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:

:
This input pin is only used if the STS-3/STM-1 Telecom Bus has
been enabled. It should be connected to GND otherwise.
