This register is used to enable the processing of STS-1 #1 (TUG3 #1) and
configure the major operational modes of VTPP #1.
OTUG3:
When set high, the OTUG3 bit configures the tributary payload processor to
process a TU3 or TUG2s that have been mapped into a TUG3 in the outgoing
data stream. When set low, the tributary payload processor defaults to
processing TUG2s that have been mapped into a VC3, or equivalently, VT
groups that have been mapped into an STS-1.
ITUG3:
When set high, the ITUG3 bit configures the tributary payload processor to
process a TU3 or TUG2s that have been mapped into a TUG3 in the
incoming data stream. When set low, the tributary payload processor defaults
to processing TUG2s that have been mapped into a VC3, or equivalently, VT
groups that have been mapped into an STS-1.
TU3:
When set high, the TU3 bit configures the tributary payload processor to
process a single TU3 that has been mapped into a TUG3. The programming
of the ITUG3 and OTUG3 bits are ignored. Both the incoming and outgoing
streams are affected simultaneously by the TU3 bit. In TU3 mode, registers
