Receive Differential Tip Input
RTIP is the positive differential input from the line interface. Along with the
RRING signal, these pins should be coupled to a 1:1 transformer for proper
operation.
Receive Differential Ring Input
RRING is the negative differential input from the line interface. Along with the
RTIP signal, these pins should be coupled to a 1:1 transformer for proper oper-
ation.
Transmit Output Enable
Upon power up, the transmitters are tri-stated. Enabling the transmitters is
selected through the serial microprocessor interface by programming the
appropriate channel register if this pin is pulled "High". If the TxOE pin is
pulled "Low", all 8 transmitters are tri-stated.

Driver Monitor Output
When no transmit output pulse is detected for more than 128 TCLK cycles, the
DMO pin will go "High" for a minimum of one TCLK cycle. DMO will remain
"High" until the transmitter sends a valid pulse.
Transmit Clock Input
TCLK is the input facility clock used to sample the incoming TPOS/TNEG data.
TPOS/TNEG data can be sampled on either edge of TCLK selected by TCLK-
inv in the appropriate global register.
