Transmit TTIP Output - Positive Polarity Signal - Channel 0:
Transmit TTIP Output - Positive Polarity Signal - Channel 1:
Transmit TTIP Output - Positive Polarity Signal - Channel 2:
These output pins along with the corresponding TRING_n output pins, function
as the Transmit DS3/E3/STS-1 Line output signal drivers for a given channel, of
the XRT75R03.
Connect this signal and the corresponding TRING_n output signal to a 1:1
transformer.
Whenever the Transmit Section of the Channel generates and transmits a posi-
tive-polarity pulse onto the line, this output pin will be pulsed to a "higher-volt-
age" than its corresponding TRING_n output pins.
Conversely, whenever the Transmit Section of the Channel generates and
transmit a negative-polarity pulse onto the line, this output pin will be pulsed to a
"lower-voltage" than its corresponding TRING_n output pin.

Transmit Ring Output - Negative Polarity Signal - Channel 2:
These output pins along with the corresponding TTIP_n output pins, function as
the Transmit DS3/E3/STS-1 Line output signal drivers for a given channel,
within the XRT75R03.
Connect this signal and the corresponding TTIP_n output signal to a 1:1 trans-
former.
