Enabling the Transmit Line Build-Out Cir-
If the Transmit Line Build-Out Circuit is enabled, the
Transmit Section of Channel (n) of the XRT73L02 out-
puts shaped pulses onto the line via the TTIP_(n) and
TRing_(n) output pins.
Enable the Transmit Line Build-Out circuit for each
channel in the XRT73L02 by doing the following:
a. Operating in the Hardware Mode
Set the TxLEV_(n) input pin to "Low"
b. Operating in the HOST Mode
Set the TxLEV_(n) bit-field to "0".

Disabling the Transmit Line Build-Out Cir-
If the Transmit Line Build-Out circuit is disabled, the
XRT73L02 outputs partially-shaped pulses onto the
line via the TTIP_(n) and TRing_(n) output pins.
To disable the Transmit Line Build-Out circuit, do the
following:
a. Operating in the Hardware Mode
Set the TxLEV_(n) input pin to "High".
b. Operating in the HOST Mode
Set the TxLEV_(n) bit-field to "1" as illustrated
below.
