This set of registers reports the status and configures the operational modes of
TU #4 in TUG2 #1 to TUG2 #7. These registers have no effect in TU3 mode.
When the corresponding TUG2 tributary group is configured to TU2 (VT6), VT3
or, TU12 (VT2) mode, the associated register in this set has no effect.
IPAIS:
The IPAIS bit enables the insertion of path AIS for tributary TU #4 in the
corresponding TUG2. Tributary path AIS is inserted by forcing all ones into all
tributary bytes. The IPAIS bit has no effect when IIDLE is set high.
IIDLE:
The IIDLE bit enables the insertion of path idle for tributary TU #4 in the
corresponding TUG2. When IIDLE is set high, tributary payload bytes,
including V5 is replaced by an all-zero code. The V5 byte is set to all-zero to
yield correct BIP-2 and to indicate tributary unequipped. The outgoing pointer
is forced to zero. The IIDLE bit has precedence over the IPAIS bit.
DLOP:
The DLOP bit allows downstream pointer processing elements to be
diagnosed. When DLOP is set high, the new data flag (NDF) field of the
outgoing payload pointer in tributary TU #4 in the corresponding TUG2 is
