK > VBU COFF).VRTC regulator is disabled in BACKUP mode. VRTC output is supplied without regulation from backup battery (VBACK). All the other regulators are disabled.4.2.4 Acting DeadIf the phone is off when the charger is connected, the phone is powered on but enters a state called ”Acting Dead”. To the user, the phone acts as if it was switched off. A battery-charging alert is given and/or a battery charging indication on the display is shown to acknowledge the user that the battery is being charged.4.2.5 ActiveIn the Active mode the phone is in normal operation, scanning for channels, listening to a base station, transmitting and processing information. There are several sub-states in the active mode depending on if the phone is in burst reception, burst transmission, if DSP is working etc. In Active mode the RF regulators are controlled by SW writing into UEMEK´s registers wanted settings: VR1A can be enabled or disabled. VR2 can be enabled or disabled and its output voltage can be programmed to be 2.78V or 3.3V. VR4 -VR7 can be enabled, disabled, or forced into low quiescent current mode. VR3 is always enabled in Active mode.4.2.6 Sleep ModeSleep mode is entered when both MCU and DSP are in stand–by mode. Both processors control sleep-mode. When SLEEPX signal (low) is detected UEMEK enters SLEEP mode. VCORE, VIO and VFLASH1 regulators are put into low quiescent current mode. All the RF regulators are off in SLEEP. When SLEEPX=1 detected UEMEK enters ACTIVE mode and all functions are activated.The sleep mode is exited either by the expiration of a sleep clock counter in the UEMEK or by some external interrupt, generated by a charger connection, key press, headset connection etc. In sleep mode VCTCXO is shut down and 32 kHz sleep clock oscillator is used as reference clock for the Baseband.Confidential Staffan Lamberg4.2.7 ChargingIn RH37 the battery type/size is indicated by a BSI-resistor. The resistor value corresponds to a specific battery capacity. Also BTEMP, NTC resistor, is located on an engine board.The battery voltage, temperature, size and current are measured by the UEMEK controlled by the charging software running in the UPP.The charging control circuitry (CHACON) inside the UEMEK controls the charging current delivered from the charger to the battery. The battery voltage rise is limited by turning the UEMEK switch off when the battery voltage has reached 4.2 V. Charging current is monitored by measuring the voltage drop across a 220 mΩ resistor.4.3 Power distributionUnder normal conditions, the battery powers the Baseband module. Individual regulators located within the UEMEK regulate the battery voltage VBAT. These regulators supply the different parts of the phone. 8 regulators are dedicated to the RF module and 6 to the Baseband module.The VSIM regulator is able to deliver both 1,8V and 3,0 V DC and thus supporting two different SIM technologies.The regulator VCORE is likewise adjustable by the MCU. VCORE supplies the core logic of the UPP.The system connector provides a voltage to supply accessories.The white LEDs need a higher voltage supply than the battery can supply and are fed by a separate external voltage regulator.VBAT is directly distributed to the RF power amplifier, audio power amplifier and external Baseband regulators.。

For information about PCRs that are ﬁxed for this release, see the What’s New In Virtuoso Schematic Editor in 5.1.41.Important: Only the problems and solutions that were known at release time are available in this document. An up-to-date list of known problems for the schematic editor is published on the SourceLink®online customer support system.PCR 784954: Problem creating netSet property on instance with terminal as inherited connectionDescription:There is a current limitation with inherited connections where iterated instances, for example x<0:3>, cannot be used as intended.This is because of a limitation in the CDBA and OpenAccess2.0databases,in that there are no placeholders to store property information on a per-bit instance basis.Although you can have netSet on an iterated instance,care must be taken as it will overwrite ALL bits identically.Note:This impacts all DFII applications, and is not exclusive to inherited connections. The issue originates from the limitation of not being able to have bitInstance property values. Solution:The workaround is to create multiple instances,for example,x<0>,x<1>,x<2>, and x<3> rather than a single iterated instance named, in this case,x<0:3>.PCR781085:Cannot access Edit menu commands(client software license problems)Description:Due to changes in the client license server software,introduced in the IC 5.1.41USR1 release,you may encounter problems accessing certain schematic editor functionality, such as the Edit menu options.Previously,all IC releases used the same client software,Softshare7.2,however from IC5.1.41USR1, the client version was updated to 10.1.3.Note:The new client software will be used in all 1H2005 base releases.Solution:If you are using products from multiple release streams,you must ensure that the latest client license (10.1.x) is being used.All IC5.1.41USR1, and beyond, applications require a 10.1.x license server, as they will not fully function with older license servers. Whereas license servers are backward compatible, working with older clients, a new client does not operate correctly with older servers.PCR 773356: Schematic route ﬂight shorts netsDescription:There can be a problem with the schematic router where shorts are created between nets when the route flight line command is used.Solution:As a workaround, you should perform the following:1.Define a SKILL procedure as follows:procedure( CCSrouteFlightLines()let((cv f_lines)cv = geGetEditCellView()f_lines = setof(x cv~>shapes x~>lpp == list("wire" "flight"))foreach(line f_linesgeSelectFig(line)schHiRouteFlightLine())t))2.Call this newly created function,for the cellview in question,and it will perform the routingof all ﬂight lines, one by one.PCR763396:Instance renumbering overﬂows when numeric entry>=2e10 Description:If you attempt to enter a number>=2e10in the“Start resulting sequence with index” field, of the Renumber Instances form (first select Design – Renumber Instances), the schematic editor will encounter problems due to a numeric overflow.This overflow causes further numeric entries in the index field to no longer be accepted, and for the schematic editor to continue to display solely on those components of the resultant overflow.Solution:This problem occurs because the renumber instances command uses signed, rather than unsigned, integers when generating the index.The field entry limit here is (2^31 - 1).A negative number can also be entered in the “Start resulting sequence index” field, and this will cause instances to be renumbered as appropriate. Note however, that instances with negative indices will not be renamed by subsequent applications of renumber instances.PCR 757323: ICMS and ICFB -V and -W indicate incorrectly built binaries Description:The Linux 3.0 platform causes error messages when using the-V and-W options with icms and icfb (the icde,layout and layoutPlus executables do not display this problem).For example:icms -WIncorrectly built binary which accesses errno or h_errno directly. Needs to be fixed. sub-version 5.10.41_USR1.7.39icms -VIncorrectly built binary which accesses errno or h_errno directly. Needs to be fixed.@(#)$CDS: icms.exe version 5.1.0 11/07/2004 23:07 () $ Note:This issue is not speciﬁc to the schematic editor,but is rather a general problem with the DFII workbenches.Solution:To workaround this you should set the following variable:PCR 742904: Schematic check and save gives warning about an invalid Verilog identiﬁerRelated PCR: 756222Description:If you activate the Verilog HDL Syntax rule option(in the Name tab of the Setup Schematic Rules Checks form, under Check – Rules Setup), and perform a check on an explicit pin inherited connections schematic, you may get an unexpected warning message related to a signal name not being a valid Verilog identifier. For example:Signal name “VSS!” is not a valid Verilog identifierThe problem here is with the “!” character sufﬁx, as it is not part of the string name, but is, instead,part of the inherited connections identiﬁcation.The warning is displayed because the “!” character is an illegal character in the Verilog name space.Solution:Although potentially confusing, you can safely ignore the warning message regarding the invalid identifier. This problem will be rectified in a future release.PCR 740262: Add Simulation Monitor not working with OpenAccess Description:Add simulation monitor functionality is not operating correctly with OpenAccess in the schematic editor.For example, if you select a schematic instance, then chose Check – Schematic Monitors – Add, to display the Add Simulation Monitor form, then click on the Auto Placement option, the CIW will display a list of warning messages similar to the following:\a schSimProbeAddForm->probeFormat->value="<name>=<time>:<state>""<name>=<time>:<state>"\w *WARNING* dbCreateInstWithPurpose: creating instances with purposes other than "cell" or "pin" is not supported.\w *WARNING* dbCreateInstWithPurpose: creating instances with purposes other than "cell" or "pin" is not supported.....Note:There are also similar problems when adding schematic monitors manually. Solution:For information only.。

