2M复用
PCM30/32路E1信号到STM-1复用过程(自己一个总结)(2010-09-29 17:58:33)转载标签：分类：网络宋体gb2312楷体复帧字节杂谈E1的速率为2048kbps，也就是125us传输一帧，1s时间内将传输8000帧，这是一个E1帧，每个E1帧包含着32路信号，其中有30路的用户信号，现在我想把它复用stm-1中，那么首先我取出8000帧的4帧，也就是说要将这8000帧的数据给2000等份，每一等份为4帧，将这4帧中的每一帧叫做E1基帧，这是相对于C12基帧来说的，其实就是C12基帧，只不过C12由E1的映射而来，可以是同步映射，也可以是异步映射。
同步映射比较简单，只要将E1的信号前后填充R字节（类似于mac帧中的pad填充字节），那么原本为32字节的E1就变成了现在的34字节的C12基帧了，现在开始引入复帧的概念，一个复帧由4个C12基帧构成，记住，这4个C12基帧都是同一个E1下的4帧数据（2000帧中的第一个4帧，在合成stm-1时，需要63路的E1，也就是63*30=1890路用户信号，每一路用户信号的速率其实是64kbps，每一帧中就只有1个字节的信息）。
看好了，现在要将C12变成VC12了，只要在各个C12基帧前分别添加POH开销v5、J2、N2、k4，那么此时的每一个VC12基帧就变为35个字节了，由VC12到TU12的变化就是在各个VC12基帧后分别加入TU-PTR指针v1、v2、v3、v4，那么此时的每一个TU12基帧就变为了36个字节，再重新强调一遍，此时的一路E1的8000帧数据，变成了2000帧的TU12复帧，每一个复帧由4个TU12基帧构成（Note:是一路E1，而不是四路E1）。
形成TU12后，我们就需要其余62路TU12的帮助了，因为一个STM-1信号需要63路的E1，其实其余的62路TU-12形成过程是一样的，在合成TUG-2过程中，每一个TUG-2需要3个TU12基帧，那么63路的E1信号就分配成21组，每组3路E1。

马尔杰尔30周年纪念电子管音箱手册说明书
1use. It allows you to control your amp’s channel switching (1,2 or 3) via MIDI program change messages. The Anniversary amp has an internal memory and can store Channel 1,2 or 3 selection in 128 MIDI addressable patches. These correspond to the 0 - 127 MIDI PROGRAM CHANGE message.Rear Panel FeaturesThe rear panel of the Anniversary amplifier is the most comprehensive that we have ever produced. Inaddition to the connection and control facilities there are a number of major innovations that directly affect the sound and performance of the amplifier. As your sound is personal to you, it is important to try thedifferent options for the most suitable settings for your style.34. Footswitch Socket Accepts the connecting lead from the three way channelswitching footswitch (which is included with your unit).35. MIDI-In Socket For connection from an external MIDI device.36. Balanced Compensated XLR OutputBalanced output featuring Marshall line level SpeakerEmulation for accurate sound reproduction directly throughrecording equipment or PA (see operational note C).37. Compensated Output Level ControlProvides volume level control of the signal from item (36).Operational Note C: Speaker EmulationThe Marshall speaker emulation circuit provides a signal for direct connection to PA or recording mixers, that retains the true character of the amp driving a cabinet. The quality of this emulation is so high that ‘miking up’ cabinets should no longer be necessary, saving you both time and money, and guaranteeing you a great direct guitar tone.This output is active even when the power amp mute switch (item 39) is activated. Although this power amp mutingallows the amp to be used without speaker cabinets as with all valve amplifiers, it is wise to keep the cabinet connected.38. Uncompensated Line Output Line Out suitable for linking to further amplifiers to extendthe system.39. Uncompensated Link Selection SwitchWhen pushed in, this switch mutes the internal poweramp allowing operation as a pre-amp, switching in alsoactivates the line input to the power amp.40. Line Input Line level input jack to take an external pre-amp thususing just the power stage of your amplifier.Operational Note D: Series effects optionItems 38 & 40 can also be used as a 2nd series effects loop (See operational note F). The selection switch (Item 39) will switch the loop in or out of the circuit, but will not mute the power amp.41. Effects Send Trim Channel 1 Provides -10 to +4db level control of the effects sendfrom Channel 1 only.42. Effects Send Trim Channel 2Provides -10 to +4db level control of the effects sendfrom Channel 2.Operational Note E: Effects level balancingOn 41 & 42 - When setting up the effects loop, the effects processor’s level controls should be set up against the lead channel -3 and matched using switch (44), then channels 1 & 2 set up via the trim controls for an effects send balance.If desired, more or less sound level can be set for differing amounts of effected signal.543. Series/Parallel Selection Switch Selects series or parallel effects loop operation. Seriesconnection is most suitable for Graphic Equalizers,compressor limiters etc. Parallel connection suits delay,reverb and chorus effects. It is generally not advisableto link distortion effects through the loop. Operational Note F: Effects LoopThe main effects loop on this amplifier can be configured either as a series or a parallel loop by using theseries/parallel selection switch (item 43). The parallel loop (switch out) splits the pre-amp signal into two, retaining the direct signal within the amplifier itself, whilst sending a