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.
N
OTE
:
The master TxON control pin(pin # P4)
must
be in a high
state (logic 1) for this operation to turn on any channel.
