These input pins are used to select the Transmit Line Build-Out circuit of Chan-
nel n.
Setting these pins to "High" disables the Line Build-Out circuit of Channel n. In
this mode, Channel n outputs partially-shaped pulses onto the line via the
TTIP_n and TRing_n output pins.
Setting these pins to "Low" enables the Line Build-Out circuit of Channel n. In
this mode, Channel n outputs shaped pulses onto the line via the TTIP_n and
TRing_n 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 these pins to "1" if the cable length between the Cross-Connect and the
transmit output of Channel is greater than 225 feet.
2. Set these pins to "0" if the cable length between the Cross-Connect and the
transmit output of Channel is less than 225 feet.
These pins are active only if the following two conditions are true:
a. The XRT75L04 is configured to operate in either the DS3 or SONET STS-1
Modes.
b. The XRT75L04 is configured to operate in the Hardware Mode.

:
1.
These pins are internally pulled down.
2.
If the XRT75L04 is configured in HOST mode, these pins should be
tied to GND.
