point, this data is routed through the remainder of the Transmit Section of the XRT73LC00A and transmitted
out onto the line via the TTIP and TRING output pins.
Figure 31 illustrates the path that the data takes in the XRT73LC00A when the chip is configured to operate in
the Remote Loop-Back Mode.
During Remote Loop-Back operation, any data which is inputted via the RTIP and RRING input pins is also
outputted to the Terminal Equipment via the RPOS, RNEG and RCLK output pins.
The XRT73LC00A can be configured to operate in the Remote Loop-Back Mode by employing either one of
the following two steps
If the XRT73LC00A is operating in the HOST Mode:
Access the Microprocessor Serial Interface and write a “1” into the RLB bit-field and a “0” in the LLB bit-field in
Command Register CR4.
If the XRT73LC00A is operating in the Hardware Mode:
Set the RLB input pin (pin 15) to “High” and the LLB input pin (pin 16) to “Low”.

TXOFF Features
The XRT73LC00A allows the Transmit Driver in the Transmit Section of the chip to be shut off. This feature
can be advantageous for system redundancy conditions or during diagnostic testing. This feature can be
activated by either of the following ways.
When the XRT73LC00A is operating in the Hardware Mode