parallel signal out to the effects processor. By turning the direct signal within the processor to zero only an effects signal is returned to the amplifier where it will be mixed back in with the direct signal. This leaves the original direct signal uncoloured by any circuitry within the processor. By using the effects level control (item 28) your ideal mix of dry and effects signal can be easily set up.The series loop (switch in) diverts the whole pre-amp signal through the effects loop and switches off the internal direct signal. The effects level control (28) now acts as an overall master level control.In terms of application, units that are time based (eg Chorus, Delay, Reverb etc) are best suited to the parallel loop. Real time effects (eg. Graphic or Parametric EQ, Compressors etc.) suit series loop operation.It is worth noting that the line in (40) and line out (38) circuit could be used as a series effects loop at 0 dBm, giving you the ability to use both types of loop simultaneously.44. Loop Level Selector Switch Selects the general level of the effects loop (-10 or+4dB) to match processor linked to (45 & 46)45. Effects Send Jack Output for connection to the input of an externaleffects processor.46. Effects Return Jack Input for connection from the output of externalprocessor.47. Damping Select Switch Three position switch to select high, low or autodamping positions. (See operational note G). Operational Note G: Damping ControlThis unique feature controls the power amp damping. Effectively this is the way that the amplifier drives the speaker. High damping gives tight speaker movement and is ideal for clean sounds, where a precise and defined response gives sweet clear picked notes and chords.Low damping, with greater speaker movement, suits breathing heavy overdrive and full distortion. In the auto position the amp automatically selects high damping for clean selections and low damping for crunch and lead. It is probably best to leave the amplifier in auto mode for normal use.48. Power Selection Switch Two position switch to select high power (all 4 valvesworking) or low power (2 valves working). The amplifiermust be switched to standby before selection.(Seeoperational note H).Operational Note H: Power selectionThis useful feature gives excellent flexibility for all playing situations. When switched to half power, with only 2 valves working, these two valves will be driven harder than normal and will therefore have a shorter working life. If a low power selection is required for long periods then it would be better to use the pentode/triode switch (Item 52). ‘Triode’operation will give a slightly different tone to half power. 4 valves give 100 Watts in pentode - 50 Watts in triode. 2 valves give 50 Watts in pentode - 25 Watts in triode.649. Output Fuses With LED Fail IndicatorsIn the event of valve failure the HT fuse will blow toprotect the amplifier from damage. The LED will indicatewhich valve pair is faulty. The Marshall “Failsafe” circuitallows the amplifier to continue running on two valves(providing it is not switched to half power), to get you tothe end of the gig.50. Loudspeaker Outputs Twin loudspeaker output jacks. It is important that thespeakers used are correctly wired and that the impedanceis correctly selected. Also ensure that the speakers arecapable of handling the full power of the amplifier. Thecabinet must be connected before switching on the standbyswitch.51. Impedance Selector Switch Selector to ensure correct match of cabinet impedanceto the amplifier (see impedance chart on page.9).52. Pentode/Triode Selection Switch“Triode” operation gives half the rated power output(Triode operation also gives a smoother tone) and“Pentode” operation provides full rated output. (Seeoperational note I).Operational Note I: Pentode/triodeThis feature is particularly useful when tailoring your system to suit different sized venues and recording applications. When switching this function the standby switch should always be switched off. The same also applies to items 39, 44, 47, 48 & 51.53) Mains Input & Fuse Socket for connection from the mains. Always ensurethat the fuse matches the labelling on the amplifier’srear panel. If you have any doubts contact your dealeror a qualified technician.7Footswitch OperationThe three way footswitch provided with your Anniversary amplifier is for channel switching between the three channels. Connection should be made to the DIN connector on the rear panel of the amp. An LED above