Bulb Questions∙What types of bulbs can be used with Decora Digital Controls?DDMX1 Dimmable LEDs, dimmable CFLs, incandescent, halogen,Mark10® Powerline, MLVDDL06 Dimmable LEDs, dimmable CFLs, incandescent, halogenDDS15 LED, CFL, incandescent, fluorescentDDE06 ELV, Dimmable LEDs, dimmable CFLs, incandescent, halogenDD710 0-10V LED/Fluorescent BallastsLeviton recommends only LED and CFL bulbs that are labeled as DIMMABLE be used with theDecora Digital Dimmers. The packaging on the bulb should identify it as dimmable.∙Will I save energy if I dim LED and CFL bulbs?Yes, dimming any bulb reduces energy consumption and is the perfect way to set the ambiancefor any occasion. Below is an example of the energy savings* realized when you dimincandescent, dimmable LED or dimmable CFL bulbs.* Energy savings may vary.∙What makes dimming a dimmable LED/CFL bulb different than dimming an incandescent bulb?Dimmable LED and CFL bulbs contain electronic circuitry not present in incandescent bulbs.Therefore, it is difficult to achieve the same smooth start and complete dimming range as onesees with incandescent bulbs. The Decora Digital Dimmer is designed to interact with theelectronic circuitry, providing smooth low level dimming on the majority of bulbs by majormanufacturers.∙Are there any adjustments that will need to be made to the Decora Digital Device based on the bulb I choose?Decora Digital Devices are preset to the following bulb types:DDMX1: Incandescent/MLV modeDDL06: Incandescent modeDDE06: Electromagnetic Low Voltage (ELV) modeDD710: There are no bulb options; this dimmer can only control 0-10V fixturesDDF01: There are no bulb options; this device can only control a ceiling fanDDS15: There are no bulb optionsIf your Decora Digital Dimmer is controlling a different bulb type, you should set the device tothe proper type of bulb you are controlling via the Decora Digital Dimmer & Timer App:Advanced Setting / Bulb Options.Dimmable CFL bulbs may also require an additional “kick start*” or automatic adjustment toturn on. In this case, the dimmer will need to be set to CFL mode. Please refer to the instructionsheet for details.∙Can I use dimmable LED bulbs when the dimmer is set to CFL mode?This is perfectly acceptable, especially if you encounter LED bulbs that are difficult to start at alow preset dimmer level. In CFL mode the dimmer will provide increased energy or a“kick start*” to start the bulb.∙My dimmable LED/CFL bulbs do not turn on when at the lowest dimmer setting. What can I do?The dimmer features a “kick start*” feature that provides an additional energy boost for hard tostart bulbs. Simply set the load type to the bulb you are currently using via the app to activatethis mode. Also, some bulbs have wider dimming ranges than others. In order to takeadvantage of the full dimming range of the bulb, use the app to adjust and set the minimumlight level.* “Kick start” is a precise boost of energy applied to difficult to start CFLs to initiate smooth start up and preventflickering. This feature maximizes the usable dimming range by allowing the user to start at the lowest possibledim/bright bar position.∙I have some LED bulbs that seem to have a slight delay before they turn on, is this to be expected?It may depend on the bulb. If the dimmer is programmed to have the soft on and off featureenabled, which fades the lights on and off as opposed to abruptly turning them on like a regularswitch, there could be a slight delay before some bulbs will turn on. While most will operatefine with the soft on and off and changes to dimmer settings, some bulbs have a built in delayduring those events and it may take a moment before they will turn on or respond to changesin dimmer settings.∙What will happen if I mix bulb types with the Decora Digital Dimmer?It is strongly recommended that the same light source be used to achieve consistentperformance from bulb to bulb. Keep in mind that different LED bulbs may have different colortemperatures and dimming ranges. If you choose to mix bulb types on the same dimmer it ispossible that you will experience a variation in dimming performance and start upcharacteristics.Device De-rating and Maximum Bulb Wattage∙Is de-rating required when installing more than one Decora Digital device in the same wallbox?If you install more than one device in the same wallbox, you may need to de-rate or reduce theload that each device can control. De-rating may be necessary based on the type of bulb youare controlling. Incandescent and Magnetic Low Voltage bulbs require de-rating. De-rating isnot required when using dimmable LED or dimmable CFL bulbs in multi-dimmer installations.Refer to the de-rating chart in the instructions for maximum load per dimmer.LOAD ONE DEVICE TWO DEVICESMORE THAN TWO DEVICESIncandescent 1000W 800W 700W Magnetic LowVoltage1000VA 800VA 700VALOAD ONE DEVICE TWO DEVICESMORE THAN TWO DEVICESIncandescent 600W 500W 500WLOAD ONE DEVICE TWO DEVICESMORE THAN TWO DEVICESIncandescent 600W 500W 400W Electronic LowVoltage600W 500W 400WONE DEVICE TWO DEVICESMORE THAN TWO DEVICES1.5A 1.5A 1.5ALOAD ONE DEVICETWO DEVICESMORE THAN TWO DEVICESIncandescent 480W 400W 320W Electronic LowVoltage480W400W320WVolts RATING ONE DEVICE TWO DEVICESMORE THAN TWO DEVICES120V 950VA 760VA 760VA 760VA 277V1350VA1080VA1080VA1080VA。

