简介

本文档介绍在两个EHWIC-4SHDSL-EA模块之间实施背对背多速率对称高速数字用户线路(G.SHDSL)连接所需的配置步骤。

您必须在中心办公室(CO)模式下配置连接的一端，在客户端设备(CPE)模式下配置连接的另一端，以启用SHDSL连接。这种背对背SHDSL连接设置通常在园区网络中实现，以便在两栋建筑之间提供连接，而无需在两个DSL路由器之间设置数字用户线路接入复用器(DSLAM)。

先决条件

要求

Cisco 建议您了解以下主题：

EHWIC-4SHDSL-EA模块
固定集成多业务路由器(ISR)G2路由器（如C888EA-K9）在Cisco IOS®软件15.2(2)T2及更高版本的CO和CPE模式下均可工作

使用的组件

本文档不限于特定的软件和硬件版本。

但是，设置是使用以下设备构建的：

加载了Cisco IOS® 15.4.3M2的两台ISR第2代路由器(CISCO2901/K9)
两台ISR G2路由器上都安装了两个EHWIC-4SHDSL-EA模块
ANSI/TIA/EIA-568-B电缆，两端均带RJ-45连接器

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

在此设置中，您将使用安装了EHWIC-4SHDSL-EA模块的相同路由器。名为CO_Router的设备配置了SHDSL控制器以在CO模式下运行，而名为CPE_Router的设备配置了SHDSL控制器以在CPE模式下运行。

EHWIC-4SHDSL-EA模块可以配置为第一英里(EFM)以太网和异步传输模式(ATM)以太网。本文档说明如何在EFM和ATM模式下设置背对背SHDSL连接。

此处的示例显示如何在ATM模式下设置背对背SHDSL连接。

ATM模式

在配置背对背SHDSL连接时，可以实施IP over ATM(IPoA)或PPP over ATM(PPPoA)解决方案。

使用本部分可确认配置能否正常运行。

1.要验证路由器是否处于CO模式，请运行show命令。输出中的CO终止行（示例中粗体）表示路由器处于CO模式。默认模式为CPE。为简单起见，有些输出不显示在此处。
