Testing the Ground-Start and Loop-Start Trunks

(Hybrid/PBX Systems Only)

Follow these steps to test the GS and LS outgoing and incoming trunks at a telephone:

1.Dial ✱ 03 followed by the trunk ID number-(01 — 80).

You should hear a 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 on a single-line telephone works only if telephone has a touch-tone dialpad and the trunk accepts touch-tone dialing.

2. Repeat 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 the test mode.
