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).
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]).
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.
Read returns 0.
Read returns zero.
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.
