Na sinalização E&M digital nas plataformas de roteador Cisco 2600, 3600 e MC3810, alguns slots de tempo T1/E1 podem ficar presos no estado EM_PARK. Isso é visível quando você emite o comando show voice call summary. Este documento explica como solucionar esse problema.
Esta saída mostra que alguns slots de tempo estão no estado EM_PARK. Um intervalo de tempo no estado EM_PARK não é usado para chamadas de voz.

No CAS T1, por exemplo, a sinalização de início de piscar, quando o PBX fica fora do gancho, o slot de tempo do lado do roteador/gateway permanece no estado ocioso (EM_ONHOOK) até que a chamada seja atendida por um destino remoto. O estado do slot de tempo do roteador muda para EM_OFFHOOK quando a chamada é atendida pelo destino remoto.
Se a chamada não for conectada, o roteador/gateway reproduzirá os tons de reordenação da banda interna para o chamador. Como o estado do canal no lado do roteador ainda é EM_ONHOOK, o roteador não consegue desligar o canal. Depois que o chamador desligar, o PBX precisa alterar seu estado de canal de fora do gancho para dentro do gancho.
Em alguns casos, os PBXs não enviam as mensagens no gancho, com a ajuda das transições ABCD. O roteador tem uma solução alternativa para isso chamada resposta falsa. Sem a solução de resposta falsa, os canais permanecem em um estado de EM_PARK indefinidamente. Consulte a seção Resposta falsa para obter mais informações.
Observação: as chamadas podem ficar presas no estado EM_PARK em alguns canais T1 se o chassi do roteador do gateway de voz não estiver eletricamente aterrado corretamente. Consulte o guia de instalação de hardware para obter mais informações sobre aterramento elétrico.
Consulte as Convenções de Dicas Técnicas da Cisco para obter mais informações sobre convenções de documentos.
Há dois motivos possíveis, principais, para que o intervalo de tempo fique preso no estado EM_PARK:
O processador de sinal digital (DSP) está com defeito e apresenta problemas de hardware ou software.
O PSTN switch/PBX envia um sinal de desconexão contínuo ao roteador e não o libera.
Estas são as soluções para este problema:
Se os intervalos de tempo no sistema estiverem presos no estado EM_PARK, verifique os DSPs. Consulte Troubleshooting de DSP em NM-HDV para Cisco 2600/3600 Series Routers para verificar os DSPs.
Se os DSPs estiverem vivos, o problema pode estar no lado do PSTN switch/PBX ou no Cisco IOS® (o roteador/gateway não inicia o procedimento de resposta falsa). Consulte a seção Resposta falsa para obter mais informações.
O roteador/gateway da Cisco espera por um valor padrão de 30 segundos (use os comandos timeouts wait-release e timeouts call-disconnect para alterar esses valores) depois de saber que o intervalo de tempo precisa ser definido do PBX para no gancho enquanto ele reproduz o tom de reordenação.
Se isso não acontecer, o roteador move o slot de tempo para o estado EM_PARK e inicia outro temporizador com uma duração de 10 segundos. Se o PBX ainda não entrar no gancho após a duração de 10 segundos, o roteador engana o PBX. O roteador envia uma resposta falsa de um segundo de duração e, em seguida, entra no gancho.
Depois que o roteador envia o sinal de resposta falso, ele inicia outro temporizador de cinco minutos. Se o PBX ficar no gancho, o temporizador pára e o roteador faz a transição do intervalo de tempo para o estado EM_ONHOOK. Caso contrário, após cinco minutos, ele envia outro sinal de resposta falso com uma duração de um segundo. O roteador repete esse processo até que o PBX fique no gancho. O roteador força o PBX a limpar a chamada.
Observação: essa transição de resposta não é atualizada para nenhum registro contábil, pois a chamada real é cancelada. Mas o PBX entende isso como uma resposta e o usuário provavelmente é cobrado pela chamada de duração de um segundo.
Se o DSP associado ao intervalo de tempo no estado EM_PARK estiver ativo e saudável e o problema persistir, execute os comandos debug vpm all e debug vtsp all para ver se o Cisco IOS tenta enviar a resposta falsa.
Observação: você precisa executar as depurações por mais de cinco minutos.
Observação: na maioria dos casos, se o DSP estiver com defeito, o roteador não executa a solução de resposta falsa. Consulte Troubleshooting de DSP em NM-HDV para Cisco 2600/3600 Series Routers para obter mais informações.
Esta saída de depuração mostra como um intervalo de tempo fica preso em EM_PARK e como a solução de resposta falsa funciona.
