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 dial-only feature cards support all modem standards and features. In contrast to the more traditional
line-to-modem mapping, lines are mapped to a system processing engine (SPE) that resides on the universal port and dial-only
feature card. Associated SPE firmware serves a function similar to that of modem code on a modem ISDN channel aggregation
(MICA) technologies 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 and dial-only feature card 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
