CVOICE v6.0—2-31

Summary  Voice ports on routers and access servers emulate physical telephony switch connections.  Analog voice port interfaces connect routers in packet-based networks to analog two-wire or four-wire circuits in telephony networks.  FXS, FXO, and E&M ports have several configuration parameters.

CVOICE v6.0—2-32

Summary (Cont.)  CAMA is used for 911 and E911 services.  DID service enables callers to dial an extension directly on a PBX or packet voice system.  You can set a number of timers and timing parameters for finetuning the voice port.  The show, debug, and test commands are used for monitoring and troubleshooting voice functions in the network.
