Receive Section ON - Channel n
This READ/WRITE bit-field is used to turn on or turn off the Receiver associated with
Channel n on a per channel basis. If the user turns on the Receiver, then Channel n
will Receive DS3, E3 or STS-1 pulses on the line via the RTIP_n and RRING_ n input
pins.
Conversely, if the user turns off the Receiver Driver (for channel n), the RTIP_n and
RRING_n input pins will be in a high impedance state.
0 - Shuts off the Receive Driver associated with Channel n and puts the RTIP_n and
RRING_ n input pins in a high impedance state.
1 - Turns on the Receive Driver associated with Channel n.

Transmit Section ON - Channel n
This READ/WRITE bit-field is used to turn on or turn off the Transmit Driver associated
with Channel n. If the user turns on the Transmit Driver, then Channel n will transmit
DS3, E3 or STS-1 pulses on the line via the TTIP_n and TRING_ n output pins.
Conversely, if the user turns off the Transmit Driver, then the TTIP_n and TRING_n
output pins will be tri-stated.
0 - Shuts off the Transmit Driver associated with Channel n and tri-states the TTIP_n
and TRING_ n output pins.
1 - Turns on the Transmit Driver associated with Channel n.
NOTE: The master TxON control pin(pin # P4) must be in a high state (logic 1) for this
operation to turn on any channel.
