简介

本文档说明实施T1信道关联信令(CAS)所需的配置。

先决条件

要求

尝试进行此配置之前，请确保满足以下要求：

本文档基于了解数字T1 CAS（强取位信令）在IOS网关中的工作原理。阅读本文档，了解各种类型的CAS信令方法。本文档还用作配置不同类型CAS信令的指南。

在Cisco AS5300路由器中实施E1 R2信令之前，请检查以确保您的Cisco IOS®软件版本与E1模块中的Cisco VCWare兼容。如果版本不兼容，则语音卡中的数字信号处理器(DSP)模块将不会加载，并且不会进行语音信号处理。请参阅Cisco AS5300的Cisco VCWare兼容性矩阵，确保您的版本兼容。

通常，如果Cisco VCW的版本与Cisco IOS软件不兼容，您可以通过输入show vfc slot_number interface命令来看到这一点，如下所示： 

5300#show vfc 1 interface
Rx: in ptr 18, outptr 0
Tx: in ptr 14  outptr  14
0 in hw queue, 0 queue head , 0 queue tail
Hardware is VFC out-of-band channel
Interface : state RESET DSP instance (0x61048284)
dsp_number 0, Channel ID 0
TX outstanding 0, max TX outstanding 0
Received 18 packets, 1087 bytes, 0 giant packets
0 drops, 0 no buffers, 0 input errors
121 bytes output, 14 frames output
0 bounce errors 0

DSP module 1 is not installed
DSP module 2 is not installed
DSP module 3 is not installed
DSP module 4 is not installed
DSP module 5 is not installed

在上述输出中，“DSP module number is not installed”语句显示该模块号的版本不兼容。加载了正确Cisco VCWare版本的DSP模块示例如下所示：

5300#show vfc 1 interface
Rx: in ptr 24, outptr 0
TX: in ptr 15  outptr  15
0 in hw queue, 0 queue head , 0 queue tail
Hardware is VFC out-of-band channel

0 bounce errors 0

TX outstanding 0, max TX outstanding 8
Received 0 packets, 0 bytes, 0 giant packets
0 drops, 0 no buffers, 0 input errors
0 bytes output,  0 frames output
0 bounce errors 0

Slot 1, DSPM 1 (C542), DSP 2, Channel 1
State RESET, DSP instance (0x6191510C)
TX outstanding 0, max TX outstanding 8
Received 0 packets, 0 bytes, 0 giant packets
0 drops, 0 no buffers, 0 input errors
0 bytes output,  0 frames output
0 bounce errors 0

要检查已安装的Cisco VCWare版本，请输入show vfc slot_number version vcware命令，如下所示：

5300#show vfc 1 version vcware
Voice Feature Card in Slot 1:
VCware Version : 4.10
ROM Monitor Version : 1.2
DSPware Version :
Technology :  C542

注意：确保Cisco VCWare技术版本（c549或c542）与已安装的语音功能卡DSP技术(DSPM-542:单密度语音支持，或DSPM-549:高密度语音支持)。

使用的组件

本文档中的信息基于以下软件和硬件版本：

  • 思科AS5300路由器（所有版本）

本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您使用的是真实网络，请确保您已经了解所有命令的潜在影响。

配置

本部分提供有关如何配置本文档所述功能的信息。

注意：使用命令查找工具(仅限注册客户)可查找有关本文档中使用的命令的详细信息。

配置

要在Cisco 2600/3600系列路由器上运行CAS信令，需要高密度语音网络模块(NM-HDV)。

需要在T1控制器（Cisco AS5xxx和2600/3600路由器）上定义命令ds0-group(或cas-group，具体取决于Cisco IOS版本)。

使用以下步骤配置CAS:

  1. 设置连接到专用自动交换机(PBX)或交换机的T1控制器。确保正确设置T1的成帧和线路编码。

    • T1成帧：ESF或SF

    • T1线路编码：B8ZS或AMI

    • T1时钟源：内部或线路

    注意：请记住，不同的PBX对时钟源有不同的要求。

  2. 使用以下命令序列定义AS5xxx平台上的线路信令：

    5300(config)#controller T1 0

5300(config-controller)#
ds0-group 1 timeslots 1-24 type ?

