Busying Out a Modem Card
To busy out a modem card in a Cisco access server, use the following commands beginning in global
configuration mode:
The modem busyout command disables the modem associated with a specified line from dialing and
answering calls. The modem busyout command can busy out and eventually terminate all 72 ports on
the Cisco AS5800 modem card.
Monitoring Resources on Cisco High-End Access Servers
The following tasks enable you to monitor the network access server (NAS) health conditions at the DS0
level, PRI bearer channel level, and modem level. Performing these tasks will benefit network operation
with improved visibility into the line status for the NAS for comprehensive health monitoring and
notification capability, and improved troubleshooting and diagnostics for large-scale dial networks.
Perform the following tasks to monitor resource availability on the Cisco high-end access servers:
• Enabling DS0 Busyout Traps—DS0 busyout traps are generated when there is a request to busy out
a DS0, when there is a request to take a DS0 out of busyout mode, or when busyout completes and
the DS0 is out-of-service. DS0 busyout traps are generated at the DS0 level for both CAS and ISDN
Command Purpose
Step 1
Router(config)# line shelf / slot / port
Specifies the line number, by specifying the shelf, slot, and port
numbers; you must type in the slashes. This command also
begins line configuration mode.
Step 2
Router(config-line)# modem busyout
Having specified the modem to be busied out with the line
command, enter the modem busyout command to busy out the
modem. The command disables the modem associated with line
shelf/slot/port from dialing and answering calls.You need not
specify a shelf/slot/port number again in this command.
Step 3
Router(config-line)# modem shutdown
Having specified the modem to be shut down with the line
command, enter the modem shutdown command to shut down
the modem, whether or not it has already been busied out. You
need not specify a shelf/slot/port number again in this command
because you have already done so with the line command.
Step 4
Router(config-line)# exit
Exits line configuration mode and returns to global
configuration mode.
Step 5
Router(config)# modem busyout-threshold
number
Specifies a threshold number using the modem
busyout-threshold number command to balance the number of
DS0s with the number of modem lines. For more information,
refer to the Cisco IOS Dial Technologies Command Reference.
Step 6
Router(config)# exit
Exits global configuration mode and returns to privileged EXEC
mode.
Step 7
Router# show busyout
From privileged EXEC mode, verifies that the line is busied out.
If there are active calls, the software waits until the call
terminates before the line is busied out.
