Receive Overhead Data Output Interface - output
This output pin functions as the Receive Overhead Data output for the
receive system side interface when the XRT94L31 is configured to oper-
ate in DS3/E3 mode, however, it functions as the Receive STS-1 Over-
head Data output when the device is configured to operate in the STS-1
mode.
When configured to operate in DS3/E3 mode:
All overhead bits, which are received via the Receive Section of the
channel, will be output via this output pin, upon the rising edge of
RxOHClk_n.
When configured to operate in STS-1 mode:
These output pins, along with RxOHEnable_n, RxOHClk_n and
RxOHFrame_n function as the Receive STS-1 TOH and POH Output
Port.Each bit, within the TOH and POH bytes (within the incoming STS-1
data stream) is updated upon the falling edge of RxOHClk_n. As a con-
sequence, external circuitry receiving this data, should sample this data
upon the rising edge of RxOHClk_n.

1.
The external circuitry can determine whether or not it is
receiving POH or TOH data via this output pin. The
RxOHEnable_n output pin will be "High" anytime POH data is
being output via these output pins. Conversely, the
RxOHEnable_n output pin will be "Low" anytime TOH data is
being output via these output pins.
2.
TOH and POH data, associated with Receive STS-1 TOH and
POH Processor Block - Channel 0 will be output via the
RxOH_0, and so on.

Receive Overhead Data Output Interface - Enable Output
This output pin functions as the Receive Overhead Enable output for the
receive system side interface when the XRT94L31 is configured to oper-
ate in DS3/E3 mode, however, it functions as the Receive STS-1 Over-
head Data output when the device is configured to operate in the STS-1
mode.
When configured to operate in DS3/E3 mode:
The channel will assert this output signal for one RxOHClk_n period
when it is safe for the local terminal equipment to sample the data on the
RxOH_n output pin.
When configured to operate in STS-1 mode:
These output pins, along with RxOHClk_n, RxOHFrame_n and RxOH_n
function as the Receive STS-1 TOH and POH Output Port.
These output pins indicate whether POH or TOH data is being output via
the RxOH_n output pins.
These output pins will toggle "High" coincident with when POH data is
being output via the RxOH_n output pins. Conversely, these output pins
will toggle "Low" coincident with when TOH data is being output via the
RxOH_n output pins.
These output pins are updated upon the falling edge of RxOHClk_n. As
a consequence, external circuitry, receiving this data, should sample this
data upon the rising edge of RxOHClk_n.
