TxNEG5
I
Transmitter - Negative Data Input – Channel 5:
The exact signal that should be applied to this input pin depends upon
whether the user intends to operate the “Transmit Section” (of the Channel 5)
in “Clocked” or “Clockless” Mode.
Clocked Mode:
The Terminal Equipment should apply bit-wide NRZ pulses on this input pin,
whenever the Terminal Equipment needs to transmit a “negative-polarity”
pulse onto the line via TTIP5 and TRing5 output pins. The XRT5997
device will sample this input pin upon the falling edge of the TCLK5 signal.
Clockless Mode:
The Terminal Equipment should apply RZ pulses to this input pin, anytime
the Terminal Equipment needs to transmit a “negative-polarity” pulse onto the
line via TTIP5 and TRing5 output pins.

TxPOS5
I
Transmitter - Positive Data Input – Channel 5:
The exact signal that should be applied to this input pin depends upon
whether the user intends to operate the “Transmit Section” (of Channel 5) in
the “Clocked” or “Clockless” Mode.
Clocked Mode:
The Terminal Equipment should apply bit-wide NRZ pulses on this input pin,
whenever the Terminal Equipment needs to transmit a “positive-polarity”
pulse onto the line via TTIP5 and TRing5 output pins. The XRT5997
device will sample this input pin upon the falling edge of the TClk5 signal.
Clockless Mode:
The Terminal Equipment should apply RZ pulses to this input pin, anytime the
Terminal Equipment needs to transmit a “positive-polarity” pulse onto the line
via TTIP5 and TRing5 output pins.

RxNEG4
O
Receiver 4 Negative Data Out:
This output pin will pulse “high” whenever Channel 4, within the XRT5997
device has received a “Negative Polarity” pulse, in the incoming line signal,
at the RTIP4/RRing4 inputs.
47
RxPOS4
O
Receiver 4 Positive Data Out:
This output pin will pulse “high” whenever Channel 4, within the XRT5997
device has received a “Positive Polarity” pulse, in the incoming line signal, at
RTIP4/RRing4 inputs.
