Testing the System
Testing Ground-Start and Loop-Start Trunks
(Hybrid/PBX Systems Only)
To test the GS and LS outgoing and incoming trunks at a telephone, follow the
steps below:
1 Dial followed by the trunk ID number (01 through 80).
You should hear dial tone for a working trunk, a reorder tone for a DID trunk or
an invalid trunk number, or a busy tone if the trunk is in use.
NOTE:
Dialing on a single-line telephone works only if telephone has a touch-
tone dialpad and the trunk accepts touch-tone dialing.
2 Repeat Step 1 for all outgoing trunks.
3 Dial an incoming trunk on the system.
4 Have someone answer the call at another telephone; verify that you have
good two-way communication.
5 Repeat Steps 3 and 4 for all incoming trunks.
6 Hang up to exit test mode.
Testing DID Trunks
To test DID trunks, follow the steps below:
1 Have someone at the central office check all DID trunks, or have
someone call from the outside to check each DID trunk.
2 When the first trunk rings, answer it.
3 Instruct the caller to put the call on hold or put down the handset while
making the next call.
4 When the next trunk rings, put the previous call on hold and repeat this
procedure until all eight DID trunks have been connected successfully.
5 When all trunks are connected with good communication, disconnect
each call and have the caller do the same.