the switch corresponds to the channel which has been selected. Switching can also be achieved via MIDI. (See operational note B).Speaker ConnectionThe type of cabinet and speakers has a fundamental effect on the quality of your sound. Also vitallyimportant is the matching of speaker impedance to the amplifier. Incorrect matching will impair theperformance and eventually damage the amplifier.Impedance is usually marked on the cabinet input socket. If you have any doubts, have the speakerschecked by a qualified technician. When using a single cabinet the amp and cabinet should be identical(e.g. 16 Ohm 4x12 cab = 16 Ohm amp selection). If two 16 Ohm cabinets are used, then the amplifiershould be switched to 8 Ohms. Where two 8 ohm cabinets are employed the amp should be switched to4 Ohms. A speaker load below 4 Ohms cannot be used. Following these simple rules should maintainlong life and minimise amplifier servicing requirements. Unlike solid state amps, valve amplifiers don'tincrease in power as speaker impedance is lowered.Operational Note J: Impedance switchingIt should be noted that although the output transformer has 3 impedance connections, only two are switchable from outside the amplifier. These are 16 ohm and 8 Ohm on heads and 8 Ohm and 4 Ohm on combo’s. If your particular application requires this to be different, the transformer connections can easily be altered by a qualified technician.Marshall Cabinet ChartIn some cabinets the speaker type may vary (refer to rating plate for correct impedance).8 Except in US8Trouble Shooting GuideIf you have a problem with your amplifier, it is always best to let a fully qualified approved techniciancheck it over. Regular servicing should prevent any major breakdowns and is an extremely beneficial long term precaution.Often it is the simplest thing that needs attention and it may not be possible to get technical assistance. In this case you may be able to keep the amp running at least until the end of the show. The greatest care should be taken, before removing the back panel, that all mains power is disconnected. Also remember that even after short periods valves will become very hot.Phase splitter9The following list outlines some of the most obvious problems and causes.PROBLEM/SYMPTOM/CUREValves And Pilot Light On, But No Sound.1.Check valve fuse fail lights to see if HT fuses are blown. If they are, replace them with the same valuefuse. If they blow again replace all the power valves if possible.2.Check standby switch.3.Check that the series/parallel switch and power amp mute switch are both out, unless their operation isintended.Constantly Blows HT Fuses.Check the output valves; If they need replacement use matched sets and replace all power valves if possible.Have a service centre check the bias on the output valves. If it’s too low the amp will not clean up. If it’s too high it will stay too clean no matter how loudly you play.High Pitched Whistle At Hi Gain SettingsMost likely this is a microphonic pre-amp valve. Replace if necessary.Rattling Noise From Head Or Chassis99% of the time this is caused by the spring output valve retainers jangling against the valve. Gently bend the spring holders out a fraction.No Sound, Lights, Hum, Etc.1. Check mains fuse, but never with the amp plugged in.2. Make sure the amp is plugged in.Quick HintSomeday, probably at a most inconvenient time, you will blow a fuse or your valves will go. This is noreflection on any amp, valves have a definite lifespan. Always make sure you have replacements, just like you carry spare strings, or you could be left stranded. Always thoroughly check speaker leads to ensure that (A) they are properly connected and (B) they are fully working. Also, use good quality guitar leads and check them regularly.Spares And AccessoriesSuperb engineering is a part of Marshall tradition and your amplifier is built to withstand the abuse of a working musicians heaviest demands. However it is worth remembering that at it’s heart, your amplifier is full of electrical components and glass bottles. If you think of it as an extension to your guitar and treat it accordingly, then long life and small service bills should be the norm. Using only Marshall valves asreplacements will give you optimum performance from your amplifier and will remove the need for any re-biasing by a technician.In the event of component damage Marshall agents worldwide maintain a stock of spares and accessories capable of refurbishing your road-worn beast!10。
