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.
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.
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.
Receive TIP Input:
This input pin, along with RRing is used to receive the bipolar line
signal from the “Remote E1 Terminal”.
Receive Ring Input:
This input pin, along with RTIP is used to receive the bipolar line
signal from the “Remote E1 Terminal”.
Receiver Ground Pin
Receiver Power Supply Pin: 3.3V + 5%
Transmit TIP Output:
The XRT59L91 device will use this pin, along with TRing, to transmit
a bipolar line signal, via a 1:2 step-up transformer.
Transmitter Power Supply Pin: 3.3V + 5%
Transmit Ring Output:
The XRT59L91 device will use this pin, along with TTIP, to transmit a
bipolar line signal, via a 1:2 step-up transformer.
