Testing Trunks Automatically; Maintenance-Busy Status - Avaya MERLIN MAGIX Maintenance And Troubleshooting Manual

Maintenance and Troubleshooting
If dial tone is present, dial a working outside number to verify that the call can be
I
completed.
– Dialing an outside number on a single-line telephone works only if the trunk accepts
touch-tone dialing.
– If you are using a single-line telephone to dial out to an E&M tie trunk or a T1 tie trunk,
wait for a click before dialing the outside number.
If the trunk is busy, you hear a busy tone. If you dial a wrong trunk type (such as DID)
or an invalid trunk number, you hear a reorder tone.
5. If the module continues to malfunction, replace it.

Testing Trunks Automatically

The automatic maintenance program takes the ports out of service when a trunk is malfunctioning.
When a port is out of service, it is has a maintenance-busy status. The trunk is periodically tested
and put back into service if possible.

Maintenance-Busy Status

When maintenance-busy is enabled and a trunk cannot be seized for an outgoing call, the trunk is
automatically put into a maintenance-busy state. When a trunk is in a maintenance-busy state, no
outgoing calls can be placed on it. However, the trunk can still receive incoming calls.
Maintenance-busy does not apply to DID trunks, since DID trunks cannot be used to
make outgoing calls.
While the trunk is in a maintenance-busy state, the software periodically runs tests, attempting to
seize the trunk:
If the seizure is unsuccessful, the trunk stays in a maintenance-busy state.

If the seizure is successful, the trunk is placed back in service.

If a test is running when an incoming call is received on the trunk, the test is dropped and the
I
call is processed.
No more than 50 percent of trunks in a pool can be in maintenance-busy states at one time. The
only exceptions are as follows:
User-imposed maintenance-busy (for example, module replacement)
I
Module maintenance-busy (for example, a loss-of-service alarm in the 100D module)

No external release at the central office end of the line
