Isolating and Correcting Troubles

To isolate and correct a trouble:
FIRST: Determine if more than one voice terminal or basic Touch-Tone or rotary
telephone is experiencing the trouble.
SECOND: If the trouble appears on only one voice terminal or telephone, find the
symptom in the list below titled "A. Trouble on One Telephone." The list includes
examples of problems categorized under each symptom. Turn to the tab divider for the
symptom and follow the procedures for your specific problem.
If the same problem appears on all or most telephones, find the
"B. Trouble on Several Telephones." Turn to the tab divider for
the procedures for your specific problem.
For any problem common to several voice terminals or telephones, check for bent or
broken pins on the control unit backplane. If any pins are damaged, contact your
equipment supplier. Never reinsert a module in a slot with bent pins.
Refer to the functional overview or CIBs in this manual if you need more detail on any
component. For more information on programming voice terminals, refer to the User's Guide:
Models 1030 and 3070 and Administration Manual: Models 1030 and 3070 that come with the
Feature Module.
The index will also help you find information on specific problems. If you cannot find your
problem in the symptom list or index, contact your equipment supplier.
