Description

Receiver 1 Positive Data Out:

This output pin will pulse “high” whenever Channel 1, within the XRT5997

device has received a “Positive Polarity” pulse, in the incoming line signal,

at RTIP1/RRing1 inputs.

Receiver 1 Negative Data Out:

This output pin will pulse “high” whenever Channel 1, within the XRT5997

device has received a “Negative Polarity” pulse, in the incoming line signal,

at tRTIP1/RRing1 inputs.

Positive Supply - (+3.3V ± 5%). Digital Circuitry.

Receiver 7 Loss of Signal Output Indicator:

This output pin toggles “high” if Channel 7, within the XRT5997 device has

detected a “Loss of Signal” condition in the incoming line signal.

Receiver 7 Positive Data Out:

This output pin will pulse “high” whenever Channel 7, within the XRT5997

device has received a “Positive Polarity” pulse, in the incoming line signal,

at RTIP7/RRing7 inputs.

Receiver 7 Negative Data Out:

This output pin will pulse “high” whenever Channel 7, within the XRT5997

device has received a “Negative Polarity” pulse, in the incoming line signal,

at RTIP7/RRing7 inputs.

Receiver 1 Positive Bipolar Input:

The Receive Section of Channel 1 uses this input pin, along with RRing1

to receive the bipolar line signal from the “Remote E1 Terminal”.

Receiver 1 Negative Bipolar Input:

The Receive Section of Channel 1 uses this input pin, along with RTIP1 to

receive the bipolar line signal from the “Remote E1 Terminal”.

Positive Supply - (+3.3V ± 5%). Analog Circuitry.

Analog Ground

Positive Supply - (+3.3V ± 5%). Receiver 1, 2, 3, 5.

Receiver 2 Negative Bipolar Input:

The Receive Section of Channel 2 uses this input pin, along with RTIP2 to

receive the bipolar line signal from the “Remote E1 Terminal”.

Receiver 2 Positive Bipolar Input:

The Receive Section of Channel 2 uses this input pin, along with RRing2

to receive the bipolar line signal from the “Remote E1 Terminal”.
