Hardware Escape Pin.
0 = Disable.
1 = Enable.
Enable “+++” Escape.
0 = Disable.
1 = Enable.
Caller ID Mask.
0 = Change in CID will not affect INT.
1 = A low to high transition in CID activates INT.
Overcurrent Detect Mask.
0 = Change in OCD does not affect INT. (“X” result code is not generated in command
mode.)
1 = A low to high transition in OCD will activate INT. (“X” result code is generated in command
mode.)
Parallel Phone Detect Mask.
0 = Change in PPD does not affect INT.
1 = A low to high transition in PPD will activate INT.
Ring Indicator.
0 = Change in RI does not affect INT.
1 = A low to high transition in RI activates INT.
Data Carrier Detect Mask.
0 = Change in DCD does not affect INT.
1 = A high to low transition in DCD (U70, bit 0), which indicates loss of carrier, activates
INT.
Caller ID (sticky).
Caller ID preamble has been detected; data will soon follow. Clears on :I read.
Overcurrent Detect (sticky).
Overcurrent condition has occurred. Clears on :I read.
Parallel Phone Detect (sticky).
Parallel phone detected since last off-hook event. Clears on :I read.
Ring Indicator.
Active high bit when the Si2457/34/15/04 is on-hook, indicates ring event has occurred. Clears
on :I read.
Data Carrier Detect (status).
Active high bit indicates carrier detected (equivalent to inverse of DCD pin).
