Note The Cisco AS5350XM and Cisco AS5400XM universal gateways each support only one type of WAN feature card at a time. See Chapter 7, “Troubleshooting,” for more information.

Each T1 or E1 feature card provides physical line termination for multiple DS-0 channels and uses onboard HDLC controllers to terminate digital (ISDN) calls. For network specifications, see Table 3-1and Table 3-2. You can use the bantam jack ports on the feature card to monitor a line.

Online Installation and Removal of the T1 or E1 Feature Card

To remove a feature card without dropping any calls or connections, you will need to take the feature card out of service by using the busyout command to disable the feature card. The busyout command is executed on a per–feature card basis and will disable the card after waiting for the active services to terminate.

If there are active calls on the feature card after you execute the busyout command, wait for the calls to drop. To view the status of the termination process, use the show busyout command.
