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.
