O conjunto de documentação deste produto faz o possível para usar uma linguagem imparcial. Para os fins deste conjunto de documentação, a imparcialidade é definida como uma linguagem que não implica em discriminação baseada em idade, deficiência, gênero, identidade racial, identidade étnica, orientação sexual, status socioeconômico e interseccionalidade. Pode haver exceções na documentação devido à linguagem codificada nas interfaces de usuário do software do produto, linguagem usada com base na documentação de RFP ou linguagem usada por um produto de terceiros referenciado.

Este documento descreve as etapas de configuração necessárias para implementar uma conexão back-to-back Multirate Symmetric High-Speed Digital Subscriber Line (G.SHDSL) entre dois módulos EHWIC-4SHDSL-EA.
Você deve configurar uma extremidade da conexão no modo Central Office (CO) e a outra extremidade no modo Customer Premises Equipment (CPE) para ativar a conexão SHDSL. Esse tipo de configuração de conexão SHDSL back-to-back é normalmente implementada em uma rede de campus para fornecer a conectividade entre dois prédios sem a necessidade de um Multiplexador de Acesso de Linha de Assinante Digital (DSLAM - Digital Subscriber Line Access Multiplexer) entre os dois roteadores DSL.
A Cisco recomenda que você tenha conhecimento destes tópicos:
Este documento não se restringe a versões de software e hardware específicas.
No entanto, a configuração é construída com estes dispositivos:
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
Nessa configuração, você usará roteadores idênticos com módulos EHWIC-4SHDSL-EA instalados neles. O dispositivo chamado CO_Router tem o controlador SHDSL configurado para operar no modo CO, enquanto o dispositivo chamado CPE_Router tem o controlador SHDSL configurado para operar no modo CPE.
O módulo EHWIC-4SHDSL-EA pode ser configurado para Ethernet no First Mile (EFM) e no Asynchronous Transfer Mode (ATM). Este documento explica como configurar a conexão SHDSL back-to-back nos modos EFM e ATM.
O exemplo aqui mostra como configurar a conexão SHDSL back-to-back no modo ATM.
Você pode implementar a solução IP sobre ATM (IPoA) ou PPP sobre ATM (PPPoA) ao configurar a conexão SHDSL back-to-back.

Use esta seção para confirmar se a sua configuração funciona corretamente.
1. Para verificar se o roteador está no modo CO, execute o comando show. A linha de terminação CO na saída (em negrito no exemplo) indica que o roteador está no modo CO. O modo padrão seria CPE. Algumas das saídas não aparecem aqui, para ser breve.
