Disabling Analog Ports

You can disable an analog port (FXS or FXO). When disabled, the port cannot be used and signaling is not transmitted through the port. The port's LED is lit red. By default, all analog ports are enabled.

To disable an analog port through CLI:
(config-voip)# interface fxs-fxo
(fxs-fxo)# analog-port-enable <module>/<port> [on|off]

For example, to disable Port 2 on Module 1:

(fxs-fxo)# analog-port-enable 1/2 off