This overview will describe some of the end-user features which may be implemented as a direct result of the level of integration found within the DPhone -II .The main feature required of a digital telephone is to convert the digital Pulse Code Modulated (PCM)information, being received by the telephone set, into an analog electrical signal. This signal is then applied to an appropriate audio transducer such that the information is ﬁnally converted into intelligible acoustic energy. The same is true of the reverse direction where acoustic energy is converted ﬁrst into an electrical analog and then digitized (into PCM) before being transmitted from the set. Along the way if the signals can be manipulated, either in the analog or the digital domains, other features such as gain control, signal generation and ﬁltering may be added. More complex processing of the digital signal is also possible and is limited only be the processing power available. One example of this processing power may be the inclusion of a complex handsfree switching algorithm. Finally, most electro-acoustic transducers (loudspeakers) require a large amount of power to develop an effective acoustic signal. The inclusion of audio ampliﬁers to provide this power is required.The DPhone -II features Digital Signal Processing (DSP) of the voice encoded PCM, complete Analog/Digital and Digital/Analog conversion of audio signals (Filter/CODEC) and an analog interface to the external world of electro-acoustic devices (Transducer Interface). These three functional blocks combine to provide a standard full-duplex telephone conversation utilizing a common handset. Selecting transducers for handsfree operation, as well as allowing the DSP to perform its handsfree switching algorithm, is all that is required to convert the full-duplex handset conversation into a half-duplex speakerphone conversation. In each of these modes,full programmability of the receive path and side-tone gains is available to set comfortable listening levels for the user as well as transmit path gain control for setting nominal transmit levels into the network.The ability to generate tones locally provides the designer with a familiar method of feedback to the telephone user as they proceed to set-up, and ultimately, dismantle a telephone conversation. Also,as the network slowly evolves from the dial pulse/DTMF methods to the D-Channel protocols it is essential that the older methods be available forbackward compatibility. As an example; once a call has been established, say from your ofﬁce to your home, using the D-Channel signalling protocol it may be necessary to use in-band DTMF signalling to manipulate your personal answering machine in order to retrieve messages. Thus the locally generated tones must be of network quality and not just a reasonable facsimile. The DPhone -II DSP can generate the required tone pairs as well as single tones to accommodate any in-band signalling requirement.Each of the programmable parameters within the functional blocks is accessed through a serial microcontroller port compatible with Intel MCS-51speciﬁcations.Functional DescriptionIn this section, each functional block within the DPhone -II is described along with all of the associated control/status bits. Each time a control/status bit(s) is described it is followed by the address register where it will be found. The reader is referred to the section titled ‘Register Summary' for a complete listing of all address map registers, the control/status bits associated with each register and a deﬁnition of the function of each control/status bit.The Register Summary is useful for future reference of control/status bits without the need to locate them within the text of the functional descriptions.Filter-CODECThe Filter/CODEC block implements conversion of the analog 3.3kHz speech signals to/from the digital domain compatible with 64kb/s PCM B-Channels.Selection of companding curves and digital code assignment are register programmable. These are CCITT G.711 A-law or µ-Law, with true-sign/Alternate Digit Inversion or true-sign/Inverted Magnitude coding, respectively. Optionally, sign-magnitude coding may also be selected for proprietary applications.The Filter/CODEC block also implements transmit and receive audio path gains in the analog domain.These gains are in addition to the digital gain pad provided in the DSP section and provide an overall path gain resolution of 0.5dB. A programmable gain,voice side-tone path is also included to provide proportional transmit speech feedback to the handset receiver so that a dead sounding handset is not encountered. Figure 3 depicts the nominal half-channel and side-tone gains for the DPhone -II .MT90947-49On PWRST (pin 6) the Filter/CODEC defaults such that the side-tone path, dial tone ﬁlter and 400Hz transmit ﬁlter are off, all programmable gains are set to 0dB and µ-Law companding is selected. Further,the Filter/CODEC is powered down due to the PuFC bit (Transducer Control Register, address 0Eh) being reset. This bit must be set high to enable the Filter/CODEC.The internal architecture is fully differential to provide the best possible noise rejection as well as to allow a wide dynamic range from a single 5 volt supply design. This fully differential architecture is continued into the Transducer Interface section to provide full chip realization of these capabilites.A reference voltage (V Ref ), for the conversion requirements of the CODER section, and a bias voltage (V Bias ), for biasing the internal analog sections, are both generated on-chip. V Bias is also brought to an external pin so that it may be used for biasing any external gain plan setting ampliﬁers. A 0.1µF capacitor must be connected from V Bias to analog ground at all times. Likewise, although V Ref may only be used internally, a 0.1µF capacitor from the V Ref pin to ground is required at all times. It is suggested