outgoing tributaries if the pointer interpreter detects tributary path AIS on the
corresponding incoming tributary.
The common bus interface allows microprocessor access to the registers within
each tributary payload processor. It is used during normal operation and also
during production test. It forms part of the overall microprocessor interface of the
TUPP .
Microprocessor Interface
The microprocessor interface block provides normal and test mode registers, and
the logic required to connect to the microprocessor interface. The normal mode
registers are required for normal operation, and test mode registers are used to
enhance the testability of the TUPP . Tributary based normal mode registers are
arranged in order of transmission; TU #1 in TUG2 #1 is the first tributary
transmitted, while TU #4 in TUG2 #7 is the last. The register set is accessed as
follows:
