SONET/SDH TRIBUTARY UNIT PAYLOAD PROCESSOR / PERFORMANCE MONITOR
Accumulates TU3 tributary far end block errors (FEBE) on a bit or a block
basis, in internal registers.
•
•
Allows insertion of all-zeros or all-ones tributary idle code with unequipped
indication and valid pointer into any tributary under software control. Idle
tributaries are identified by an output signal.
Identifies outgoing tributaries that are in AIS state by an output signal. Allows
software to force the AIS insertion on a per tributary basis.
•
•
Inserts valid H4 byte and all-zeros fixed stuff bytes on the outgoing stream.
Remaining path overhead bytes (J1, B3, C2, G1, F2, Z3, Z4, and Z5) can be
configured to be set to all-zeros or to reflect the value of the corresponding
POH bytes in the incoming stream.
Inserts valid pointers, and all-zeros transport overhead bytes on the outgoing
stream with valid "TeleCombus" control signals when configured to operate in
locked mode.
•
Supports in-band error reporting by updating the FEBE, RDI and auxiliary
RDI bits in the V5 byte (G1 in TU3) with the status of the incoming stream.
•
•
•
•
•
Provides low maximum tributary processing delay of 33 µs for VT1.5, 25 µs
for VT2, 17 µs for VT3, and 9 µs for VT6 streams.
Verifies parity on the IC1J1 and ISPE signals and on the incoming data
stream and generates parity on the outgoing data stream.
May be used for multiframe synchronization or ring closure at the head-end
node of a SONET/SDH ring.
Operates in conjunction with the PM5344 SPTX SONET/SDH Path
Terminating Transceiver to align tributaries such that they can be switched by
the PM5371 TUDX SONET/SDH Tributary Unit Cross-Connect. Provides
backwards compatibility with the PM5361 TUPP SONET/SDH Tributary Unit
Payload Processor.
Independently configurable incoming and outgoing interfaces that operate in
byte interface mode from a single 19.44 MHz clock or in nibble interface
mode from a single 38.88 MHz clock.
