目录


简介

这个配置包括带有一个主速率接口(PRI) 的Cisco AS5400,支持23个调制解调器呼叫或ISDN呼叫,这取决于主机拨出或拨入。配置有四个 PRI 以允许异步和 ISDN 出站连接。我们已在每个 ISDN 或异步连接的拨号端上配置了静态拨号程序映射。我们正在连接两端使用静态IP路由,以避免不必要的动态路由协议开销。要添加远端位置,必须在拨号端的为新目的地添加拨号映射 、用户名和静态路由。所有的远程节点都有固定的 IP 地址。

注意: 本文档不涉及 AS5350 或 AS5400 系列路由器上的传入调制解调器呼叫和 ISDN 呼叫。有关部门这方面的更多信息,请参见为流入异步呼叫和ISDN呼叫配置AS5350/AS5400的章节。

先决条件

要求

在尝试此配置前,请保证您符合这些要求:

  • 请确保电信公司提供了用于拨出同步和异步的 ISDN PRI 电路。

使用的组件

本文档中的信息基于以下软件和硬件版本:

  • 运行Cisco IOSï ¿  ½软件版本12.2(6)的AS5400

  • 一个有效的 T1 PRI

  • 运行端口件 0.6.108.0 的 Nextport 调制解调器

因为此配置只是实现基本的模拟和ISDN拨入,AS5350和AS5400支持的任何Cisco IOS软件版本都足以满足需求。要运行其它功能,参考软件建议工具选择IOS版本和特性组适当为您的需要。

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。

相关产品

该配置还可应用于 AS5350 或 AS5400 接入服务器。

可以对该配置进行修改以与 E1 PRI 端口一起使用。为E1控制器配置Telco提供的线性编码、成帧及其他物理特性。D信道配置(E1的接口串行x:15)和这里显示的类似。

该配置非常类似于用于拨出访问的 AS5200 或 AS5300 配置。请参阅文档 AS5300 以 ISDN/异步方式拨出(出站 DDR)。两者之间唯一的主要变化是在AS5350或AS5400中,使用命令dial-tdm-clock priority number t1_slot/port用来分配T1时钟优先级。

还可以对该配置进行修改以支持传入和传出呼叫。如需了解更多信息,请参见“在同一条T1/E1 PRI 电路上配置拨入和拨出”文档。

验证

本部分所提供的信息可用于确认您的配置是否正常工作。

命令输出解释程序工具仅限注册用户)支持某些 show 命令,使用此工具可以查看对 show 命令输出的分析。

  • show isdn status - 状态应为:

    layer 1 = active 
    layer 2 = MULTIPLE_FRAMES_ESTABLISHED
    

    如果第 1 层无效,接线适配器或端口可能出现故障或未插入。如果第 2 层处于“TEI_ASSIGNED”状态,则路由器未与交换机通信。有关详细信息,请参阅 T1 PRI 故障排除文档。

  • show isdn service - 用于检查 B 通道的状态。每个呼叫都应有一个繁忙状态的信道。

  • show caller - 显示特定用户的参数,例如分配的IP地址、点对点协议(PPP)、PPP捆绑参数等。如果您的Cisco IOS版本软件不支持此指令,请使用show users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。

故障排除命令

命令输出解释程序工具仅限注册用户)支持某些 show 命令,使用此工具可以查看对 show 命令输出的分析。

注意: 在发出 debug 命令之前,请参阅有关 Debug 命令的重要信息

如下所示,在全局配置中配置时间戳:

service timestamps debug datetime msec 
service timestamps log datetime msec 

使用下列命令排除故障:

  • debug dialer - 在接口中启用按需拨号路由 (DDR) 时,该命令可以显示有关任何呼叫原因(称为拨号原因)的信息。

  • debug isdn q931 - 用于检查作为出站呼叫的 ISDN 连接是否启动。

  • debug ppp negotiation - 用于查看客户端是否通过 PPP 协商。大量的并发 PPP 协商可能会使路由器 CPU 过载。

  • debug ppp authentication -看见客户端可以是否通过认证。

  • debug ppp error - 显示和PPP连接协商与操作相关的协议错误以及统计错误。

对于调制解调器故障排除,请使用下列命令:

  • debug modem - 用于查看路由器从调制解调器接收的信号是否正确。

  • debug modem csm - 用于启用调制解调器管理呼叫交换模块 (CSM) 调试模式。

如需了解nextport命令的更多信息,请参见Cisco AS5400通用网关的管理端口服务章节。