that the analog ground reference point for these two capacitors be physically the same point.To facilitate this the V Ref and V Bias pins are situated on adjacent pins.The transmit ﬁlter is designed to meet CCITT G.714speciﬁcations. The nominal gain for this ﬁlter path is 0dB (gain control = 0dB). An anti-aliasing ﬁlter isSERIAL PORTDSP GAIN*FILTER/CODECTRANSDUCER INTERFACEPCMPCM–72 to +22.5 dB (1.5dB steps)DTMF,Tone Ringer &Handsfree–72 to +22.5 dB (1.5dB steps)Receive Filter Gain 0 to –7 dB (1 dB steps)Side-tone –9.96 to +9.96dB (3.32 dB steps)Side-tone Nominal Gain Transmit Filter Gain 0 to +7dB (1 dB steps)µ-Law –11 dB Α-Law –18.8 dB-6 dBSpeaker Gain 0 to –24 dB (8 dB steps)Receiver DriverSpeaker Phone Driver 0.2dB*Tone Ringer (input from DSP)Transmit GainM U Xµ-Law –6.3 dB Α-Law –3.7 dB µ-Law 6.1dB Α-Law 15.4dBMIC+MIC–M+M–-6 dB HSPKR+HSPKR–SPKR+SPKR–Speakerphone Speaker (40Ω nominal)(32Ω min)Handsfree mic Transmitter microphoneHandset Receiver (150Ω)Transmit Internal to DeviceExternal to DeviceDIGITAL DOMAINANALOG DOMAIN7575Note: *gain the same for A-Law and m −LawReceiveFigure 3 - Audio Gain PartitioningMT90947-50included. This is a second order lowpass implementation with a corner frequency at 25kHz.Attenuation is better than 32dB at 256 kHz and less than 0.01dB within the passband.An optional 400Hz high-pass function may be included into the transmit path by enabling the Tfhp bit in the Transducer Control Register (address 0Eh).This option allows the reduction of transmitted background noise such as motor and fan noise.The receive ﬁlter is designed to meet CCITT G.714speciﬁcations. The nominal gain for this ﬁlter path is 0 dB (gain control = 0dB). Filter response is peaked to compensate for the sinx/x attenuation caused by the 8kHz sampling rate.The Rx ﬁlter function can be altered by enabling the DIAL EN control bit in the Transducer Control Register (address 0Eh). This causes another lowpass function to be added, with a 3dB point at 1000Hz. This function is intended to improve the sound quality of digitally generated dial tone received as PCM.Transmit sidetone is derived from the Tx ﬁlter and is subject to the gain control of the Tx ﬁlter section.Sidetone is summed into the receive path after the Rx ﬁlter gain control section so that Rx gain adjustment will not affect sidetone levels. The side-tone path may be enabled/disabled with the SIDE EN bit located in the Transducer Control Register (address 0Eh). See also STG 0-STG 2(address 0Bh).Transmit and receive ﬁlter gains are controlled by the TxFG 0-TxFG 2 and RxFG 0-RxFG 2 control bits respectively. These are located in the FCODEC Gain Control Register 1 (address 0Ah). Transmit ﬁlter gain is adjustable from 0dB to +7dB and receive ﬁlter gain from 0dB to -7dB, both in 1dB increments.Side-tone ﬁlter gain is controlled by the STG 0-STG 2control bits located in the FCODEC Gain Control Register 2 (address 0Bh). Side-tone gain is adjustable from -9.96dB to +9.96dB in 3.32dB increments.Law selection for the Filter/CODEC is provided by the A/µ companding control bit while the coding scheme is controlled by the sign-mag/CCITT bit.Both of these reside in the General Control Register (address 0Fh).Digital Signal ProcessorThe DSP block is located, functionally, between the serial ST -BUS port and the Filter/CODEC block. Itsmain purpose is to provide both a digital gain control and a half-duplex handsfree switching function. The DSP will also generate the digital patterns required to produce standard DTMF signalling tones as well as single tones and a tone ringer output. A programmable (ON/OFF) offset null routine may also be performed on the transmit PCM data stream. The DSP can generate a ringer tone to be applied to the speakerphone speaker during normal handset operation so that the existing call is not interrupted.The main functional control of the DSP is through two hardware registers which are accessible at any time via the microport. These are the Receive Gain Control Register at address 1Dh and the DSP Control Register at address 1Eh. In addition, other functional control is accomplished via multiple RAM-based registers which are accessible only while the DSP is held in a reset state. This is accomplished with the DRESET bit of the DSP Control Register. Ram-based registers are used to store transmit gain levels (20h for transmit PCM and 21h for transmit DTMF levels), the coefﬁcients for tone and ringer generation (addresses 23h and 24h),and tone ringer warble rates (address 26h). All undeﬁned addresses below 20h are reserved for the temporary storage of interim variables calculated during the execution of the DSP algorithms. These undeﬁned addresses should not be written to via the microprocessor port. The DSP can be programmed to execute the following micro-programs which are stored in instruction ROM, (see PS0 to PS2, DSP Control Register, address 1Eh). All program execution begins at the frame pulse boundary.PS2 PS1 PS0Micro-program000Power up reset program1Transmit and receive gain control program; with autonulling of the transmit PCM, if the AUTO bit is set (see address 1Dh)010DTMF generation plus transmit and receive gain control program (autonull available via the AUTO control bit)011Tone ringer plus transmit and receive gain control program (autonull available via the AUTO control bit)100handsfree switching program101110Last three selections reserved111MT90947-51Note: For the DSP to function it must be selected tooperate, in conjunction with the Filter/Codec, in one of the B-Channels. Therefore, one of the B-Channel enable bits must be set (see Timing Control, address 15h : bits CH 2EN and CH 3EN).Power Up reset ProgramA hardware power-up reset (pin 6,PWRST) will initialize the DSP hardware registers to the default values (all zeros) and will reset the DSP program counter. The DSP will then be disabled and the PCM streams will pass transparently through the DSP . The