This register is used to enable the processing of STS-1 #3 (TUG3 #3) 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 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 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. When in TU3 mode,
registers 60H and 67H reflect TU3 status and configuration, all other registers
relating to TUG2s and the tributaries within TUG2s are disabled; data written
