The following example gracefully disables the modem associated with line 1 from dialing and answering
calls. The modem is disabled only after all active calls on the modem are dropped.
Router# configure terminal
Router(config)# line 1
Router(config)# modem busyout
The following example abruptly shuts down the modem associated with line 2. All active calls on the
modem are dropped immediately.
Router# configure terminal
Router(config)# line 2
Router(config)# modem shutdown
In the following example, the modem using TTY line 3 is actively supporting a call (as indicated by the
asterisk). However, we want to mark the modem bad because it has poor connection performance. First,
abruptly shut down the modem and drop the call with the modem shutdown command, and then enter
the modem bad command to take the modem out of service.
