TUG2 #1 in TUG3 #1, TU#1 of TUG2 #1 in TUG3 #2, TU#1 of TUG2 #1 in TUG3
#3, TU#1 of TUG2 #2 in TUG3 #1, ... TU #1 of TUG2 #7 in TUG3 #3, TU #2 of
TUG2 #1 in TUG3 #1, ... TU #2 of TUG2 #7 in TUG3 #3, TU #3 of TUG2 #1 in
TUG3 #1, ... TU #4 of TUG2 #7 in TUG3 #3. Timeslot assignment on RADEAST
and RADWEST is unrelated to the configuration of the TUG2. Timeslots are
always reserved for four tributaries in every TUG2 even if it is configured for
tributaries with higher bandwidth than TU11, such as TU12. At timeslots devoted
to non-existent tributaries, for example, tributary 4 of a TUG2 configured for
TU12, RADEAST and RADWEST will be ignored.
Each tributary in the remote serial alarm port is allocated eight timeslots. The
first two timeslots, labeled B1 and B2 in Figure 67, reports the two possible BIP-2
errors in the tributary payload frame. An alarm contributing to remote defect
indications is reported in the third timeslot and is labeled D in Figure 67. The
timeslot labeled F report alarms contributing to remote failure indications. In
extended RDI mode, the D and F bits are considered as two bit codepoint and
will be reported on the RDI and RFI signals. Out of extended RDI mode, the D
and F bits are independent. The remaining four timeslots are unused and are
ignored.