RAM-based registers are not reset by the PWRST pin but may be initialized to their default settings by programming the DSP to execute the power up reset program. None of the micro-programs actually require the execution of the power up reset program but it is useful for pre-setting the variables to a known condition. Note that the reset program requires one full frame (125µSec) for execution.Gain Control ProgramGain control is performed on converted linear code for both the receive and the transmit PCM. Receive gain control is set via the hardware register at address 1Dh (see bits B0 - B5) and may be changed at any time. Gain in 1.5dB increments is available within a range of +22.5dB to -72dB. Normal operation usually requires no more than a +20 to -20dB range of control. However, the handsfree switching algorithm requires a large attenuation depth to maintain stability in worst case environments, hence the large (-72 dB) negative limit. Transmit gain control is divided into two RAM registers, one for setting the network level of transmit speech (address 20h) and the other for setting the transmit level of DTMF tones into the network (address 21h). Both registers provide gain control in 1.5dB increments and are encoded in the same manner as the receive gain control register (see address 1Dh, bits B0 - B5). The power up reset program sets the default values such that the receive gain is set to -72.0 dB, the transmit audio gain is set to 0.0dB and the transmit DTMF gain is set to -3.0dB (equivalent to a DTMF output level of -4dBm0 into the network).Optional Offset NullingTransmit PCM may contain residual offset in the form of a DC component. An offset of up to ±ﬁfteen linear bits is acceptable with no degradation of the parameters deﬁned in CCITT G.714. The DPhone -II ﬁlter/CODEC guarantees no more than ±ten linear bits of offset in the transmit PCM when the autonullroutine is not enabled. By enabling autonulling (see AUTO in the Receive Gain Control Register, address 1Dh) offsets are reduced to within ±one bit of zero.Autonulling circuitry was essential in the ﬁrst generations of Filter/Codecs to remove the large DC offsets found in the linear technology. Newer technology has made nulling circuitry optional as offered in the DPhone -II .DTMF and Gain Control ProgramThe DTMF program generates a dual cosine wave pattern which may be routed into the receive path as comfort tones or into the transmit path as network signalling. In both cases, the digitally generated signal will undergo gain adjustment as programmed into the Receive Gain Control and the Transmit DTMF Gain Control registers. The composite signal output level in both directions is -4dBm0 when the gain controls are set to 2Eh (-3.0 dB). Adjustments to these levels may be made by altering the settings of the gain control registers. Pre-twist of 2.0dB is incorporated into the composite signal. The frequency of the low group tone is programmed by writing an 8-bit coefﬁcient into Tone Coefﬁcient Register 1 (address 23h), while the high group tone frequency uses the 8-bit coefﬁcient programmed into Tone Coefﬁcient Register 2 (address 24h). Both coefﬁcients are determined by the following equation:COEFF = 0.128 x Frequency (in Hz)where COEFF is a rounded off 8 bit binary integer A single frequency tone may be generated instead of a dual tone by programming the coefﬁcient at address 23h to a value of zero. In this case thefrequency of the single output tone is governed by the coefﬁcient stored at address 24h.Table 1DTMF Signal to distortion:The sum of harmonic and noise power in the frequency band from 50Hz to 3500Hz is typically more than 30dB below the power in the tone pair. All individual harmonics are typically more than 40dB below the level of the low group tone.Frequency(Hz)COEFActual Frequency%Deviation69759h 695.3-.20%77063h 773.4+.40%8526Dh 851.6-.05%94179h 945.3+.46%12099Bh 1210.9+.20%1336ABh 1335.9.00%1477BDh 1476.6-.03%1633D1h1632.8-.01%MT90947-52Table 1 gives the standard DTMF frequencies, the coefﬁcient required to generate the closest frequency, the actual frequency generated and the percent deviation of the generated tone from the nominal.Tone Ringer and Gain Control ProgramA locally generated alerting (ringing) signal is used to prompt the user when an incoming call must be answered. The DSP uses the values programmed into Tone Coefﬁcient Registers 1 and 2 (addresses 23h and 24h) to generate two different squarewave frequencies in PCM code. The amplitude of the squarewave frequencies is set to a mid level before being sent to the receive gain control block. From there the PCM passes through the decoder and receive ﬁlter, replacing the normal receive PCM data,on its way to the loudspeaker driver. Both coefﬁcients are determined by the following equation:COEFF = 8000/Frequency (Hz)where COEFF is a rounded off 8 bit binary integer The ringer program switches between these two frequencies at a rate deﬁned by the 8-bit coefﬁcient programmed into the Tone Ringer Warble Rate Register (address 26h). The warble rate is deﬁned by the equation:Tone duration (warble frequencyin Hz) = 500/COEFFwhere 0 < COEFF < 256, a warble rate of 5-20Hz is suggested.An alternate method of generating ringer tones to the speakerphone speaker is available. With this method the normal receive speech path through the decoder and receive ﬁlter is uninterrupted to the handset,allowing an existing conversation to continue. The normal DSP and Filter/CODEC receive gain control is also retained by the speech path. When the OPT bit (DSP Control Register address 1Eh) is set high the DSP will generate the new call tone according to the coefﬁcients programmed into registers 23h, 24h and 26h as before. In this mode the DSP output is no longer a PCM code but a toggling signal which is routed directly through the New Call Tone gain control section to the loudspeaker driver. Refer to the section titled ‘New Call