This register configures the TUPP-PLUS functionality that are related to the
incoming data stream.
ICONCAT:
When set high, the ICONCAT bit configures the incoming section of the
TUPP-PLUS to operate in AU4 mode. When the ICONCAT bit is set low, the
incoming section operates in AU3 mode (or equivalently, STS-1 mode).
ITMFEN:
When set high, the ITMFEN bit enables the TUPP-PLUS to use the ITMF
input signal to locate tributary multiframe boundaries. The H4 bytes in the
incoming data stream are ignored. When ITMFEN is set low, the H4 bytes
are used to locate the boundaries, and the ITMF signal is ignored.
ITMFH4:
The ITMFH4 bit selects the location of the ITMF in the tributary multiframe.
When ITMFH4 is set high, ITMF 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 ITMFH4 is set low, ITMF marks the third byte after J1.
ITMFH4 is ignored if ITMF is disabled by setting the ITMFEN bit low.
