Description
Allows the extension user to identify the incoming call by the
ringing pattern. (See Section 5.1 “Tone / Ring 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:
<1> Consultation Hold Recall
<2> An incoming call from a line in which the Prime Line
Preference – Incoming function has been set (with a
proprietary telephone only)
<3> Call Waiting
<4> 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-serve” basis. In the case of proprietary telephones
(PT), however, when the Prime Line Preference – Incoming function
has been set, this line takes precedence.
• Incoming TAFAS (Trunk (Outside Line) Answer From Any Station)
calls can be identified by ringing signals sent out from the external
pager. The ringing pattern is the same as the outside calls.
• The digital PT user can select a desired tone frequency for each CO
button.
