CHAPTER 8. TROUBLESHOOTING PROCEDURES FOR VOICE
TERMINALS
Simple Failures
If you have trouble with a voice terminal, follow your company’s established procedures for
reporting equipment troubles.
However, before reporting some problems, you may wish to
check the voice terminal for simple, obvious faults. For example, if the voice terminal
suddenly went dead, it may have been accidentally disconnected. Check the mounting cord
between the voice terminal and the information outlet (connecting block). Is it unplugged at
either end? Test it by disconnecting and reconnecting each end. Is the cord cut or
damaged? If so, ask your System Manager for a new one.
If you have an adjunct (such as a speakerphone or a display module) that quits working,
check the auxiliary power source. If the adjunct is a free-standing unit, make sure that the
cord between it and the voice terminal is not unplugged or cut.
Sometimes you activate a feature without meaning to or fail to cancel one when you should.
For example, if you return to your desk and forget to cancel Call Forwarding, you will not get
any calls. If you accidentally press your Send All Calls button, your calls will bypass you.
If you seldom use a particular procedure, consult the voice terminal operating instructions to
be sure of the steps. When a feature does not work properly, the problem may be in the
execution rather than in the equipment.
Do not spend too much time trying to diagnose problems, but do the light and ringing tests
to detect faulty lights and ringing.
