Intrusion Settling Time.
0000 = IST equals 1 second.
Delay between when the ISOmodem
algorithm begins (250 ms units).
Loop Current Loss Detect.
0 = Disable.
1 = Enables the reporting of “I” and “L” result codes while off-hook. Asserts INT if
GPIO4 (SE2[7:6]) is enabled as INT.
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 zero.
