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.

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.
N
OTE
:
TxOE is ideal for redundancy applications. See the Redundancy
Applications Section of this datasheet for more details. Internally
pulled "Low" with a 50K
resistor.

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.
N
OTE
:
TCLKinv is a global setting that applies to all 8 channels.
