RxNEG2
O
Receiver 2 Negative Data Out:
This output pin will pulse “high” whenever Channel 2, within the XRT5997
device has received a “Negative Polarity” pulse, in the incoming line signal,
at RTIP2/RRing2 inputs.
35
RxPOS2
O
Receiver 2 Positive Data Out:
This output pin will pulse “high” whenever Channel 2, within the XRT5997
device has received a “Positive Polarity” pulse, in the incoming line signal, at
RTIP2/RRing2 inputs.
36
LOS2
O
Receiver 2 Loss of Signal:
This output pin toggles “high” if Channel 2, within the XRT5997 device has
detected a “Loss of Signal” condition in the incoming line signal.

Receiver 5 Loss of Signal:
This output pin toggles “high” if Channel 5, within the XRT5997 device has
detected a “Loss of Signal” condition in the incoming line signal.
Note: 1Internally pull-up with 50K resistor

RxPOS5
O
Receiver 5 Positive Data Out:
This output pin will pulse “high” whenever Channel 5, within the XRT5997
device has received a “Positive Polarity” pulse, in the incoming line signal, at
RTIP5/RRing5 inputs.
42
RxNEG5
O
Receiver 5 Negative Data Out:
This output pin will pulse “high” whenever Channel 5, within the XRT5997
device has received a “Negative Polarity” pulse, in the incoming line signal,
at RTIP5/RRing5 inputs.
43
TxClk5
I
Transmitter Clock Input – Channel 5:
If the user operates Channel 5 (within the XRT5997 device) in the “clocked”
mode, then the “Transmit Section” of the Channel 5 will use the falling edge of
this signal to sample the data at the TxPOS5 and TxNEG5 input pins.
NOTE: If the user operates the Channel 5 in the “clockless” mode, then the
Terminal Equipment should not apply a clock signal to this input pin.
