This register configures the STP functionality in the TUPP+622 that are related to
the outgoing data stream.
OCONCAT:
When set high, the OCONCAT bit configures the outgoing section of the STP
to operate in AU4 mode. When the OCONCAT bit is set low, the outgoing
section operates in AU3 mode (or equivalently, STS-1 mode).
Reserved:
The Reserved bit must be set low for correct operation of the TUPP+622.
OTMFH4:
The OTMFH4 bit selects the location of the corresponding OTMF in the
tributary multiframe. When OTMFH4 is set high, OTMF is pulsed high to mark
the H4 byte which indicates that the next AU3/4 or STS-1 frame is the first
frame of the tributary multiframe. When OTMFH4 is set low, OTMF marks the
third byte after J1.
OOP:
The OOP bit controls the parity placed on the corresponding outgoing parity
signal ODP. When OOP is set low, the parity of outgoing data stream OD[7:0],
together with ODP is even. When OOP is set high, the parity is odd.
