On-Hook Line Monitor.
0 = Normal on-hook mode.

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

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.
