Function
Intrusion Settling Time (250 ms units).
15:12
IST[3:0]
Delay between when the modem goes off-hook and the off-hook intrusion algorithm begins.
Default is 1 s.
Hang-Up On Intrusion.
0 = Modem will not automatically hang up when and off-hook PPD interrupt occurs.
11
HOI
1 = Modem automatically hangs up on a PPD interrupt. If %Vn command are set, HOI also causes
the "LINE IN USE" result code upon PPD interrupt.
10
Reserved
Read returns zero.
Auto Overcurrent.
0 = Disable
1 = Enable
Note: AOC may falsely detect an overcurent condition in the presence of line reversals or other
transients.
9
AOC
Therefore, it should not be used where line reversals are common or may be expected.
Off-Hook Time (1 ms units).
8:0
OHT[8:0]
Time before LVCS is checked for overcurrent condition after going off-hook (30 ms default).
