D-10 Distinctive Ringing
D-10 Distinctive Ringing
General Description
This feature provides distinctive station ringing patterns so that the user can distinguish between internal and
external incoming calls.
Operating Procedure
No manual operation is required.
Service Conditions
Ringing Patterns
1. Ringing for Incoming Internal Call
a.) When a Service Feature Class that allows Personal Ringer (ASFC command, SFI 148) is assigned
to a station:
RINGER PATTERN 1 - Ringing for Incoming Internal Call to Pilot Number:
2-second ring / 4-second silence
RINGER PATTERN 5 - Ringing for Incoming Internal Call to Personal Number (ex. My Line):
Note
2-second ring (3 bursts) / 1-second silence
Note:
Personal Number means the telephone number allowed Personal Ringer function.
b.) When a Service Feature Class that restricts Personal Ringer (ASFC command, SFI 148) is
assigned to a station:
RINGER PATTERN 1 - 2-second ring / 4-second silence
2. Ringing for Incoming External Call:
a.) RINGER PATTERN 0 - 1-second ring / 2-second silence
3. Recall Ringing for CALL BACK [C-1], CALL WAITING - ORIGINATING [C-31], or OUTGOING
TRUNK QUEUING [O-2]:
a.) RINGER PATTERN 1 - 2-second ring / 4-second silence
Or
RINGER PATTERN 5 - 2-second ring (3 bursts) / 1-second silence
Note: These timing parameters can be changed via the end users requirements (1-15 seconds).
4. This feature may be assigned per-trunk route via system data programming.
5. If an Off-Premises Station (OPX) or denied station is assigned to a station line, an option is available for
that Class of Service to eliminate burst ringing signals.
6. The DISTINCTIVE RINGING interruption rates can be optionally selected on a per-system basis. In this
case, system initialization may be required.
7. An option is available on a per-trunk group basis to provide one-burst ringing on terminating calls.
8. When calling a third station (THREE-WAY CALLING [T-2], CONSULTATION HOLD [C-17], etc.),
the ringing signal to the called station depends on the type of facility (station or trunk) on hold.
Interactions
1. CALL HOLD [C-6]: Recall ringing for CALL HOLD [C-6] can be distinguished between a held station
call (2-burst ringing) from a held trunk call (1-burst ringing).
