Intermessage Delay and Kissoff Timeout.
This register field defines two parameters. The Intermessage Delay defines the time the Si2400
waits prior to sending a subsequent message. The Kissoff Timeout defines the time the Si2400
waits for a Kissoff Tone prior to declaring that there is no kissoff tone detected.
00 = Intermessage Delay is measured relative to the end of Kissoff and it is a fixed delay
of 2.4 s. The Kissoff Timeout is measured relative to the end of Kissoff and it is a fixed
value of 2 s.
01 = Intermessage Delay is measured relative to the end of Kissoff and it is determined by
S1F[4:0] (IMT). The Kissoff Timeout is measured relative to the end of Kissoff and it is deter-
mined by S1F[7:5] (KOT).
10 = Intermessage Delay is measured relative to the end of the previous message and it is a
fixed delay of 3.4 s. The Kissoff Timeout is measured relative to the end of Kissoff and it is a
fixed value of 2 s.
11 = Intermessage Delay is measured relative to the end of the previous message and it is
determined by S1F[7:5] (KOT). The Kissoff Timeout is measured relative to the end of Kissoff
and it is determined by S1F[7:5] (KOT).

IT
Interdigit Timing.
The controlled timing between the pulse digits.
00 = The timing between the end of a digit to the start of the next digit is fixed at 660 ms.
01 = The timing between the end of a digit to the start of the next digit is defined by the S2D
register.
10 = The timing between the start of a digit to the start of the next digit is fixed at 800 ms.
11 = The timing between the start of a digit to the start of the next digit is defined by the S2D
register.
Note: S36 is reconfigured as Alarm 1, a bit-mapped register, in !7 mode only. In all other modes, S36 is SKDTL (Second
Kissoff Tone Detect Length).
