Revision 1.0
DISTINCTIVE RINGING-PRI
D-115 DISTINCTIVE RINGING-PRI
1. General Description
This feature provides distinctive station ringing patterns so that the station user can distinguish between internal
and external incoming calls.
2. Operating Procedure
No manual operation is required.
3. Programming
STEP 1: Assign the Basic Data for ISDN. (Refer to Chapter 3, “Basic Data Assignment for ISDN”.)
STEP 2: ASYD - System Data 1, Index 72, bit 6: Is DISTINCTIVE RINGING applied to calls handled via
the Attendant Console? 0/1: No/Yes. Otherwise these
calls will ring as station-to-station calls.
RINGER PATTERN 0
Normally used for C.O. Calls.
System Data 3, Index 0. Assign data 21H for C.O. calls to ring 1 second ON, 2 seconds OFF. Assign
42H for 2 seconds on, 4 seconds off, on a per-route basis. Go to ARTD CDN 12.
System Data 3, Index 3, bit 0. Should Ringer Pattern 0 be assigned interrupted ringing capability? 0/
1: No/Yes.
RINGER PATTERN 1
Normally used for Station-to-Station Calls.
System Data 3, Index 1. Assign data 42H for station-to-station calls to ring for 2 seconds ON and 4
seconds OFF.
System Data 3, Index 3, bit 1. Should ringer pattern 1 be assigned interrupted ringer pattern 1 ringing
capability? 0/1: No/Yes.
RINGER PATTERN 5
System Data 3, Index 3, bit 5. Enable ringer pattern 5? 0/1: No/Yes. This ringer pattern is applicable
to CALL BACK [C-1], OUTGOING TRUNK QUEUING [O-2], and CALL WAITING-
ORIGINATING [C-31].
System Data 3, Index 7. Assign data 24H for 4 seconds ON, 2 seconds OFF. (Ringer pattern 5.)
STEP 3: ARTD - To provide a distinctive ring to specific routes, assign data “1” to CDN 12, Distinctive Ring
(DR).
STEP 4: ASFC - Assign a Service Feature Class that allows SFI48, Burst Ringing, to PA-16LC port stations
that will not operate using DISTINCTIVE RINGING. With this feature, the system does
not look at ASYD, System Data 3, Index 3 bits 0 and 1 to determine how this telephone will
ring. Telex, FAX machines, and OPX stations may require a longer ringing signal. Digital