Tone’.Handsfree ProgramA half-duplex speakerphone program, fully contained on chip, provides high quality gain switching of the transmit and receive speech PCM to maintain loop stability under most network and local acoustic environments. Gain switching is performed in continuous 1.5dB increments and operates in a complimentary fashion. That is, with the transmit path at maximum gain the receive path is fully attenuated and vice versa. This implies that there is a mid position where both transmit and receive paths are attenuated equally during transition. This is known as the idle state.Of the 64 possible attenuator states, the algorithm may rest in only one of three stable states; full receive, full transmit and idle. The maximum gain values for full transmit and full receive are programmable through the microport at addresses 20h and 1Dh respectively, as is done for normal handset operation. This allows the user to set the maximum volumes to which the algorithm will adhere. The algorithm determines which path should maintain control of the loop based upon the relative levels of the transmit and receive audio signals after the detection and removal of background noise energy. If the algorithm determines that neither the transmit or the receive path has valid speech energy then the idle state will be sought. The present state of the algorithm plus the result of the Tx vs. Rx decision will determine which transition the algorithm will take toward its next stable state. The time durations required to move from one stable state to the next are parameters deﬁned in CCITT Recommendation P .34 and are used by default by this algorithm (i.e., build-up time, hang-over time and switching time).Quiet CodeThe DSP can be made to send quiet code to the decoder and receive ﬁlter path by setting the RxMUTE bit high. Likewise, the DSP will send quiet code in the transmit (DSTo) path when the TxMUTE bit is high. Both of these control bits reside in the DSP Control Register at address 1Eh. When either of these bits are low, their respective paths function normally.MT90947-53Transducer InterfacesFour standard telephony transducer interfaces are provided by the DPhone -II . These are:±The handset microphone inputs (transmitter),pins M+/M- and the speakerphone microphone inputs, pins MIC+/MIC-. The transmit path is muted/not-muted by the MIC EN control bit.Selection of which input pair is to be routed to the transmit ﬁlter ampliﬁer is acomplished by the MIC/HNSTMIC control bit. Both of these reside in the Transducer Control Register (address 0Eh). The nominal transmit path gain may be adjusted to either 6.1dB (suggested for µ-Law)or 15.4dB (suggested for A-Law). Control of this gain is provided by the MICA/u control bit (General Control Register, address 0Fh). This gain adjustment is in addition to the programmable gain provided by the transmit ﬁlter and DSP .±The handset speaker outputs (receiver), pins HSPKR+/HSPKR-. This internally compensated, fully differential output driver is capable of driving the load shown in Figure 4.This output is enabled/disabled by the HSSPKR EN bit residing in the Transducer Control Register (address 0Eh). The nominal handset receive path gain may be adjusted to either -12.3dB (suggested for µ-Law) or - 9.7dB (suggested for A-Law). Control of this gain is provided by the RxA/u control bit (General Control Register, address 0Fh). This gain adjustment is in addition to the programmable gain provided by the receive ﬁlter and DSP .±The loudspeaker outputs, pins SPKR+/SPKR-.This internally compensated, fully differential output driver is capable of directly driving 6.5vpp into a 40 ohm load. This output is enabled/disabled by the SPKR EN bit residing in the Transducer Control Register (address 0Eh). The nominal gain for this ampliﬁer is 0.2dB.C-ChannelAccess to the internal control and status registers of Mitel basic rate, layer 1, transceivers is through the ST -BUS Control Channel (C-Channel), since direct microport access is not usually provided, except in the case of the SNIC (MT8930). The DPhone -II provides asynchronous microport access to the ST -BUS C-Channel information on both DSTo and DSTi via a double-buffered read/write register (address 14h). Data written to this address is transmitted on the C-Channel every frame when enabled by CH 1EN (see ST -BUS/Timing Control).Figure 4 - Handset Speaker DriverLCDA twelve segment, non-multiplexed, LCD display controller is provided for easy implementation of various set status and call progress indicators. The twelve output pins (S n ) are used in conjunction with 12 segment control bits, located in LCD Segment Enable Registers 1&2 (addresses 12h and 13h), and the BackPlane output pin (BP) to control the on/off state of each segment individually.The BP pin drives a continuous 62.5Hz, 50% duty cycle squarewave output signal. An individual segment is controlled via the phase relationship of its segment driver output pin with respect to the backplane, or common, driver output. Each of the twelve Segment Enable bits corresponds to a segment output pin. The waveform at each segment pin is in-phase with the BP waveform when its control bit is set to logic zero (segment off) and is out-of-phase with the BP waveform when its control bit is set to a logic high (segment on). Refer to the LCD Driver Characteristics for pin loading information.MicroportA serial microport, compatible with Intel MCS-51(mode 0) speciﬁcations, provides access to all DPhone -II internal read and write registers. This microport consists of three pins; a half-duplex transmit/receive data pin (DATA1), a chip select pin (CS) and a synchronous data clock pin (SCLK).On power-up reset (PWRST) or with a software reset (RST), the DATA1 pin becomes a bidirectional (transmit/receive) serial port while the DATA2 pin is internally disconnected and tri-stated.HSPKR+HSPKR-75Ω75Ω1000 pF150 ohm load(speaker)1000 pFgroundMT9094。

