42 Channel Maintenance
This chapter describes channel-related maintenance.
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.
If a voice call is currently in progress on the B-channel, it is disconnected when the
B-channel is restarted.
B-channel restart can only be done if the D-channel of the trunk to which it belongs
is synchronized (Layer 2).
B-channel restart does not affect the B-channel's configuration.
Locking and Unlocking Trunk Groups
You can lock a Trunk Group to take its trunks (and their channels) out of service. When you initiate
a lock, the device rejects all new incoming calls for the Trunk Group and immediately terminates
active calls (busy channels), eventually taking the entire Trunk Group out of service.
For digital interfaces: You can lock a Trunk Group “gracefully”, whereby the device rejects new
incoming calls, but terminates busy channels only after a user-defined graceful period if they are
still busy by the end of the period. When configured to 0, graceful lock is disabled.
For analog interfaces: For Tel-to-IP calls, the device plays a fast busy tone when the phone is off-
hooked on the Tel side. For IP-to-Tel calls, the device rejects the incoming INVITE message.
When you lock a Trunk Group, the method for taking channels out-of-service is determined by the
following parameters:
