Este documento fornece um exemplo de configuração e técnicas de Troubleshooting para sinalização E1 R2 para chamadas de dados.
Antes de tentar esta configuração, é recomendável que você leia o documento Teoria de Sinalização E1 R2. Para obter informações sobre a sinalização E1 R2 para aplicativos de voz, consulte o documento Configuração e Troubleshooting de Sinalização E1 R2.
Esta configuração foi desenvolvida e testada utilizando as versões de software e hardware abaixo. Esta configuração mostra uma configuração de laboratório back-to-back entre um roteador Cisco 3640 e um servidor de acesso Cisco AS5300.
O AS5300 está simulando o cliente e executando o software Cisco IOS® versão 12.2(3).
O 3640 está atuando como um servidor e executando o Cisco IOS Software versão 12.1(10).
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.
Para obter mais informações sobre convenções de documento, consulte as Convenções de dicas técnicas Cisco.
A sinalização E1 R2 permite que um servidor de acesso universal da Cisco converse com troncos de centrais que também usam a sinalização E1 R2. A sinalização R2 é um padrão de sinalização internacional comum a redes E1 canalizadas. Não há um único padrão para a sinalização de R2. A recomendação ITU-T Q.400-Q.490 define R2, mas vários países implementam R2 de maneiras completamente diferentes.
A Cisco Systems lida com esse desafio ao suportar várias implementações localizadas de sinalização R2 em seu software Cisco IOS. A localização personalizada de R2 significa que a sinalização de R2 é suportada para uma ampla variedade de países e regiões geográficas. A Cisco está sempre apoiando as variantes de sinalização E1 R2 em novos países.
Observação: somente os módulos de agregação de canais ISDN (MICA) e modem digital Nextport suportam a funcionalidade R2. Não há suporte a R2 para modems Microcom ou aplicativos que não sejam de modem.
Nesta seção, você encontrará informações para configurar os recursos descritos neste documento. Essa configuração é válida para os seguintes cenários:
Conexões de discagem de modem sobre E1 R2
Conexões E1 R2 back-to-back
Conexões E1 R2 entre o roteador Cisco
Observação: a configuração do controlador E1 é a mesma para chamadas de dados ou voz. A única diferença é:
Para chamadas de dados, você precisa configurar os modems para aceitar as chamadas.
Para chamadas de voz, você precisa configurar as portas de voz para aceitar as chamadas.
Observação: para encontrar informações adicionais sobre os comandos usados neste documento, use a ferramenta Command Lookup Tool (somente clientes registrados).
Este documento utiliza a instalação de rede mostrada no diagrama abaixo.
A configuração de E1 R2 para chamadas de dados envolve duas etapas gerais:
Configuração do E1 R2
Configurando os modems e problemas relacionados
A configuração do E1 R2 é baseada nas informações obtidas da Telco. Consulte o documento E1 R2 Signaling Configuration and Troubleshooting para obter informações adicionais sobre a configuração específica de E1 R2.
A configuração do modem é semelhante à de qualquer servidor de acesso com, por exemplo, uma linha PRI.

A Output Interpreter Tool (somente clientes registrados) oferece suporte a determinados comandos show, o que permite exibir uma análise da saída do comando show.
Observação: antes de emitir comandos debug, consulte Informações importantes sobre comandos debug.
show controllers e1 - exibe o estado do controlador específico ao hardware do controlador. Para obter detalhes, consulte Entendendo o Comando show controllers e1.
show diag - no Cisco 3600, exibe informações de hardware do roteador, verifica se todo o hardware é reconhecido.
debug modem csm - depura o CSM (Call Switching Module) usado para conectar chamadas no modem.
debug cas - fornece rastreamentos em tempo real do status do bit de sinalização CAS.
debug modem - exibe a atividade da linha do modem em um servidor de acesso.
show modem version - exibe informações sobre a versão do firmware do modem, da controladora e do código DSP.
