Telephone Problems
Once you isolate a problem to the telephone (or a group of telephones), you can
run various tests to check a telephone’s operation.
Use the procedure below as a general guideline for troubleshooting telephones.
!Replace the telephone (or adjunct) with one that works properly.
!If the problem persists, connect the telephone directly to the
control unit, using a cord that works properly.
■ If this solves the problem, replace the original cord.
■ The power supply may be shorted or open. If the wiring has been
crushed or severed, replace it.
a. Test the power supply for 48 VDC with a voltmeter or by
reconnecting the telephone or adjunct.
b. If the test for 48 VDC fails, replace the circuit pack in the
telephone or adjunct.
!
CAUTION:
A faulty circuit pack has the potential to damage the power supply,
which can cause widespread damage throughout the system.
!If the problem persists, replace the mounting cord.
!If the problem continues, proceed as described in the next sections.
