51 MAXIMUM TONE OFF PERIOD FOR ANY TONE
This delay must be set at a value equal to the largest value for any of
the following delays in the Application Delay Table: 55, 65, 67, 71 or
75.
Use — When the system looks for ringback, busy, or fast busy tone, it
uses this delay to determine if the TONE OFF is a valid silence
period. If the TONE OFF is greater than this delay, the system
assumes an answer condition has occurred.
52 MINIMUM TONE OFF PERIOD FOR ANY TONE
This delay must be set at a value less than the value for any of the
following delays: 56, 66, 68, 72 or 76.
Use — When the system looks for ringback, busy, or fast busy tone, it
uses this delay to determine if the TONE OFF is a valid silence
period. If the TONE OFF is less than this delay, the system assumes
an answer condition has occurred.
53 RINGBACK MAXIMUM TONE ON PERIOD
This delay is the longest a TONE ON can be to qualify as ringback.
Use — The system uses this delay to determine if the tone cadences it
is monitoring is ringback. If the TONE ON is longer than this delay,
the system assumes it is not ringback.
54 RINGBACK MINIMUM TONE ON PERIOD
This delay is the shortest a TONE ON can be to qualify as ringback.
Use — The system uses this delay to determine if the tone cadences it
is monitoring is ringback. If the TONE ON is shorter than this delay,
the system assumes it is not ringback.
55 RINGBACK MAXIMUM TONE OFF PERIOD
This delay is the longest a TONE OFF can be to qualify as ringback.
Use — The system uses this delay to determine if the tone cadences it
is monitoring is ringback. If the TONE OFF is longer than this delay,
the system assumes it is not ringback.
