Ring Detect Signal Negative.
0 = No negative ring signal is occurring.
1 = A negative ring signal is occurring.
Ring Detect Signal Positive.
0 = No positive ring signal is occurring.
1 = A positive ring signal is occurring.
On-Hook Line Monitor.
0 = Normal on-hook mode.
1 = Enables low-power on-hook monitoring mode allowing the host to receive line activity
without going off-hook. This mode is used for caller-ID detection.
Ring Detect.
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.
Off-Hook.
0 = Line-side device on-hook.
1 = Causes the line-side device to go off-hook.
