Receive STS-1 TOH and POH Output Port - POH Data Indicator:
These output pins, along with RxSTS1OHClk_n,
RxSTS1OHFrame_n and RxSTS1OH_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 RxSTS1OH_n output pins.
These output pins will toggle "High" coincident with the POH data as
it is being output via the RxSTS1OH_n output pins. Conversely,
these output pins will toggle "Low" coincident with the TOH data as it
is being output via the RxSTS1OH_n output pins.

Receive STS-1 TOH and POH Output Port - Output pin:
These output pins, along with RxSTS1OHSel_n, RxSTS1OHClk_n
and RxSTS1OHFrame_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 RxSTS1OHClk_n.
As a consequence, external circuitry receiving this data, should sam-
ple this data upon the rising edge of RxSTS1OHClk_n.
