Transmit Overhead Enable Output indicator
This output pin functions as the Transmit Overhead Enable output indi-
cator for the transmit system side interface when the XRT94L31 is con-
figured to operate in STS-1/DS3/E3 mode, however, it functions as the
Transmit STS-1 Overhead Enable 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 pin, for one TxInClk period, just prior
to the instant that the Transmit Overhead Data Input Interface will be
sampling and processing an overhead bit.
If the local terminal equipment intends to insert its own value for an over-
head bit, into the outbound DS3 or E3 data stream, then it is expected to
sample the state of this signal, upon the falling edge of TxInClk. Upon
sampling the TxOHEnable_n signal "High", the local terminal equipment
should (1) place the desired value of the overhead bit, onto the TxOH_n
input pin and (2) assert the TxOHIns_n input pin. The Transmit Over-
head Data Input Interface block will sample and latch the data on the
TxOH_n signal, upon the rising edge of the very next TxInClk_n input
signal.
When configured to operate in STS-1 mode:
These output pins, along with TxOH_n, TxOHIns_n, TxOHFrame_n and
TxOHClk_n function as the Transmit Path Overhead (TxOH) Input Port.
These output pins will pulse "High" anytime the TxOH port is ready to
accept and process POH bytes. These output pins will be "Low" at all
other times.
