D-90D Delayed Ringing - D
term
General Description (cont’d)
DELAYED RINGING may also be used for calls terminated to single-line telephone appearances on a D
term
. Calls
to single line appearances that are not answered within a preprogrammed time will ring on the next station in
sequence.
A call rings on Single Line Station A. If Station A does not answer within a preprogrammed time, the call also rings
on D
term
Station B. If the call is not answered within the second preprogrammed time, the call also rings on D
term
Station C.
Operating Procedure
No manual operation of the feature is required after it has been programmed in system data.
Service Conditions
1. This feature is available for multi-lines on D
term
s.
2. Delay timing for each line on the D
term
may be programmed through the MAT.
3. Delay timing may be 10, 20, or 30 seconds.
Interactions
1. Off-hook ringing on a D
term
will follow the assigned DELAYED RINGING-D
term
[D-90D] timer the
same as on-hook ringing.
2. Stations that have multi-line appearances with DELAYED RINGING-D
term
assigned must be aware of
the interaction with CALL FORWARDING-DON’T ANSWER [C-2]. Example: Station A appears on
D
term
B with a delayed ringing of 30 seconds (RG = 4); and also on D
term
C with a delayed ringing time
of 20 seconds (RG = 5). If Station A sets CALL FORWARDING-DON’T ANSWER [C-2] and the CALL
FORWARDING-DON’T ANSWER [C-2] timer is set at 24 seconds, when an incoming call comes into
Station A, it will begin to ring; at 20 seconds D
term
C will begin to ring also; at 24 seconds the call will
forward to Station A’s target destination and Station A and D
term
C will stop ringing. D
term
B never rings.
3. After a call has been answered by a secretary, the activation of the boss/secretary feature by the secretary
to a single-line boss station will not reactivate the DELAYED RINGING-D
term
cycle.
