Configuración de un Servidor de Acceso con PRIs para Llamadas ISDN y Asíncronas Multilink Entrantes
Contenido
Introducción
En muchos entornos, debe configurar un servidor de acceso que pueda aceptar llamadas entrantes de usuarios asíncronos e ISDN. Estos usuarios pueden conectarse perfectamente con la red como si estuvieran presentes físicamente. Esta configuración se utiliza habitualmente para proporcionar conectividad de red a los usuarios que viajan y son teletrabajadores, así como a los sitios de oficinas pequeñas en casa (SOHO).
Este documento describe cómo configurar un Servidor de Acceso para aceptar llamadas ISDN y asíncronas entrantes en circuitos ISDN T1 PRI. La configuración proporciona la configuración mínima necesaria para que el servidor de acceso a la red (NAS) acepte la llamada. Puede agregar funciones adicionales a esta configuración en función de sus necesidades.
Prerequisites
Requirements
No hay requisitos específicos para este documento.
Componentes Utilizados
La información que contiene este documento se basa en las siguientes versiones de software y hardware.
-
Cisco AS5300 con 192 módems MICA y ocho puertos T1 que ejecutan Cisco IOS® Software Release 12.2(5).
-
Dos PRI T1.
-
PC que ejecuta Microsoft Windows. Este PC tiene un módem analógico y una conexión telefónica a la red telefónica pública del switch. La PC se comunica al T1 PRI que está conectado al AS5300.
-
Routers Cisco de las series 800 y 1600 con circuitos ISDN BRI. Estos routers son los clientes de marcado ISDN. Se proporciona la configuración del Cisco 1600. Puede aplicar esta configuración de cliente a cualquier router con una interfaz BRI.
-
Autenticación, autorización y contabilidad locales (AAA). Si posee un servidor Radius AAA o Tacacs +, puede utilizar cualquiera de ellos para abastecer al AAA en las llamadas entrantes.
Nota: La configuración del router Cisco 800 es similar a la del router Cisco 1600 y no se incluye en este documento.
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.
Productos Relacionados
Puede utilizar esta configuración con cualquier router que tenga tarjetas T1 o PRI y módems digitales internos (por ejemplo, MICA, NextPort o Microcom). Cualquier router de la serie AS5xxx con una tarjeta T1 o PRI y módems digitales puede usar los conceptos de esta configuración.
Los routers de la serie 2600 de Cisco no admiten módems digitales internos. Puede configurar los Cisco 2600 Series Routers para que acepten solamente llamadas ISDN, siempre que el router tenga un T1 o PRI WIC o un Módulo de red.
Los routers de la serie 3600 de Cisco pueden soportar llamadas ISDN y de módem. Sin embargo, los routers de la serie 3600 de Cisco requieren un T1 o PRI WIC o un módulo de red y el módulo de red de módem digital NM-xDM.
También puede realizar modificaciones para utilizar esta configuración con puertos E1 o PRI. Configure el controlador E1 con la codificación de línea, el entramado y otras características físicas que su compañía telefónica suministra. La configuración del canal D (interfaz Serial x:15 para E1s) es similar a la que se muestra en este documento.

Verificación
En esta sección encontrará información que puede utilizar para confirmar que su configuración esté funcionando correctamente.
La herramienta Output Interpreter (sólo para clientes registrados) permite utilizar algunos comandos “show” y ver un análisis del resultado de estos comandos.
-
show isdn status: garantiza que el router se comunica correctamente con el switch ISDN. En el resultado, asegúrese de que Estado de Capa 1 sea ACTIVO y que aparezca el Estado de Capa 2 = MULTIPLE_FRAME_ESTABLISHED. Este comando muestra también el número de llamadas activas. Refiérase a Uso del Comando show isdn status para Troubleshooting de BRI para obtener más información.
-
show ppp multilink: muestra información sobre paquetes multilink activos. Utilice este comando para verificar la conexión multilink.
-
show dialer [interface type number]—muestra información de diagnóstico general para las interfaces configuradas para DDR Si el marcador aparece correctamente, el mensaje Dialer state is data link layer up debe aparecer. Si aparece capa física arriba, la implicancia es que el protocolo de línea surgió, pero el protocolo de control de red (NCP) no lo hizo. Las direcciones de origen y destino del paquete que inició el marcado se ven en la línea de motivo del marcado. Este comando show también muestra la configuración del temporizador y el tiempo antes de que la conexión se agote.
-
show caller user username detail: muestra los parámetros para el usuario en particular, por ejemplo, la dirección IP asignada, los parámetros PPP y PPP bundle. Si su versión del software Cisco IOS no es compatible con este comando, utilice el comando show user.
-
show dialer map: muestra mapas de marcador dinámicos y estáticos configurados. Puede utilizar este comando para verificar si se crea un mapa de marcador dinámico. No puede rutear paquetes sin un asociador del marcador.

debug isdn q931: muestra la configuración de la llamada y el desmontaje de la conexión de red ISDN (Capa 3).
-
debug modem: muestra la actividad de la línea del módem en un servidor de acceso. El resultado se muestra cuando la línea del módem cambia de estado.
-
debug modem csm: permite resolver problemas de Call Switching Module (CSM) en routers con módems digitales internos. Con este comando puede realizar un seguimiento de la secuencia completa de la switching de las llamadas entrantes y salientes.
-
debug ppp negotiation: muestra información sobre el tráfico PPP y los intercambios, y negocia el protocolo de control de enlaces (LCP), la autenticación y el protocolo de control de red (NCP). Una negociación PPP exitosa abre primero el estado LCP, luego realiza la autenticación y por último negocia el NCP. Los parámetros de links múltiples como el Maximum Receive Reconstructed Unit (MRRU) se establecen durante la negociación LCP (protocolo de control de links)
-
debug ppp authentication: muestra los mensajes del protocolo de autenticación PPP, incluidos los intercambios de paquetes CHAP y los intercambios del protocolo de autenticación de contraseña (PAP).
-
debug ppp error — Muestra los errores de protocolo y las estadísticas de error relacionadas con la negociación y operación de conexiones PPP.
