This register is used to configure the major operational modes of tributary
payload processor #1.
OTUG3:
When set high, the OTUG3 bit configures the tributary payload processor to
process 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 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. When the TU3 bit
is set high, the ITUG3 and OTUG3 bits should be set low. Both the incoming
and outgoing streams are affected simultaneously by the TU3 bit. When in
TU3 mode, registers 20H and 27H reflect TU3 status and configuration, all
other registers relating to TUG2s and the tributaries within TUG2s are
