Incoming Trunk Problems
If incoming trunks do not work properly, follow these steps:
1. Place an incoming call through the troubled trunk.
For a loop-start (LS) trunk, connect a single-line telephone to the trunk at the network
I
interface.
For a ground-start (GS) trunk, connect a single-line telephone to the trunk at the network
I
interface and press the GS button. (For GS trunks, the telephone must have a GS button
attached to it.)
2. Listen for ringing.
3. Pick up the handset and check line seizure.
4. Dial an outside number and verify that you have good two-way transmission.
5. At the maintenance console, check the trunk programming to be sure this trunk has been
properly translated. Refer to a copy of the completed System Planning Forms.
6. If the module continues to malfunction, replace it.
Outgoing Trunk Problems
If the system cannot seize outgoing trunks, follow these steps for analog lines:
You cannot perform this procedure on a rotary telephone.
1. Check for outside dial tone at the network interface.
For GS trunks, apply ground to the ring lead to get dial tone. If dial tone is not present, notify
the customer.
Steps 2 through 4 only apply to Hybrid/PBX mode. Go to Step 5 for systems in Key or
Behind Switch mode.
2. Pick up the handset of a test telephone to check for system dial tone;
Dial *03, then dial the maintenance password.
If the password is not known, check the System Information Report or ask to speak with
I
the system manager.
You can change the password without knowing the old password only when you perform
I
on-site maintenance through the ADMIN jack.
3. Dial the 2-digit trunk number (01—80) of the trunk you want to test.
4. Listen for dial tone.
If dial tone is not present, use a test telephone to isolate the problems either to the module
I
where the trunk terminates or to the location in the trunk access equipment.