CHP Max Headend Optics Platform CHP-OPTSWITCH-2-L

DATA SHEET CHP Max Headend Optics Platform CHP-OPTSWITCH-2-L Dual Optical A/B SwitchThe CHP Max optical switch provides operators with a reliable and rapid response to changing network conditions, enabling them to proactively identify and fix problems before they impact subscribers. Cable operators can expect a reliable and rapid response to changing network conditions with the CHP Max optical switch design that leverages the installed base of CHP Max5000®chassis, preserving deployed capital. Each channel of the Optical Switch Module accepts two optical signals (“A,” the primary path, and “B,” the backup path). The unit’s microcontroller continuously monitors each fiber’s optical signal power level and the adjustable optical trip threshold for each path. Operators can configure the optical switch in Automatic or Manual Switch Mode. When configured for Automatic Switch Mode, the optical switch will automatically switch to the backup fiber path if the primary path falls below the optical switch threshold that is set by the operator.When optical power is restored to the primary path, the switch willautomatically switch back to the primary path. When placed in ManualSwitch Mode, the optical switch will remain on the path selected by theoperator until the operator selects the other path or returns the unit toAutomatic Switch Mode. Operators can select Automatic and ManualSwitch Mode by using the unit’s front ‐panel pushbutton switch,through the SNMP, or via CORView EMS.•High density to reduce footprint with a dualdensity, single slot unit with 2 independentswitches•Improve network services and customer Qualityof Experience (QoE) with redundant rings androute diversity•Very low power with less than 1 Watt typicalconsumption•Automatic and manual switching using frontpanel pushbutton or remotely through theSNMP or CORView ™Element ManagementSystem (EMS) FEATURESNetwork DiagramOPERATIONAL REQUIREMENTSSMMSMM ‐2 only CMMNo CHP Craft SoftwareNo CHP CORView/CORView LiteV3.5 or later Auto Configuration Supported NoSPECIFICATIONSSpecificationPhysicalDimensions 11.25 in W x 3.4 in H x 18.5 in D (3.2 cm x 8.7 cm x 47.0 cm)Weight2.5 lb (1.3 kg)Optical Connector TypeLC/APC EnvironmentalOperating Temperature Range 20°to 50°C (32°to 122°F)Storage Temperature Range‐40°to 70°C (‐40°to 158°F)Humidity85% non ‐condensing (max)OpticalOperating Wavelength Range1260–1610 nm Input Optical Power Range‐20 to +20 dBm Insertion Loss< 2 dB Optical Crosstalk> 50 dB Optical Return Loss> 45 dB SwitchingSwitching Time< 20 ms Switch TypeLatching, Opto ‐Mechanical Optical Switching Threshold Ranges‐20 to +18 dBm Restore Time0 to 10 minutes in 1 second increments Power RequirementsPower Consumption1 W (Typical), <2 W (max)NOTES:1.Includes handles and connectors.2.Temperature measured at optical switch’s module’s air inlet.ORDERING INFORMATIONCHP‐OPTSWITCH‐2‐L CHP Dual Dense Optical Switch LC/APCRELATED PRODUCTSCHP Chassis Optical Patch CordsPower Supplies Optical PassivesControl Module Installation ServicesContact Customer Care for product information and sales:•United States: 866‐36‐ARRIS•International: +1‐678‐473‐5656Note: Specifications are subject to change without notice.Copyright Statement:©2022CommScope,Inc.All rights reserved.ARRIS,the ARRIS logo,CHP Max5000,and CORView are trademarks of CommScope,Inc.and/or its affiliates.All other trademarks are the property of their respective owners.No part of this content may be reproduced in any form or by any means or used to make any derivative work(such as translation,transformation,or adaptation)without written permission from CommScope, Inc and/or its affiliates(“CommScope”).CommScope reserves the right to revise or change this content from time to time without obligation on the part of CommScope to provide notification of such revision or change.1514620 _CHP Optical Switch_DS_RevA。

