Transmit STS-3/STM-1 Telecom Bus Interface - Payload Data Indica-
tor Output Signal:
This output pin indicates whether or not the Transmit STS-3/STM-1 Tele-
com Bus Interface is currently placing a Transport Overhead byte or a
non-Transport Overhead Byte (e.g., STS-1 SPE, STS-3c SPE, VC-3 or
VC-4 data) via the TXA_D[7:0] output pins.
This output pin is pulled "Low" for the duration that the Transmit STS-3/
STM-1 Telecom Bus Interface is transmitting a Transport Overhead byte
via the TXA_D[7:0] output pins.
Conversely, this output pin is pulled "High" for the duration that the
Transmit STS-3/STM-1 Telecom Bus Interface is transmitting something
other than a Transport Overhead byte via the TXA_D[7:0] output pins.

Transmit STS-3/STM-1 Telecom Bus Interface - Transmit Output
Data Bus pins:
These 8 output pins function as the Transmit STS-3/STM-1 Telecom Bus
Interface - Output data bus. If the STS-3/STM-1 Telecom Bus Interface
is enabled, then all outbound STS-3/STM-1 data is output via these pins
(in a byte-wide manner), upon the rising edge of the TXA_CLK output
pin.

Receive STS-3/STM-1 Telecom Bus Interface - Clock Input Signal:
This input clock signal functions as the clock source for the Receive
STS-3/STM-1 Telecom Bus Interface. All input signals are sampled
upon the falling edge of this input clock signal.
This clock signal should operate at 19.44MHz.Note:
NOTE: This input pin is only used if the STS-3/STM-1 Telecom Bus has
been enabled. It should be connected to GND otherwise.

This input pin should be pulled "Low" for the duration that the Receive

Conversely, this input pin should be pulled "High" for the duration that

NOTE: Connect this pin to GND if the STS-3/STM-1 Telecom Bus is NOT
enabled
