SONET/SDH TRIBUTARY UNIT PAYLOAD PROCESSOR FOR 622 MBIT/S
INTERFACES
• Detects tributary path signal label unstable alarms (PSLU) and return to stable
state for each tributary and optionally generates interrupts.
• Detects tributary unequipped defect (UNEQ) and tributary path defect
indication (PDI-V).
• Detects assertion and removal of tributary extended remote defect indications
(RDI) for each tributary and optionally generates interrupts.
• Calculates and compares the tributary path BIP-2 error detection code for
each tributary and configurable to accumulate the BIP-2 errors, on block or bit
basis, in internal registers.
• Calculates and compares the TU3 path BIP-8 error detection code for each
TU3 stream and accumulates the BIP-8 errors, on block or bit basis, in
internal registers.
• Accumulates TU3 tributary remote error indications (REI) 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 (H1, H2), framing bytes (A1, A2), and all-zeros transport
overhead bytes on the outgoing stream with valid "TeleCombus" control
signals.
• Supports in-band error reporting by updating the REI, RDI and auxiliary RDI
bits in the V5 byte (G1 in TU3) with the status of the incoming stream.