7号信令网关资料

第一章基础知识此部分着重介绍了七号信令TUP部分的基础知识，ISUP，SCCP部分的基础知识请参阅相关书籍。

1.1 什么是数字中继数字中继是一个E1接口（又称PCM），是一对引自程控交换机的同轴电缆线，在电缆线上数据传输速率是2.048 Mbps，可以同时容纳32时隙*64Kbps的语音数据。

64,000 bps （每个语音通道的速率)x 32 （通道数或者叫时隙数）2,048,000 （E1 速率）当E1用于七号信令时，在32个时隙中，第0时隙被用作帧同步信息，除0时隙外的某一时隙作为公共信令通道（一般为第16时隙），其余30个时隙用作语音通道。

DSIU7100/7200网关使用第16时隙作为公共信令通道。

1.1.1 E1 帧结构在数字中继电路中，数据按字节构成帧(Frame)。

每个帧256个BITS，每个通道一个字节。

如图1.1所示：图1.1 E1帧结构E1 的时隙编号从0到31。

Linux建立VPN后出现807错误怎么办？

Linux建立VPN后出现807错误怎么办？
导读:一些用户在自己的Linux系统中架设了VPN后，却无法连接到VPN，并且系统提示807错误，这个问题该怎么解决呢？今天小编就帮大家解决这个让人无比纠结的问题吧。

解决方法：
在拨接vpn 时，如果出现807 错误，或是其它在确认账号、密码之前出现的错误，如果确定不是自己电脑的问题，你可以用Vi 编辑/etc/sysconfig/iptables，查看這两条规则是否有正确出现在档案里面：
代码如下：
-A INPUT -p tcp -m tcp –dport 1723 -j ACCEPT
-A INPUT -p gre -j ACCEPT
并且这两条规则的位置不能在任何“-A INPUT -j REJECT …” 的规则下面。

若有这种情形，请把它移到“-A INPUT -J REJECT …” 的上方。

保存之后，再重新启动iptables：
代码如下：
service iptables restart
以上就是在Linux架设了VPN后却无法连接上VPN的解决方法了，正在被这个问题所烦恼着的用户，快来试试小编的这个解决方法吧。

链接星晴VPN800错误解决办法

链接星晴VPN800错误解决办法-VPN服务器800错误解决⽅法说明:由于本⽂较长,⼤家可以按CTRL+F,输⼊您连接VPN出现错误的代码进⾏⾃动查找!连接VPN隧道时发⽣“错误800：不能建⽴VPN连接”的原因⼀般有以下⼏个：1.检查配置中的“⽬的地的主机名或IP地址”使⽤的是域名⽽不是IP地址，由于VPN隧道需要定期进⾏维护，我们有可能变更VPN隧道服务器的IP地址，但域名不会改变。

