Ringing, Discriminating
Description
Allows the extension user to identify the incoming call by the ringing pattern. (See User
Manual, 5.4.1 What is This Tone?)
Conditions
• When there are multiple incoming calls and the extension goes from off-hook to on-hook,
the calls are rung according to the following priority:
a) Transfer Hold Recall
b)
An incoming call from a line in which the Prime Line Preference — Incoming function
has been set (with a digital proprietary telephone only)
c) Call Waiting
d)
Incoming calls; Hold Recall; Transfer Recall; Unattended Conference Recall
• If multiple incoming calls arrive at an on-hook extension simultaneously, priority as to
which calls should be rung is generally on a "first-come first-served" basis. In the case of
digital proprietary telephones (DPT), however, when the Prime Line Preference —
Incoming function has been set, this line takes precedence.
• Incoming TAFAS calls can be identified by ringing signals sent out from the external pager
or ringer. The ringing pattern is the same as the outside calls.
• The DPT user can select a desired tone frequency for each CO and the INTERCOM button.
