本產品的文件集力求使用無偏見用語。針對本文件集的目的，無偏見係定義為未根據年齡、身心障礙、性別、種族身分、民族身分、性別傾向、社會經濟地位及交織性表示歧視的用語。由於本產品軟體使用者介面中硬式編碼的語言、根據 RFP 文件使用的語言，或引用第三方產品的語言，因此本文件中可能會出現例外狀況。深入瞭解思科如何使用包容性用語。

關於此翻譯

思科已使用電腦和人工技術翻譯本文件，讓全世界的使用者能夠以自己的語言理解支援內容。請注意，即使是最佳機器翻譯，也不如專業譯者翻譯的內容準確。Cisco Systems, Inc. 對這些翻譯的準確度概不負責，並建議一律查看原始英文文件（提供連結）。

簡介

本檔案介紹在兩個EHWIC-4SHDSL-EA模組之間實作背對背多速率對稱高速數位使用者線路(G.SHDSL)連線所需的設定步驟。

您必須將連線的一端配置為中央辦公室(CO)模式，另一端配置為客戶端裝置(CPE)模式，才能建立SHDSL連線。這種背對背的SHDSL連線設定通常在園區網路中實現，以便在兩個建築物之間提供連線，而不需要在兩個DSL路由器之間設定數字使用者線接入複用器(DSLAM)。

必要條件

需求

思科建議您瞭解以下主題：

EHWIC-4SHDSL-EA模組
固定整合式服務路由器(ISR)G2路由器（如C888EA-K9）在CO和CPE模式下與Cisco IOS®軟體15.2(2)T2和更新版本配合使用

採用元件

本文件所述內容不限於特定軟體和硬體版本。

但是，使用以下裝置構建設定：

兩台裝有Cisco IOS® 15.4.3M2的ISR第2代路由器(CISCO2901/K9)
兩台ISR G2路由器上都安裝了兩個EHWIC-4SHDSL-EA模組
ANSI/TIA/EIA-568-B電纜，兩端均帶有RJ-45聯結器

本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路正在作用，請確保您已瞭解任何指令可能造成的影響。

設定

在此設定中，您將使用安裝有EHWIC-4SHDSL-EA模組的相同路由器。名為CO_Router的裝置配置了SHDSL控制器，以便在CO模式下運行；而名為CPE_Router的裝置配置了SHDSL控制器，以便在CPE模式下運行。

EHWIC-4SHDSL-EA模組可設定為在第一哩(EFM)和非同步傳輸模式(ATM)下的乙太網路。本文說明如何在EFM和ATM模式下建立背對背SHDSL連線。

此處的示例說明如何在ATM模式下建立背靠背SHDSL連線。

ATM模式

設定背對背SHDSL連線時，您可以實作IP over ATM(IPoA)或PPP over ATM(PPPoA)解決方案。
