Unused Trunks - Avaya 4600 Series Installation Manual

U nused Trunks
8 0 B
Summary
Each IP Office trunk card provides a fixed number of trunk ports. For digital trunks each trunk provides a
set number of digital channels. In cases where the number of trunks connected to the IP Office is lower
or the number of channels provided is lower, those unused trunks and channel must be disabled.
Failure to do this will cause problems with outgoing calls. For example, on a system with an ATM4
trunk card fitted but only two analog trunks actually connected, failure to disable the other two trunks
within the IP Office configuration will cause 50% of outgoing call attempts to fail.
Objective
Remove unused trunks and channels from the IP Office configuration.
Procedure
1. Within the IP Office configuration, select
2. For each line, set those lines or channels that are not connected or being used as out of service.
The location of the relevant setting varies for each trunk type.
