Description
Busy cadence minimum total time in seconds multiplied by 7200.
Country-specific settings for busy, ringback, and dialtone cadences
are specified by a range for ON time (minimum ON and maximum
ON) and a range for OFF time (minimum OFF and maximum OFF).
The Si2456/33/14 uses three registers to fully specify this range:
MTT, DLT, and MOT. MTT is the minimum total time and is equal to
the minimum ON time plus the minimum OFF time. DLT is the allow-
able delta. This is equal to maximum total time (maximum ON time
plus the maximum OFF time) minus the minimum total time (MTT).
MOT is simply the minimum ON time.
Example: A country specifies a busy tone with ON time from 1–2
seconds and OFF time from 3–4 seconds. Thus, minimum ON time
= 1 sec, maximum ON time = 2 sec, minimum OFF time = 3 sec,
and maximum OFF time = 4 sec. BMTT = 1 + 3 = 4 seconds, maxi-
mum total time = 2 + 4 = 6 seconds, so BDLT = 6 – 4 = 2 seconds,
and BMOT = 1.
Busy cadence delta in seconds multiplied by 7200.
Busy cadence minimum on time in seconds multiplied by 7200.
Ringback cadence minimum total time in seconds multiplied by
7200.
Ringback cadence delta in seconds multiplied by 7200.
