Intrusion Settling Time (250 ms units).
Delay between when the ISOmodem goes off-hook and the off-hook intrusion algorithm
begins. Default is 1 s.
Hang-Up On Intrusion.
0 = ISOmodem will not automatically hang up when an off-hook PPD interrupt occurs.
1 = ISOmodem automatically hangs up on a PPD interrupt. If %Vn commands are set, HOI
also causes the “LINE IN USE” result code upon PPD interrupt.
Auto Overcurrent.
0 = Disable.
1 = Enable.
Note: AOC may falsely detect an overcurrent condition in the presence of line reversals or other
Off-Hook Time (1 ms units).
Time before LVCS is checked for overcurrent condition after going off-hook (30 ms default).
D13
transients. Therefore, this feature should not be used in applications or locations (such as
Japan) where line reversals are common or may be expected.
