Octel 200/300 S.4.1 PB60019−01
FAST BUSY MAXIMUM TONE ON PERIOD
The longest delay that a TONE ON can be to qualify as a fast-busy tone.
Use — The message server uses this delay to determine whether the tone cadences that it is
monitoring is a fast-busy tone. If the TONE ON is longer than this delay, the message server
assumes that it is not a fast-busy tone.
FAST BUSY MINIMUM TONE ON PERIOD
The shortest delay that a TONE ON can be to qualify as a fast-busy tone.
Use — The message server uses this delay to determine whether the tone cadences that it is
monitoring is a fast-busy tone. If the TONE ON is shorter than this delay, the message server
assumes that it is not a fast-busy tone.
FAST BUSY MAXIMUM TONE OFF PERIOD
The longest delay that a TONE OFF can be to qualify as a fast-busy tone.
Use — The message server uses this delay to determine whether the tone cadences that it is
monitoring is a fast-busy tone. If the TONE OFF is longer than this delay, the message server
assumes that it is not a fast-busy tone.

Coordinate the following application-delay indexes for cadence recognition. Refer to Table 6-3.
- Set index 49 to a value equal to the largest value for any of the following delay indexes: 53, 61, 63,
69, or 71.
- Set index 50 to a value less than the value for any of the following delay indexes: 54, 62, 64, 70, or 74.
- Set index 51 to a value equal to the largest value for any of the following delay indexes: 55, 65, 67,
71, or 75.
- Set index 52 to a value less than the value for any of the following delay indexes: 56, 66, 68, 72, or 76.
