Off-Hook Sample Rate (40 ms units)
Sets the sample rate for the off-hook intrusion algorithms (1 second default).
Force ACL.
0 = While off-hook, ACL is automatically updated with LVCS.
1 = While off-hook, ACL does not change from the value written to it while on-hook.
Differential Current Level (3 mA units).
Sets the differential level between ACL and LVCS that will trigger an off-hook PPD interrupt
(default = 2).
Absolute Current Level (3 mA units, see Figure 7 on page 37).
ACL represents the value of LVCS current when the ISOmodem is off-hook and all parallel
phones are on-hook. If ACL = 0, then it is ignored by the off-hook intrusion algorithm.The
ISOmodem will also write ACL with the contents of LVCS before an intrusion and before
going on-hook (default = 0).
