Reviewing and Configuring Voice Interf aces
Voice ports connect the SmartSwitch 1800 to telephony equipment. Connections to
the frame relay network are mad e over Voi ce Interface s, which ar e assig ned to DLCIs
on physi c al fra m e rela y ports .
A Voice Interface record contains node numbers that identify the local SmartSwitch
1800 and the device at the remote end of the frame relay connection. When a call is
received, the dialing scheme in the SmartSwitch 1800 checks the node number
addressed in the call against a list maintained by the Voice software. If the number is
that of the remote node (called the "peer" node), the call is forwarded out the frame
relay port.
