Verify
To verify your D channel configuration:
•Enter the show interface serial command and make sure that the line protocol is up and that you are using the correct IP
interface. Also, make sure that excessive errors are not being reported.

Configuring the Universal Port Dial Feature Card and Lines
Rather than the more traditional line/modem one-to-one correspondence, lines are mapped to a service process element (SPE)
that resides on the universal port DFC. Associated SPE firmware serves a function similar to modem code on a MICA modem.
One SPE provides services for six ports, with additional ports per SPE. Busyout and shutdown can be configured at the SPE or
port level.
The universal port DFC performs the following functions:
•Converts pulse code modulation (PCM) bitstreams to digital packet data.
•Forwards converted and packetized data to the main processor, which examines the data and forwards it to the backhaul
egress interface.
•Supports all modem standards (such as V.34 and V.42bis) and features, including dial-in and dial-out.
Note For detailed information about the universal port DFC CLI commands, refer to Monitoring Voice and Fax Services on
the Cisco AS5350 and Cisco AS5400 Universal Gateway, available online at the following URL:
