Transmit Ring Output
The XRT75VL00 uses this pin along with TTIP to transmit a bipolar signal to the
line using a 1:1 transformer.

Transmit Line Build-Out Enable/Disable Select
This input pin is used to enable or disable the Transmit Line Build-Out circuit.
Setting this pin to "High" disables the Line Build-Out circuit. In this mode, par-
tially-shaped pulses are output onto the line via the TTIP and TRING output
pins.
Setting this pin to "Low" enables the Line Build-Out circuit. In this mode, shaped
pulses are output onto the line via the TTIPand TRING output pins.
To comply with the Isolated DSX-3/STSX-1 Pulse Template Requirements per
Bellcore GR-499-CORE or Bellcore GR-253-CORE:
1. Set this pin to "1" if the cable length between the Cross-Connect and the
transmit output is greater than 225 feet.
2. Set this pin to "0" if the cable length between the Cross-Connect and the
transmit output is less than 225 feet.
This pin is active only if the following two conditions are true:
a. The XRT75VL00 is configured to operate in either the DS3 or SONET STS-1
Modes.
b. The XRT75VL00 is configured to operate in the Hardware Mode.

This pin is internally pulled down.
If the XRT75VL00 is configured in HOST mode, this pin may be tied to
GND.
