IST
Intrusion Settling Time.
0000 = IST equals 1 second.
Delay between when the ISOmodem goes off-hook and the off-hook intrusion algorithm
begins (250 ms units).
3LCLD
Loop Current Loss Detect.
0 = Disable.
1 = Enables the reporting of “I” and “L” result codes while off-hook. Will assert ALERT if
GPIO4 (SE2[7:6]) is enabled as ALERT. Will assert NLD (S14[2]).
2:1
IB
Intrusion Blocking.
This feature only works when SDF
≠ 0x00. Defines the method used to block the off-hook
intrusion algorithm from operating after dialing has begun.
00 = No intrusion blocking.
01 = Intrusion disabled from start of dial to end of dial.
10 = Intrusion disabled from start of dial to register S29 time out.
11 = Intrusion disabled from start of dial to carrier detect or to “N” or “n” result code.

Deglitch Sample Rate.
Sets the sample rate for the deglitch algorithm and the off-hook intrusion algorithm
(40 ms units).
0000000 = Disables the deglitch algorithm, and sets the off-hook intrusion sample
rate to 200 ms and delay between compared samples to 800 ms.
