Configurando e Troubleshooting de T1 CAS Signaling

Introduction

Este documento explica as configurações necessárias para a implementação do canal T1 associado à sinalização (CAS).

Prerequisites

Requirements

Certifique-se de atender a estes requisitos antes de tentar esta configuração:

Este documento é baseado na compreensão de como o CAS T1 digital (Robbed Bit Signaling) funciona nos gateways do IOS. Leia este documento para entender os vários tipos de métodos de sinalização CAS. Este documento também serve como um guia para configurar os diferentes tipos de sinalização CAS.

Antes de implementar a sinalização E1 R2 em um roteador Cisco AS5300, verifique se sua versão do Cisco IOS® Software é compatível com o Cisco VCWare no módulo E1. Se as versões não forem compatíveis, os módulos do DSP (processador de sinal digital) na placa de voz não serão carregados e o processamento do sinal de voz não ocorrerá. Consulte a Matriz de compatibilidade do Cisco VCWare para o Cisco AS5300 para certificar-se que suas versões sejam compatíveis.

Normalmente, se a versão do Cisco VCWare não for compatível com o Cisco IOS Software, você pode ver isso inserindo o comando show vfc slot_number interface como mostrado aqui:

5300#show vfc 1 interface
Rx: in ptr 18, outptr 0
Tx: in ptr 14  outptr  14
0 in hw queue, 0 queue head , 0 queue tail
Hardware is VFC out-of-band channel
Interface : state RESET DSP instance (0x61048284)
dsp_number 0, Channel ID 0
TX outstanding 0, max TX outstanding 0
Received 18 packets, 1087 bytes, 0 giant packets
0 drops, 0 no buffers, 0 input errors
121 bytes output, 14 frames output
0 bounce errors 0

DSP module 1 is not installed
DSP module 2 is not installed
DSP module 3 is not installed
DSP module 4 is not installed
DSP module 5 is not installed

Na saída acima, as instruções "DSP module number is not installed" mostram que as versões são incompatíveis para esse número de módulo. Um exemplo dos módulos DSP com a versão correta do Cisco VCWare é mostrado aqui:

5300#show vfc 1 interface
Rx: in ptr 24, outptr 0
TX: in ptr 15  outptr  15
0 in hw queue, 0 queue head , 0 queue tail
Hardware is VFC out-of-band channel
Interface : state RESET DSP instance (0x618C6088)

TX outstanding 0, max TX outstanding 8
Received 0 packets, 0 bytes, 0 giant packets
0 drops, 0 no buffers, 0 input errors
0 bytes output,  0 frames output
0 bounce errors 0

Para verificar a versão instalada do Cisco VCWare, digite o comando show vfc slot_number version vcware conforme mostrado aqui:

5300#show vfc 1 version vcware
Voice Feature Card in Slot 1:
VCware Version : 4.10
ROM Monitor Version : 1.2
DSPware Version :
Technology :  C542

Observação: verifique se a versão da tecnologia Cisco VCWare (c549 ou c542) corresponde à tecnologia DSP da placa de recurso de voz instalada (DSPM-542: suporte de voz de densidade única ou DSPM-549: suporte de voz de alta densidade).

Configurar

Nesta seção, você encontrará informações para configurar os recursos descritos neste documento.

Nota:Use a Command Lookup Tool (somente clientes registrados) para obter mais informações sobre os comandos usados neste documento.

Configurações

Para executar a sinalização CAS nos Cisco 2600/3600 Series Routers, um NM-HDV (High Density Voice Network Module) é necessário.

O comando ds0-group (ou cas-group, dependendo da versão do Cisco IOS) precisa ser definido nos controladores T1 (Cisco AS5xxx e 2600/3600 routers).

Use este procedimento para configurar o CAS:

1. Configure o controlador T1 conectado ao PBX (private automatic branch exchange, troca de ramais automática) ou ao switch. Verifique se o enquadramento e a codificação de linha do T1 foram definidos corretamente.

   • Enquadramento de T1: ESF ou SF

   • Codificação de linha T1: B8ZS ou AMI

   • Fonte de tempo T1: interno ou linha

   Observação: lembre-se de que diferentes PBXs têm requisitos diferentes na fonte do relógio.

