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.
