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
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
