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 monitoring mode allowing the DSP to receive line activity without
going off-hook. This mode is used for caller-ID detection.
When MODE bit = 1 (Register 18, bit 2), the device consumes ~7 µA from the phone line
when in on-hook line monitor mode. When MODE = 0, the device consumes ~450 µA from
the phone line when in on-hook line monitor mode.
Note: This bit should be cleared before setting the OH bit.
Ring Detect.
0 = Reset either 4.5–9 seconds after last positive ring is detected or when the system exe-
cutes an off-hook.
1 = Indicates a ring is occurring.
Off-Hook.
0 = Line-side device on-hook.
1 = Causes the line-side chip to go off-hook. This bit operates independently of the OHE bit
and is a logic OR with the off-hook pin when enabled. When the MODE bit (Register 12, bit 2)
is set to 1, the device will go on-hook without enabling the off-hook counter, thus allowing the
device to go immediately (i.e., no timeout required on the counter) back off-hook when the
MODE bit is cleared. This is useful in supporting Type II caller ID.
Note: The ONHM bit should be cleared before setting this bit.
