11.2 RING CADENCE CONFIGURATION
Using the above notation, the BNF description for the ring cadence patterns is as follows:
Timeval ::= time in milliseconds Repeatval ::= # of cycles to repeat
Tonename ::= "RING_0" "RING_1" "RING_2" "RING_3" "RING_4" "RING_5" "RING_6" "RING_7" "RING_8" "RING_9"
Idle ::= "IDLE"
Active ::= "ON" "OFF"
Inactive ::= Idle "(" Timeval ")"
Active ::= Active "(" Timeval ")" Sequence ::= Active Active "," Sequence Repetition ::= "[" Sequence "]" Repeatval Repeat ::= "R"
Cycle ::= Sequence Repetition
Fullsequence ::= Cycle Cycle "," Fullsequence Cadence ::= Fullsequence Fullsequence "," Repeat
Fullsequence"," Inactive "," Repeat Ring ::= Cadence
EXAMPLE RING CADENCE CONFIGURATION
200ms | 100ms | 200ms | 200ms | 100ms | 200ms | ||
| 300ms | 400ms |
| 4000ms | 300ms | 400ms | 4000ms |
1 cycle
For the ring cadence pattern above, the configuration would be:
RING_0 ON(200),OFF(300),ON(100),OFF(400),ON(200),OFF(4000),R
The Bellcore standard ring cadence patterns are:
NAME VALUE
RING_0 ON(2000),IDLE(4000),R
RING_1 ON(800),OFF(400),ON(800),IDLE(4000),R
