Description
Receive Positive Pulse Output:
This output pin will pulse “high” whenever the XRT59L91 device has
received a “Positive Polarity” pulse, in the incoming line signal, at
RTIP/RRing inputs.
7
RxNEG
O
Receive Negative Pulse Output:
This output pin will pulse “high” whenever the XRT59L91 device has
received a “Negative Polarity” pulse, in the incoming line signal, at
RTIP/RRing inputs.
8
RxLOS
O
Receive Loss of Signal Output Indicator:
This output pin toggles “high” if the XRT59L91 device has detected a
“Loss of Signal” condition in the incoming line signal.
