Tip To save the gateway configuration, save it to NVRAM. See the “Saving Configuration Changes” section on page 60.
Verifying D Channel Configuration
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 or Dial-Only Feature Cards
The universal port or
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 and
•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