DB8 DB4 音频处理器简介说明书

1Thank you for choosing DB8 or DB4 as your next step in audio. Even if the near future is analog we are convinced you have chosen wisely. Consistency in Loudness is the single most important audio issue to get right in broadcast today. DB8 and DB4 employ cutting edge technology to enable stations get rid of listener complaints about jumping levels, and to transmit in analog and digital with optimum processing for both feeds.The Difference Between DB8 and DB4DB8 contains four independent processors in one frame -DB4 holds two. Two or four processors is the onlydifference, and DB4 is even preset compatible with DB8.DB8 is designed for large broadcast centers, while DB4may be a more appropriate match for a regional station,but they share the same processing, the same presets and the same physical I/O structure - and even the sameprogram to control them. Many machines of both types can be controlled from one Icon program (included with this package), and they will identify themselves over a network,be it local or remotely located machines.Software and Manual for DB8 and DB4Software updates for both machines are always released simultaneously, and the two machines share the same manual. The relevat differences are highlighted. Instead of both names being printed throughout the manual, "DB8" is used as a generic term.PresetsDB8 and DB4 include a number of international standard presets ready for use. More presets are continuously made available in software updates, and from the TC web-site.Presets are based on information from broadcastersaround the world. Some are subtle, some aggressive, but they all provide outstanding audio resolution, never before available in a broadcast processor.Identify Your OpportunitiesIf your station is an early mover in digital and seeking to identify advantages, DB8 and DB4 will provide you with all the possibilities you need to experiment and find the right competitive angle. The processors can also adapt to your audience's changing needs, or audio strategy could even be changed from program to program.TC Electronic, Sindalsvej 34, DK-8240 Risskov *********************Introduction DB8/DB4 Rev 1.60English versionTechnical IntegritySynchronous 48kHz sampling and 48 bit processing throughout. Wide range, high order jitter rejection. The DB8/DB4 platform is without compromises. In fact,hundreds of machines could be cascaded without even degrading the transmitted sound. If optional analoginterfacing cards are added, they too represent state of the art technology with 96kHz sampling and mastering quality dynamic range. Analog prescaling is under remote control to NAB and EBU standards or even up to +30dBu Inputs.FoundationTC's involvement with high quality digital audio dates back to the mid eighties with pre-DSD technology being employed in the still ubiquitous delay, 2290. TC'scommitment to digital excellence continued over the years with equipment for the music, film and mastering industries.The multichannel processing in DB8 and DB4, for instance,was originally developed for film. Those tools have been adjusted for broadcast use and are now part of your arsenal. Or dynamics control, where some of the latest end-listener distortion canceling methods originally invented for mastering have been build in.Seven years experience with analog and digital broadcast combined with the know-how of skilled engineers is the strong base of the DB8/DB4 platform. From the purist and quality conscious hardware engineers to software writers of whom some were involved with designing the MPEGcodecs, the team forms a competent, non-dogmatic design group ready to take broadcast audio to the next level.We are confident you will value your new possibilities.。

翻译黄金管弦乐的说明书样本

翻译黄金管弦乐阐明书（连载）作者：断剑本文为本人依照在网上搜索来英文手册《The Complete Guide - EWQLSO》翻译得来，为非赚钱性作品，仅供广大兴趣者学习之用，请勿用于商业用途，谢谢！由于本人水平有限，翻译中难免有各种错误，但愿高人能指正。

英文原版手册我曾经发过，在这里（名字不同样内容同样）1手册有100多页，我只翻了一小某些，背面某些我会一边翻译一边发布，但愿人们关注和支持。

安装EWQLSO The EASTWEST/QUANTUM LEAP SYMPHONIC ORCHESTRA （有关帖子诸多，略过）用EWQLSO制作音乐犹如真实管弦乐队同样，EWQLSO采样文献也被分为四组：弦乐组（strings）木管组（woodwinds）铜管组（brass）打击乐组（percussion）每个组内又包具有许多乐器。

例如：弦乐组包括了小提琴、中提琴、大提琴、大提贝以及竖琴。

EWQLSO又进一步将每种乐器划分为独奏和群组两个类别。

并且在小提琴组里，群组音色又被分为“18小提琴”和“11小提琴”，以体现老式乐队中第一小提琴组和第二小提琴组声音区别。

因而，在EWQLSO中，对于乐器定义与咱们在真实世界中稍微有些不同，解释如下;当咱们用EWQLSO自带Kompakt采样器载入一种采样音色时，你将在打开菜单中看见几种不同层。

下图中显示就是白金版中加载音色时显示三个层。

让咱们先忽视中间那层最小菜单，留在后来讨论。

这层子菜单只存在于白金版中，除非你建立自己子菜单。

左边菜单在EWQLSO中称之为乐器。

在列表中，上方是全编制管弦乐队中常规五个弦乐群组，下方是三个独奏乐器（大提琴、竖琴和小提琴），以及一种额外乐器：LARGE STRING SECTION 以再现一种全体弦乐组齐奏声音。

右边菜单在EWQLSO中称之为演奏法。

这是由演奏家以尽量多演奏方式来演奏乐器所采集而成采样。

如何使用EWQLSO乐器及演奏法有诸各种办法来制作管弦乐队中大多数乐器声音。

Listen EVERYWHERE 故障排除指南说明书

Listen EVERYWHERE Troubleshooting GuideContentsOverview ------------------------------------------------------------------------------------------------------------------- 1 Unable to Perform a Successful Venue Scan -------------------------------------------------------------------- 1 Front Power LED is Solid ------------------------------------------------------------------------------------------- 2 Front Power LED is Blinking Steadily (1 Blink Per Second) ------------------------------------------------ 4 Front Power LED is Blinking Rapidly (2 Blinks Per Second) ----------------------------------------------- 4 Server is Unable to Connect to Cloud Services ----------------------------------------------------------------- 5 High Latency, Noise, Crackling, or Dropouts in Audio --------------------------------------------------------- 5 No Audio or Partial Audio --------------------------------------------------------------------------------------------- 7Overview:The purpose of this tech note is to provide a troubleshooting guide for the ListenEVERYWHERE (LE) server. Most of the issues outlined are usually encountered when initially installing the LE server or after altering a pre-existing installation of the LE server in asignificant way (i.e., installing into a different location, changing networking or audio equipment, etc.). There may be issues or resolutions that extend beyond this document. If so, please do not hesitate to contact Listen Technical Support using the contact information located at the end of this document.Unable to Perform a Successful Venue Scan:If you are reviewing this section, you are not able to connect to the Listen EVERYWHERE server through the Listen EVERYWHERE app using the Venue Scan option. The user will witness a 30-second countdown timer and/or an error message. To preface, theuser must be physically present in the venue location where ListenEVERYWHERE is installed and must be connected to the samenetwork. The server is not designed to stream over the internet ortraverse networks. The Venue Scan feature also requires theallowance of particular ports and services mentioned later in thissection. If this is not desired or possible in the venue, please consultthe Mobile App Connection Methods tech note for alternativeconnection methods.Note: The first time the app is opened on devices running iOS 14 or higher, you will see the prompt “Listen EVERYWHERE would like to find and connect to devices on your local network. This app will beable to discover and connect to devices on the networks you use”, press “OK”. This can be changed atany time in Settings > Privacy > Local Network on the iOS platform.Front Power LED is SolidThis section will provide solutions in a situation where a Venue Scan will fail while thefront power LED on the LE server is solid.•Enable Multicast UDP / Multicast DNS (mDNS) on the network. This is a common problem on guest networks or networks with high levels of security because thisfeature may be disabled. Multicast DNS (mDNS) is used in the discovery processfor the app and the server to connect via a network scan. This then allowsautomatic connection when the app is opened. To enable mDNS, perform thefollowing:o Add the following services to the allowed list in the Gateway/WAP mDNS settings: Array▪_ExXothermic._tcp▪_AsClient_ExXothermic._tcpo Open Port 5353.o Add the mDNS IP address to theallowed subnets list. 224.0.0.251 isthe most common mDNS IPaddress, but it could be any of the224.0.0.0/24 range.•Whitelist the LE server on the network. Onguest networks and VLANs, it’s possiblethat client isolation is enabled. Clientisolation prevents connected wirelessdevices from communicating with otherdevices on the network (such asiOS/Android devices communicating withthe LE server) and disables mDNS. Inconjunction with enabling mDNS on thenetwork (see previous bullet point), the IPaddress or MAC address must be added tothe allowed address list (Whitelist) for the GuestNetwork/VLAN in the Router and/or WAP configuration.•Expand the allocation of IP addresses. The network may be limited by the number of host devices that can acquire an IP address (i.e., connect to thenetwork). This will be evident when the LE server is successfully connected to the network but only some users cannot successfully connect to the network and therefore, are unable to successfully perform a Venue Scan in the LE app. In that case, the subnet mask may need to be expanded to include more hosts. A calculator can be found here. For networks with a single Listen EVERYWHERE server, it is recommended to set the subnet mask to at least 255.255.252.0/22 to accommodate the 1000 user specification of the server. This may vary based on the network infrastructure needs. Class B (default subnet mask of255.255.0.0) is best for medium to large venues.•Consider IP address lease time. Lease time refers to how long a device will reserve an IP address on a network before it is renewed and re-added to the IP address pool availability. Similar to expanding the IP address allocation, the IP address lease time may also be adjusted based on the needs of the venue. It’s recommended to place a Listen EVERYWHERE server on a network with a 24-hour lease time so that devices do not encounter any disruption whilestreaming audio through the Listen EVERYWHERE app. However, a venue may want to consider lowering the lease time in high traffic environments or forapplications that required a user to be connected for a predetermined finite amount of time (e.g., a guided tour).•Ensure that users are connected to the correct network and are not using mobile data. As mentioned previously, make sure that users are connected to the same network as the LE server. To help verify, it may be beneficial toperform a network scan from a mobile device using a network analyzer app.Usually, the LE server should appear with the Server ID (e.g., AEL6-XXXX-XXXX-XXX) as the name and “WIBRAIN” as the manufacturer. If using the LE server on a network without internet connection, some devices may have troubleconnecting. Below are a few tips to help connect to these networks: o When first connecting to the network, you may see a prompt to stay connected even if the network does not have internet. Select Yes orKeep Trying Wi-Fi. Do not manually switch to mobile or cellular data.o Forget the network and reconnect. This may elicit a prompt to stay connected even if the network does not have internet. Select Yes orKeep Trying Wi-Fi. Do not manually switch to mobile or cellular data.o Turn off Mobile / Cellular Data and connect to the network.o Turn on Airplane Mode and connect to the network.Front Power LED is Blinking Steadily (1 Blink Per Second)This section will provide solutions in a situation where a Venue Scan will fail while the front power LED on the LE server is blinking once per second.By default, the Listen EVERYWHERE server is designed to acquire an IP address automatically from a DHCP server. This is typically the router. While acquiring the IP address from the network, the user will see the power LED blink once per second for roughly 30 seconds. If the blinking pattern persists beyond that, an IP address isn’t properly being assigned to the server or the internal components are not functioning properly.•Verify that a DHCP server / router is properly setup and installed. Follow the steps provided by the manufacturer of the networking hardware to set up andprepare the network for use. Sometimes, these devices may fail over time.Performing a factory reset on the networking equipment and following thesetup procedures may resolve the issue.•Check the network cable and Ethernet port. The network cable may be faulty, disconnected, or connected into the wrong Ethernet port on the network switch or router. The Ethernet LAN port may also be faulty, disabled, or configuredincorrectly.•Check the Power supply. A faulty or incorrect power supply will cause internal components of the Listen EVERYWHERE server to function incorrectly. The LEserver uses a 5V / 6.0A / 30W power supply.Front Power LED is Blinking Rapidly (2 Blinks Per Second)This section will provide solutions in a situation where a Venue Scan will fail while the front power LED on the LE server is blinking twice per second.