为流入的多链路异步和ISDN呼叫配置带PRI的访问服务器
简介
在许多环境中，您需要配置接入服务器，该服务器可以接受来自异步和ISDN用户的来电。然后，这些用户可以无缝地连接到网络，就像他们实际存在一样。此类设置通常用于为出差和远程工作人员的用户以及小型办公室 — 家庭办公室(SOHO)站点提供网络连接。
本文档介绍如何配置接入服务器以接受ISDN T1 PRI电路上的传入异步和ISDN呼叫。该配置提供了网络接入服务器(NAS)接受呼叫所需的最低设置。您可以根据需要向此配置添加其他功能。
先决条件
要求
本文档没有任何特定的要求。
使用的组件
本文档中的信息基于以下软件和硬件版本：
-
带有192个MICA调制解调器和8个运行Cisco IOS®软件版本12.2(5)的T1端口的Cisco AS5300。
-
两个T1 PRI。
-
运行Microsoft Windows的PC。此PC具有模拟调制解调器和到公共交换机电话网络的电话连接。PC拨打连接到AS5300的T1 PRI。
-
Cisco 800和1600系列路由器，带ISDN BRI电路。这些路由器是ISDN拨入客户端。提供Cisco 1600的配置。您可以将此客户端配置应用到具有BRI接口的任何路由器。
-
本地身份验证、授权和记帐(AAA)。 如果您有AAA Radius或Tacacs+服务器，则可以使用其中任一服务器为传入呼叫提供AAA。
注意：Cisco 800路由器的配置与Cisco 1600路由器的配置类似，本文档不包括此配置。
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
您可以将此配置与具有T1或PRI卡和内部数字调制解调器（例如MICA、NextPort或Microcom）的任何路由器配合使用。 任何带有T1或PRI卡和数字调制解调器的AS5xxx系列路由器都可以使用此配置中的概念。
Cisco 2600系列路由器不支持内部数字调制解调器。如果路由器具有T1或PRI WIC或网络模块，您可以将Cisco 2600系列路由器配置为仅接受ISDN呼叫。
Cisco 3600系列路由器可同时支持ISDN和调制解调器呼叫。但是，Cisco 3600系列路由器需要T1或PRI WIC或网络模块以及NM-xDM数字调制解调器网络模块。
您还可以修改此配置与E1或PRI端口配合使用。为E1控制器配置Telco提供的线路编码、成帧和其他物理特性。D通道配置（E1的接口Serial x:15）与本文档所示的配置类似。

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 — 确保路由器与ISDN交换机正确通信。在输出中，确保第1层状态为ACTIVE,并且显示第2层状态= MULTIPLE_FRAME_ESTABLISHED。此指令也显示活动的呼叫的数量。有关详细信息，请参阅使用 show isdn status 用于 BRI 故障排除。
-
show ppp multilink — 显示有关活动多链路捆绑的信息。使用此指令验证多链路连接。
-
show dialer [interface type number] — 显示为DDR配置的接口的常规诊断信息。如果拨号器正常运行，则必须显示“拨号器状态为数据链路层运行”消息。如果物理层显示为up，则表明线路协议已启用，但网络控制协议(NCP)没有。启动拨号的数据包的源地址和目标地址显示在 Dial reason line 中。此show命令也显示计时器的配置和连接超时前的时间。
-
show caller user username detail — 显示特定用户的参数，例如分配的IP地址、PPP和PPP捆绑参数。如果您的Cisco IOS软件版本不支持此命令，请使用show user命令。
-
show dialer map - 显示已配置的动态和静态 dialer map。您可以使用此命令检查是否创建了动态拨号器映射。如果没有 Dialer Map，则无法路由数据包。
