Transmit Section ON - Channel 1
This READ/WRITE bit-field is used to either turn on or turn off the
Transmit Driver associated with Channel 1. If the user turns on the
Transmit Driver, then Channel 1 will begin to transmit DS3, E3 or
STS-1 pulses on the line via the TTIP_1 and TRING_ 1 output pins.
Conversely, if the user turns off the Transmit Driver, then the TTIP_1
and TRING_1 output pins will be tri-stated.
0 - Shuts off the Transmit Driver associated with Channel 1 and tri-
states the TTIP_1 and TRING_ 1 output pins.
1 - Turns on or enables the Transmit Driver associated with Channel
1.
NOTE: If the user wishes to exercise software control over the state
of the Transmit Driver associated with Channel 1, then it is
imperative that the user pull the TxON_1 (pin 1) to a logic
"High" level.

Transmit Section ON - Channel 0
This READ/WRITE bit-field is used to either turn on or turn off the
Transmit Driver associated with Channel 0. If the user turns on the
Transmit Driver, then Channel 0 will begin to transmit DS3, E3 or
STS-1 pulses on the line via the TTIP_0 and TRING_ 0 output pins.
Conversely, if the user turns off the Transmit Driver, then the TTIP_0
and TRING_0 output pins will be tri-stated.
0 - Shuts off the Transmit Driver associated with Channel 0 and tri-
states the TTIP_0 and TRING_ 0 output pins.
1 - Turns on or enables the Transmit Driver associated with Channel
0.
NOTE: If the user wishes to exercise software control over the state
of the Transmit Driver associated with Channel 0, then it is
imperative that the user pull the TxON_0 (pin 38) to a logic
"High" level.