2.您所在⽹络与我们的VPN隧道服务器没有正确的通道，请尝试更换配置中的“⽬的地的主机名或IP地址”，将其调整为我们的登陆服务器IP地址或者域名。

3.临时性故障，多半是由于您使⽤的DNS服务器繁忙⽆法对服务器IP地址或者域名的名字进⾏解析所引起，可以使⽤以下操作：开始->运⾏->打开：cmd->确定，执⾏命令ipconfig /flushdns后再进⾏VPN连接尝试。

4.由于配置异常造成的⽆法连接，虽然⽤户没有做过任何的配置修改，但由于系统内部的故障会导致配置（注册表信息）出现异常，这是Windows系统中常见的问题。

处理⽅法是删除原VPN隧道连接的配置，重新建⽴⼀个新的VPN隧道连接即可。

5.检查连接的安全参数配置与配置要求⼀致。

6.您机器上的防⽕墙规则设置过于严格，导致⽆法对外进⾏连接，请调整或关闭所有防⽕墙再进⾏尝试。

7.如果有安装家庭⽹关的⽤户，也建议重启⼀下家庭⽹关设备。

8.如果排除上述问题依然⽆法解决，请联系VPN技术⽀持。

连接时的出错信息出错信息619号：私设IP或路由器不⽀持ppTp pass through，或是IP地址是私设IP。

出错信息678号：路由器没有通过VPN功能。

出错信息691号：账号或密码不存在。

账号或密码是否正确请确认⼀下。

出错信息769号：指定的服务器连接不上。

服务器地址不正确。

VPN错误806原因：⾄少有⼀个在您的计算机和互联⽹设备的VPN服务器没有配置为“允许GRE协议数据包验证协议47 GRE是允许所有个⼈防⽕墙设备或路由器”。

锐捷交换机命令

一、交换机配置模式介绍交换机配置模式主要有：? 用户模式：此模式只可以简单的查看一些交换机的配置和一些简单的修改。

Switch>? 特权模式：此模式可以查看一些交换机的配置，后面讲述的很多show命令便是在此模式下进行的，还可以对一些简单的设置配置，例如时间。

Switch> enable //在用户模式下输入enable将进入配置模式Switch＃? 全局配置模式：此模式下可以进行对交换机的配置，例如：命名、配置密码、设路由等。

Switch＃configure erminal //特权模式下可以通过config terminal 命令进入配置模式Switch(config)#? 端口配置模式：此模式下对端口进行配置，如配置端口ip等。

Switch(config)#interface gigabitEthernet 1/1 //配置模式下输入interface gigabitEthernet 1/ 1进入到端口g 1/1接口模式。

二、交换机基本配置? 交换机命名：在项目实施的时候，建议为处于不同位置的交换机命名，便于记忆，可提高后期管理效率。

switch(config)#hostname ruijie //ruijie为该交换机的名字? 交换机配置管理密码：配置密码可以提高交换机的安全性，另外，telnet登录交换机的时候，必须要求有telnet管理密码。

switch (config)#enable secret level 1 0 rg //配置telnet管理密码为rg，其中1表示telnet密码，0表示密码不加密switch (config)#enable secret level 15 0 rg //配置特权模式下的管理密码rg，其中15表示为特权密码? 交换机配置管理IPswitch (config)#interface vlan 1 //假设管理VLAN为VLAN 1switch (config-if)#ip address 192.168.1.1 255.255.255.0 //给管理VLAN配置管理IP地址switch (config-if)#no shutdown //激活管理IP，养成习惯，无论配置什么设备，都使用一下这个命令? 交换机配置网关：switch(config)#ip default-gateway 192.168.1.254 //假设网关地址为192.168.1.254，此命令用户二层设备。

