Trunk Errors
If the module continues to malfunction, replace it.
Incoming Trunk Problems
If incoming trunks do not work properly, try the following procedure.
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 interface.
For a ground-start (GS) trunk, connect a single-line telephone to
the trunk at the network interface and press the GS button. (For
GS trunks, the telephone must have a GS button attached to it.)
Listen for ringing.
Pick up the handset and check line seizure.
Dial an outside number and verify that you have good two-way
transmission.
At the maintenance terminal, check the trunk programming to be
sure this trunk has been properly translated.
See the system planning forms.
If the module continues to malfunction, replace it.
— If you are using a single-line telephone to dial out to an
E&M tie trunk or a T1 tie trunk, wait for a click before
dialing the outside number.
If the trunk is busy, you hear a busy tone. If you dial a
wrong trunk type (such as DID) or an invalid trunk number,
you hear a reorder tone.
