44 Channel Maintenance
This chapter describes channel-related maintenance.
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

For example, to disable Port 2 on Module 1:
(fxs-fxo)# analog-port-enable 1/2 off
Resetting an Analog Channel
You can reset an analog (FXO or FXS) channel by disconnecting the current call (if exists). This is
sometimes useful, for example, when the device (FXO) is connected to a PBX and communication
between the two cannot be disconnected (e.g., when using reverse polarity).
➢ To reset an analog channel through the Web interface:
1. Open the Monitor home page (Monitor menu > ).
2. Click the required FXS or FXO port icon; a shortcut menu appears.
3. From the shortcut menu, choose Reset Channel; a message appears informing you when the
channel has reset.
4. Click the required port icon.
5. Click the Reset Port button; a message appears informing you that the port has successfully
reset.
Restarting a B-Channel
You can restart a specific B-channel belonging to an ISDN or CAS trunk, using the SNMP MIB
variable, acTrunkISDNCommonRestartBChannel. This may be useful, for example, for
troubleshooting specific voice channels.