Change the untagged VLAN value only if the hubsand switches in your network support the VLAN (802.1Q)standard.11.Click the Apply button.The connection to the wireless controller is terminated because you have changed its IP address.12.Reconfigure your computer with an IP address and subnet maskthat is in the same IP subnet as the wireless controller. Use the new IP address of the wireless controller to log in again.13.Select Configuration > System > DHCP Server. The DiscoveryWizard (see Discover Access Points) requires a DHCP server to discover the access points. If you already have a DHCP server in your network, disable the DHCP server on the wirelesscontroller. Otherwise, configure the DHCP settings for the DHCP server on the wireless controller.14.Click Apply.15.Decide whether to use the basic profile group (suitable for asmall WLAN) or one or more advanced profile groups (suitable for a large WLAN):•Basic. Allows up to eight profiles (16 for dual-band access points), each of which has its own SSID, security, MAC ACL,rate-limiting settings, WMM settings, and so on.a.Select Configuration > Profile > Basic > Radio.b.Configure one or more profiles, each with its SSID andsecurity settings.c.Click the Apply button.•Advanced. Allows up to eight profile groups. Each group includes all the settings that are required to configure a fullyfunctional access point with up to eight security profiles (16 fordual-band access points).a.Select Configuration > Profile > Advanced > Radio.b.Configure one or more profile groups, each with one ormore profiles that have their own SSID and securitysettings.c.Click the Apply button.Note: For extensive information about the configuration options of the wireless controller, including profile groups, see the reference manual.Deploy the Wireless ControllerTo deploy the wireless controller:1.Disconnect the power cord from the wireless controller.2.Disconnect the wireless controller from the computer and place itwhere you intend to deploy it.3.Connect one end of an Ethernet cable to a LAN port on a routeror switch in your network and the other end to the Ethernet port on the front panel of the wireless controller.4.Reconnect the power cord from the wireless controller to an ACpower outlet.The LEDs light as described in Setup the Wireless Controller.Discover Access PointsThe wireless controller manages selected NETGEAR access points. For a list of supported NETGEAR access points, visit the NETGEAR support site.Before attempting to discover access points, familiarize yourself with the access point LEDs:The Discovery Wizard can discover access points that are either in factory default state or already deployed and running. For the Discovery Wizard to discover access points across a Layer 2 network, Layer 3 network (behind a router), or remote access points, the following requirements apply:•Your network must have a DHCP server that has option 43 enabled with the IP address of the wireless controller, or theDHCP server on the wireless controller must be accessible to all access points.•Each access point must have an IP address.•Each access point must have SNMP and SSH enabled (which is the default).•UDP port number 7890 must be unblocked by your firewall.To discover access points:1.Access the wireless controller at the network IP address that youconfigured (see Configure the Basic Settings).2.Select Access Point > Discovery > Discovery Wizard.3.Follow the steps onscreen to discover the access points and reviewthe discovery results.4.Select Access Point > Discovery > Managed AP List. Add theaccess points that you want to be managed by the wirelesscontroller to the Managed AP List.While the access points are converted from standalone mode to managed mode, the following occurs:•The wireless controller pushes management firmware onto the access points.•The access points become DHCP clients and receive an IP address from either the DHCP server in your network or theDHCP server on the wireless controller.•The profiles that you have configured on the wireless controller are pushed onto the access points.Note: For extensive information about the Discovery Wizard and the discovery process, see the reference manual. Troubleshooting TipsYou cannot access the wireless controller at its default IP address (192.168.0.250). Do the following:•Confirm that the computer is connected to the wireless controller.•You might not have restarted the computer with the wireless controller to have TCP/IP changes take effect. Restart thecomputer.•The computer might be set to enable NetBIOS over TCP/IP.Check that TCP/IP is set to use a static IP address of192.168.0.210 and a subnet mask of 255.255.255.0. (The default TCP/IP setting for Windows is to obtain an IP addressautomatically.) Restart the computer.After initial configuration, you cannot access the wireless controller at its network address. Do the following:•Use the ping command to verify the connection.•Verify that the computer and wireless controller are on the same VLAN.•Some of the wireless controller’s default settings might not work with your network. Check the wireless controller’s default settings against the configuration of other devices in your network.SupportThank you for selecting NETGEAR products.
