You may have an older version of the
System 85 software so some features may
work differently from the procedures described
in this guide.
See your system manager for a list of feature
access codes for features assigned to your voice
terminal. Then, write the codes in this guide.

steadily, the voice terminal is not
communicating with the PBX.
4 Find a working voice terminal of the same type
as your own. Unplug this voice terminal from
its wall jack. Plug your voice terminal into
that jack and check if it gets dial tone.
5 If your voice terminal still does not work, plug
the working voice terminal (of the same type)
into your modular wall jack. If the working
voice terminal has dial tone, your own voice
terminal is faulty. See your system manager.