e&m-fgb              E & M Type II FGB
e&m-fgd              E & M Type II FGD
e&m-immediate-start  E & M Immediate Start
fgd-eana             FGD Exchange Access North American
fgd-os               FGD Operator Services
fxs-ground-start     FXS Ground Start
fxs-loop-start       FXS Loop Start
none                 Null Signaling for External Call Control
r1-itu               R1 ITU
sas-ground-start     SAS Ground Start
sas-loop-start       SAS Loop Start
<cr>

    注意：如果要收集T1控制器上的拨号号码识别服务(DNIS)信息，则必须在接入服务器上手动配置该信息。要在控制器T1配置下为E&M-fgb收集双音多频(DTMF)DNIS，请使用ds0-group 0 timeslots 1-24 type e&m-fgb dtmf dnis命令。要为E&M-fgb收集多频(MF)DNIS，请使用ds0-group 0 timeslots 1-24 type e&m-fgb mf dnis命令。

  3. 使用以下命令序列定义Cisco 2600/3600平台上的线路信令：

    3600(config)#controller T1 0
3600(config-controller)# 
ds0-group 1 timeslots 1-24 type ? 

e&m-delay-dial       E & M Delay Dial
e&m-fgd 			 E & M Type II FGD
e&m-immediate-start  E & M Immediate Start
e&m-wink-start       E & M Wink Start
ext-sig              External Signaling
fgd-eana             FGD-EANA BOC side
fxo-ground-start     FXO Ground Start
fxo-loop-start       FXO Loop Start
fxs-ground-start     FXS Ground Start
fxs-loop-start       FXS Loop Start
none                 Null Signaling for External Call Control
<cr>

    在Cisco IOS软件版本11.3中，命令序列如下。

    peggy(config)#controller T1 0

peggy(config-controller)#cas-group 1 timeslot 1-15 type ?

...

    注意：如果从Cisco IOS软件版本11.3升级到版本12.0，则新命令将自动替换旧命令。

故障排除

本部分提供的信息可用于对配置进行故障排除。

故障排除步骤

请按照以下说明排除配置故障。有关故障排除的其他信息，请参阅使用cas-custom命令的E1 R2自定义。

  1. 检验T1控制器0是否已打开。如果它关闭，请检查成帧、线路编码、时钟源、警报、更换电缆、重新拔插卡等。

  2. 如果您使用的是Cisco AS5300，请使用show vfc slot number interface命令检查DSP是否已正确安装。

  3. 对于FGD中继，在普通旧式电话服务(POTS)对等体上配置直接拨入(DID)，以便接收的数字用于选择传出对等体。

    注意：在Cisco AS5300上，您需要配置“dnis”选项以请求DNIS。

  4. 打开下节所示的debug命令，并研究输出

  5. 检查路由器与PBX或交换机之间的通信。

    • 线路被扣了吗？

    • 路由器是否接收/发送数字？

    • 找出哪一方正在清除呼叫。

    • 如果可能，请使用Cisco.com上提供的最新Cisco IOS软件版本。

确定Cisco AS5xxx路由器上的信令

通过查看路由器的调试，很难确定您拥有的信令类型。但是，可以对信号应该是什么进行很好的猜测。以下调试在确定信令类型时相当可靠（尤其是当所有信道都空闲时）。建议您首先通过这些调试验证您的信令，因为它们可以发现最常见且不太明显的调配错误。与往常一样，在路由器中打开调试时请谨慎。建议您不要启用调试，除非您熟悉其功能。请注意，并非所有调试都适用于每个网络接入服务器(NAS)平台。

故障排除命令

命令输出解释程序（仅限注册用户）(OIT) 支持某些 show 命令。使用 OIT 可查看对 show 命令输出的分析。

注意：在使用debug命令之前，请参阅有关Debug命令的重要信息。

  • debug serial interface — 显示串行连接故障的信息。

  • show controller t1 — 显示特定于控制器硬件的控制器状态。

  • debug cas — 用于Cisco AS5xxx平台上的线路信令。

  • debug vpm signal — 用于Cisco 26xx/36xx平台上的线路信令。

  • debug vtsp all — 启用PBX和路由器之间交换的所有消息（数字）的输出。