2. Use esta sequência de comandos para definir a sinalização de linha nas plataformas AS5xxx:

   5300(config)#controller T1 0
   
   5300(config-controller)#
   ds0-group 1 timeslots 1-24 type ?
   
   e&m-fgb              E & M Type II FGB
   e&m-fgd              E & M Type II FGD
   e&m-immediate-start  E & M Immediate Start
   fgd-eana             FGD Exchange Access North American
   fgd-os               FGD Operator Services
   fxs-ground-start     FXS Ground Start
   fxs-loop-start       FXS Loop Start
   none                 Null Signaling for External Call Control
   r1-itu               R1 ITU
   sas-ground-start     SAS Ground Start
   sas-loop-start       SAS Loop Start
   <cr>

   Observação: se quiser coletar informações do DNIS (Serviço de Identificação de Número Discado) em um controlador T1, você deve configurá-las manualmente no servidor de acesso. Para coletar DNIS DTMF (Dual Tone Multifrequency) para E&M-fgb em uma configuração de T1 do controlador, use o comando ds0-group 0 timeslots 1-24 type e&m-fgb dtmf dnis. Para coletar DNIS de multifreqüência (MF) DNIS para E&M-fgb, use o comando ds0-group 0 timeslots 1-24 type e&m-fgb mf dnis.

3. Use esta sequência de comandos para definir a sinalização de linha nas plataformas Cisco 2600/3600:

   3600(config)#controller T1 0
   3600(config-controller)# 
   ds0-group 1 timeslots 1-24 type ? 
   
   e&m-delay-dial       E & M Delay Dial
   e&m-fgd 			 E & M Type II FGD
   e&m-immediate-start  E & M Immediate Start
   e&m-wink-start       E & M Wink Start
   ext-sig              External Signaling
   fgd-eana             FGD-EANA BOC side
   fxo-ground-start     FXO Ground Start
   fxo-loop-start       FXO Loop Start
   fxs-ground-start     FXS Ground Start
   fxs-loop-start       FXS Loop Start
   none                 Null Signaling for External Call Control
   <cr>

   Com o Cisco IOS Software Release 11.3, a seqüência de comandos é a seguinte.

   peggy(config)#controller T1 0
   
   peggy(config-controller)#cas-group 1 timeslot 1-15 type ?
   
   ...

   Observação: se você atualizar do Cisco IOS Software Release 11.3 para Release 12.0, o novo comando substituirá o antigo automaticamente.

Troubleshoot

Esta seção fornece informações que podem ser usadas para o troubleshooting da sua configuração.

Procedimento de Troubleshooting

Siga estas instruções para resolver problemas da sua configuração. Consulte Personalização de E1 R2 com o Comando cas-custom para obter informações adicionais sobre solução de problemas.

1. Verifique se o controlador T1 0 está ativado. Se estiver fora do ar, verifique os quadros, a codificação das linhas, a fonte de tempo, os alarmes, substitua o cabo, reencaixe a placa de linha e assim por diante.

2. Se estiver usando um Cisco AS5300, verifique se os DSPs estão instalados corretamente com o comando show vfc slot number interface.

3. Com relação a troncos FGD, configure direct inward dial (DID) no peer de serviço de telefonia tradicional (POTS) de modo que os dígitos recebidos sejam usados para escolher um peer enviado.

   Observação: no Cisco AS5300 você precisará ter a opção "dnis" configurada para solicitar DNIS.

4. Ative alguns dos comandos de depuração mostrados na seção seguinte e analise as saídas

5. Check for communication between the router and PBX or Switch.

   • A linha está capturada?

   • O roteador recebe/envia dígitos?

   • Descubra que lado está removendo a chamada.

   • Se possível, use as versões mais recentes do Cisco IOS Software disponíveis no Cisco.com.

Determinação de Sinalização em um Roteador Cisco AS5xxx.

Pode ser difícil determinar que tipo de sinalização você tem ao examinar as depurações de um roteador. No entanto, é possível adivinhar bem o que deve ser a sinalização. A depuração a seguir é relativamente confiável (principalmente quando todos os canais estão ociosos) na determinação do tipo de sinalização. Recomenda-se verificar primeiro a sinalização através das depurações de modo que possam captar os erros de provisão mais comuns e não tão óbvios. Como de costume, tenha cuidado ao ativar as depurações no roteador. Convém não habilitar a depuração a não ser que você esteja familiarizado com as suas funcionalidades. Esteja ciente de que nem todas as depurações estão disponíveis para cada plataforma de servidor de acesso à rede (NAS).

Comandos para Troubleshooting

A Output Interpreter Tool ( somente clientes registrados) (OIT) oferece suporte a determinados comandos show. Use a OIT para exibir uma análise da saída do comando show.

Nota:Consulte Informações Importantes sobre Comandos de Depuração antes de usar comandos debug.

• debug serial interface — Exibe informações sobre uma falha de conexão serial.

• show controller t1 — Exibe o status do controlador específico para o hardware do controlador.

• debug cas — Para sinalização de linha em plataformas Cisco AS5xxx.

• debug vpm signal — Para sinalização de linha em plataformas Cisco 26xx/36xx.

• debug vtsp all — Ativa a saída de todas as mensagens (dígitos) trocadas entre o PBX e o roteador.
