En la señalización E/M digital en las plataformas de routers Cisco 2600, 3600 y MC3810, algunas ranuras de tiempo T1/E1 pueden atascarse en el estado EM_PARK. Esto es visible cuando ejecuta el comando show voice call summary. Este documento explica cómo resolver este problema.
Esta salida muestra que algunas ranuras de tiempo están en el estado EM_PARK. No se utiliza una ranura de tiempo en el estado EM_PARK para llamadas de voz.

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.
En T1 CAS, por ejemplo, la señalización de inicio wink, cuando el PBX se desconecta, la ranura de tiempo del lado del router/gateway permanece en el estado inactivo (EM_ONHOOK) hasta que la llamada es respondida por un destino remoto. El estado de la ranura de hora del router cambia a EM_OFFHOOK cuando el destino remoto contesta la llamada.
Si la llamada no se conecta, el router/gateway reproducirá los tonos de reorden dentro de la banda a la persona que llama. Dado que el estado del canal en el lado del router sigue siendo EM_ONHOOK, el router no puede colgar el canal. Después de que la persona que llama cuelga, la PBX necesita cambiar su estado de canal de descolgado a colgado.
En algunos casos, los PBX no envían los mensajes de conexión, con la ayuda de las transiciones ABCD. El router tiene una solución alternativa para esta llamada respuesta falsa. Sin la solución alternativa de respuesta falsa, los canales cuelgan indefinidamente en un estado de EM_PARK. Consulte la sección Respuesta Falsa para obtener más información.
Nota: Las llamadas se pueden atascar en el estado EM_PARK en algunos canales T1 si el chasis del router de gateway de voz no se conecta a tierra de forma eléctrica correctamente. Consulte la guía de instalación del hardware para obtener más información sobre la toma a tierra de la red eléctrica.
Hay dos razones principales posibles por las que la ranura de tiempo está atascada en el estado EM_PARK:
El procesador de señales digitales (DSP) no funciona correctamente y tiene problemas de hardware o de software.
El switch/PBX PSTN envía una señal de desconexión continua al router y no la libera.
Estas son las soluciones a este problema:
Si las ranuras de tiempo del sistema están atascadas en el estado EM_PARK, verifique los DSP. Refiérase a Troubleshooting del DSP en NM-HDV para Cisco 2600/3600 Series Routers para verificar los DSP.
Si los DSP están activos, el problema puede estar en el lado PSTN switch/PBX o en el Cisco IOS® (el router/gateway no inicia el procedimiento de respuesta falsa). Consulte la sección Respuesta Falsa para obtener más información.
El router/gateway de Cisco espera un valor predeterminado de 30 segundos (utilice los comandos timeouts wait-release y timeouts call-disconnect para cambiar estos valores) después de saber que la ranura de tiempo debe configurarse desde el PBX para engancharse mientras reproduce el tono de reorden.
Si esto no ocurre, el router mueve la ranura de tiempo al estado EM_PARK e inicia otro temporizador con una duración de 10 segundos. Si el PBX todavía no se conecta después de la duración de 10 segundos, el router hace un truco con el PBX. El router envía una respuesta falsa de un segundo de duración y luego se conecta.
Después de que el router envía la señal de respuesta falsa, el router inicia otro temporizador de cinco minutos. Si el PBX se conecta, el temporizador se detiene y el router pasa la ranura de tiempo al estado EM_ONHOOK. De lo contrario, después de cinco minutos envía otra señal de respuesta falsa de una duración de un segundo. El router repite este proceso hasta que el PBX se conecta. El router fuerza al PBX a borrar la llamada.
Nota: Esta transición de respuesta no se actualiza a ningún registro de contabilidad, ya que se borra la llamada real. Sin embargo, el PBX lo entiende como una respuesta y es probable que el usuario se cargue por la llamada de un segundo de duración.
Si el DSP asociado con la ranura de tiempo en el estado EM_PARK está vivo y en buen estado y el problema persiste, ejecute los comandos debug vpm all y debug vtsp all para ver si el IOS de Cisco intenta enviar la respuesta falsa.
Nota: Debe ejecutar las depuraciones durante más de cinco minutos.
Nota: En la mayoría de los casos, si el DSP es incorrecto, el router no realiza la solución alternativa de respuesta falsa. Refiérase a Troubleshooting del DSP en NM-HDV para Cisco 2600/3600 Series Routers para obtener más información.
Esta salida de depuración muestra cómo una ranura de tiempo se bloquea en EM_PARK y cómo funciona la solución alternativa de respuesta falsa.
