3.3.3.1

Configuring the Trunk Settings

The 'Trunk Settings' page allows you to configure the device's trunks. This includes
selecting the PSTN protocol and configuring related parameters.
Some parameters can be configured when the trunk is in service, while others require you
to take the trunk out of service (by clicking the Stop button). Once you have "stopped" a
trunk, all calls are dropped and no new calls can be made on that trunk.
You can also deactivate a trunk (by clicking the Deactivate button) for maintenance.
Deactivation temporarily disconnects (logically) the trunk from the PSTN network. Upon
trunk deactivation, the device generates an AIS alarm on that trunk to the far-end (as a
result, an RAI alarm signal may be received by the device). A subsequent trunk activation
(by clicking the Activate button), reconnects the trunk to the PSTN network and clears the
AIS alarm. Trunk deactivation is typically used for maintenance such as checking the
trunk's physical integrity.
