Receive STS-3/STM-1 Telecom Bus Interface - Receive Input Data
Bus pins:
These 8 input pins function as the Receive STS-3/STM-1 Telecom Bus
Interface Receive Input data bus. All STS-3/STM-1 data is sampled and
latched (into the XRT94L31, via these input pins) upon the falling edge
of the RXA_CLK input pin.
NOTE: These input pins are only active if the Receive STS-3/STM-1
Telecom Bus Interface has been enabled. If the XRT94L31 is
configured to exchange STS-3/STM-1 data via the PECL
Interface (instead), tie these pins to GND.

Transmit TOH Input Port - Clock Output:
This output pin, along with the TxTOHEnable, TxTOHFrame output pins
and the TxTOH and TxTOHIns input pins function as the Transmit TOH
Input Port.The Transmit TOH Input Port is usedr to insert the users own
value for the TOH bytes (in the outbound STS-3/STM-1 signal).
This output pin provides the user with a clock signal. If the TxTOHEn-
able output pin is "High" and if the TxTOHIns input pin is pulled "High",
then the user is expected to provide a given bit (within the TOH) to the
TxTOH input pin, upon the falling edge of this clock signal. The data,
residing on the TxTOH input pin will be latched into the XRT94L31 upon
the rising edge of this clock signal. The XRT94L31 will then insert this
particular TOH bit value into the appropriate TOH bit positions within the
outbound STS-3 data-stream.
NOTE: The Transmit TOH Input Port only supports the insertion of the
TOH within the first STS-1, within the outbound STS-3 signal.

Transmit TOH Input Port - TOH Enable (or READY) indicator:
This output pin, along with the TxTOHClk, TxTOHFrame output pins and
the TxTOH and TxTOHIns input pins function as the Transmit TOH Input
Port.
This output pin will toggle and remain "High" anytime the Transmit TOH
Input Port is ready to externally accept TOH data.
To externally insert user values of TOH into the outbound STS-3 data
stream via the Transmit TOH Input Port, do the following.
Continuously sample the state of TxTOHFrame and this output pin
upon the rising edge of TxTOHClk.
Whenever this output pin pulses "High", then the user's external
circuitry should drive the TxTOHIns input pin "High".
Next, output the next TOH bit, onto the TxTOH input pin, upon the
rising edge of TxTOHClk