•Verify that the network settings placed on the Listen EVERYWHERE server are correct. Network settings can be adjusted on the LE server through the ServerAdmin interface. Some errors, such as IP address conflicts on the network, willoccur after the configuration is saved and the server is rebooted. When errorslike this are encountered, the front panel LED status will flash in panic mode (2blinks per second) indicating the server has an improper network configuration and cannot communicate on the network. When this happens, the server willrevert to a known working DHCP configuration after 5 minutes.Server is Unable to Connect to Cloud Services:•internet access.•Enable ports and services. This will likely be necessary if the network has a high level of security or firewall in place. Cloud Services communicates via HTTP with the LE server through * over port 1025, with updates communicating over port 80.Refer to Figure 1 on Page 2.High Latency, Noise, Crackling, or Dropouts in Audio:If you are reviewing this section, you are able to successfully connect to the Listen EVERYWHERE server through the Listen EVERYWHERE app. However, the latency of the audio stream through the app seems excessively high or the audio stream has excessive noise, crackling, or dropouts. These audio effects may be heard immediately, occasionally, or infrequently. An example can be heard here.The average latency on the Listen EVERYWHERE server is 60ms but can vary by network and device.•Upgrade the networking equipment. Older and/or low-cost networking equipment may result in unreliable and slower packet delivery, especially when many users areconnected to a single network. It is highly recommended to use high-end consumer-grade networking equipment or enterprise-grade networking equipment to improvepacket reliability and speed. More information and recommended networkingequipment can be found in our Wireless Access Point Optimization for ListenEVERYWHERE tech note.• Do not use a mesh network . A mesh network iscomprised of multiple nodes that communicatewith each other to provide wireless access to asingle network. These nodes may also be calledpoints or extenders. You may also think of thesenodes as being wirelessly daisy-chained to oneanother. Mesh networks have a high likelihood ofcausing excessive latency, dropouts, andunwanted noise because it extends the pathwayfrom the user device to the Listen EVERYWHEREserver. Refer to Figure 2 on the right.• Use an open network (no encryption). Usingencryption can lower the number of users thatcan connect to the WAP and add latency to theLE system. TKIP encryption should not be used.• Enable Quality of Service (QoS) for the LE serveron the network . By default, the LE server uses the 0xB8 Type of Service/Differentiated Services(ToS/DS) tag so that audio data can be prioritized over other data traffic on the network. This priority allows the latency and dropouts to be as low and infrequent as possible while travelling over the network. The QoS setting may still need to be enabled on the managed network, especially if there are many other connected devices or there are existing QoS prioritizations on other connected devices.• Ensure that there is adequate Wi-Fi coverage. If latency improves as a user movescloser to the wireless access point or when there are less users connected to thenetwork, the venue may need to consider adding additional wireless access points for adequate coverage and bandwidth allocation. Network speeds can also be tested using third-party apps. Refer to our Wireless Access Point Optimization for ListenEVERYWHERE tech note for more details.• Consider network frequency . Typically, users will receive better performance on the5GHz frequency versus a 2.4GHz frequency. The 2.4GHz frequency can usually beturned off through your network’s admin interface. However, 2.4GHz frequencies will work more efficiently as the user moves further away from the access point. Both may be considered depending on your wireless access point placement.• Check your mobile device. Some third-party, low-cost and/or older mobile devices maynot have high computing power or strong Wi-Fi antennas. Test with multiple mobiledevices to isolate the problem. If the problem exists on one or few devices, it may benecessary to use an alternate mobile device to stream audio.•Set a static channel on the wireless access point(s). Many WAPs can automatically change channels to try and find one with the least interference. This feature can cause audio dropouts each time the channel changes, as often as every 20 seconds. If it does not settle on a channel after 30-60 minutes, it may be best to choose a channelmanually.•Check your Bluetooth device (if applicable). Bluetooth speakers and headphones can potentially cause an additional 200-700ms in latency. The amount of latency can varybetween Bluetooth devices. Utilizing devices with Bluetooth 5.0 or higher and Bluetooth Low Energy (BLE) can help reduce latency. If using a hearing aid or cochlear implantwith Bluetooth technology, try toggling between listening modes to reduce latency.Bluetooth devices are also susceptible to interference from Wi-Fi signals. Try movingcloser to the wireless access point.•Be mindful of cable runs. Cable runs from the audio source to the Listen EVERYWHERE server should be balanced to avoid introducing interference or noise. If an unbalanced cable is used, you can reduce noise by improving cable shielding, avoiding long cableruns (usually over 15ft), and by avoiding objects that can be picked up by the groundwire.•Avoid ground loops. A ground loop is characterized by the introduction of a humming noise in the audio and can occur when multiple devices are interconnected through a shared ground reference. Grounding is needed for both power and audio connections, so it’s important to not allow these ground references to create a loop within the device setup. When it comes to Listen EVERYWHERE, it may occur when the source audio,other audio devices, and LE server are connected to the same ground reference,usually in the form of a shared power strip or electrical outlets with interconnectedground references. In order to combat a ground loop occurrence, the equipment’scircuitry will need to be separated or a ground loop isolator can be installed.No Audio or Partial Audio:If you are reviewing this section, you are able to successfully connect to the Listen EVERYWHERE server through the Listen EVERYWHERE app. However, no audio or partial audio is heard on the channel after channel selection within the app. The LE server contains green LEDs on the front of the unit that will illuminate when audio is present and at an adequate level. This may help determine if the issue is audio-based or network-based and can be troubleshot accordingly.•Correctly connect audio to the Listen EVERYWHERE server. If the server is set up for mono, connect to a single terminal block input, or connect to one vertical pair of redand white RCA connections (LW-100P only). If the server is set up for stereo, connect toa pair of terminal block inputs, or connect to one RCA input on the left and one RCAinput on the right (LW-100P only). The LW-150 Dante connection handles both mono and stereo with the same connection. Refer to Figure 3 below.•Verify that audio cables being used are working properly or have been properly assembled. This can be tested by using a different cable. If a custom-made cable is being used, some wiring diagrams are available on our Audio Input Connection for Listen EVERYWHERE tech note to ensure that it had been made properly. A multimeter may also be used to check for continuity between the two connectors of the cable. •Verify that headphones are working properly. This can be tested by using a different pair of headphones and/or confirming that the audio can be heard through thespeaker of the smartphone or tablet used for streaming.•Audio input should be line level. Mic level audio sources are not meant to be used on the Listen EVERYWHERE server. Doing so may result in low level audio and pitch where no audio or only partial audio may be heard.•Ensure that traffic is enabled on port 16384. The LE Server sends RTP packets via UDP to the app over a range of ports, including dynamic ephemeral ports. The mobile app listens via UDP over port 16384. If these ports are not enabled, no audio will stream through the app. See Figure 1 on Page 2. It also may be necessary to perform anetwork scan or capture (e.g., through Wireshark) to identify which ports the network is utilizing. See example below.•Do not attempt to stream audio across different networks. Attempting to stream across different networks will likely end up producing no audio within the Listen EVERYWHERE app.Should you have any further questions or concerns, please contact Listen Technologies’Technical Services team at 1-800-330-0891 or**********************for assistance.。
