1 = A positive ring signal is occurring.

Reserved Read returns zero.

ONHM

On-Hook Line Monitor.

0 = Normal on-hook mode.

without going off-hook. This mode is used for caller-ID detection.

RDT

0 = Reset 5 seconds after last positive ring is detected or when the system executes an

off-hook. Only a positive ring sets this bit when RFWE = 0. When RFWE = 1, either a positive

or negative ring sets this bit.

1 = Indicates a ring is occurring.

Reserved Read returns zero.

0OH
