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:

1Dial *03 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 *03 a single-line telephone works only if telephone has a touch- tone dialpad and the trunk accepts touch-tone dialing.

2Repeat Step 1 for all outgoing trunks.

3Dial an incoming trunk on the system.

4Have someone answer the call at another telephone; verify that you have good two-way communication.

5Repeat Steps 3 and 4 for all incoming trunks.

6Hang up to exit test mode.

Testing DID Trunks

To test DID trunks, follow the steps below:

1Have someone at the central office check all DID trunks, or have someone call from the outside to check each DID trunk.

2When the first trunk rings, answer it.

3Instruct the caller to put the call on hold or put down the handset while making the next call.

4When the next trunk rings, put the previous call on hold and repeat this procedure until all eight DID trunks have been connected successfully.

5When all trunks are connected with good communication, disconnect each call and have the caller do the same.
