To test the GS and LS outgoing and incoming trunks at a telephone, follow the
steps below:
Dial
*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.
Repeat Step 1 for all outgoing trunks.
Dial an incoming trunk on the system.
Have someone answer the call at another telephone; verify that you have
good two-way communication.
Repeat Steps 3 and 4 for all incoming trunks.
Hang up to exit test mode.

To test DID trunks, follow the steps below:
Have someone at the central office check all DID trunks, or have
someone call from the outside to check each DID trunk.
When the first trunk rings, answer it.
Instruct the caller to put the call on hold or put down the handset while
making the next call.
When the next trunk rings, put the previous call on hold and repeat this
procedure until all eight DID trunks have been connected successfully.
When all trunks are connected with good communication, disconnect
each call and have the caller do the same.
