If the Transmit Line Build-Out Circuit is enabled, then
the Transmit Section of the Channel outputs shaped
pulses onto the line via the TTIP_(n) and TRing_(n)
output pins.
Enabling the Transmit Line Build-Out Cir-
Enable the Transmit Line Build-Out circuit for each
channel 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", as illustrated below.

If the Transmit Line Build-Out circuit is disabled, then
the XRT73LC04A outputs partially shaped pulses on-
to the line via the TTIP_(n) and TRing_(n) output
pins.
Disabling the Transmit Line Build-Out Cir-
Disable the Transmit Line Build-Out circuit by doing
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.
