SONET/SDH TRIBUTARY UNIT PAYLOAD PROCESSOR FOR 622 MBIT/S
INTERFACES
• Configurable to process 16-byte or 64-byte format tributary path trace
messages (tributary trail trace identifiers).
• Optionally frames to the H4 byte in the path overhead to determine tributary
multiframe boundaries. Inserts internally generated H4 bytes with leading
logic 1 bits into the outgoing administrative units.
• Extracts and serializes the entire tributary path overhead of each tributary into
lower speed serial streams.
• Extracts tributary size (SS) bits of each tributary into internal registers.
• Detects loss of pointer (LOP) and re-acquisition for each tributary and
optionally generates interrupts.
• Detects tributary path alarm indication signal (AIS) and return to normal state
for each tributary and optionally generates interrupts.
• Detects tributary elastic store underflow and overflow errors and optionally
generates interrupts.
• Extracts tributary path trace message (trail trace identifier) of each tributary
into internal buffers.
• Provides individual tributary path trace message buffer that holds the
expected message and detects tributary path trace mismatch (trail trace
identifier mismatch) alarms (TIM) and return to matched state for each
tributary and optionally generates interrupts.
• Detects tributary path trace unstable (trail trace identifier unstable) alarms
(TIU) and return to stable state for each tributary and optionally generates
interrupts.
• Extracts tributary path signal label for each tributary into internal registers and
detects change of tributary path signal label events (COPSL) of each tributary
and optionally generates interrupts.
• Provides individual tributary path signal label register that hold the expected
label and detects tributary path signal label mismatch alarms (PSLM) and
return to matched state for each tributary and optionally generates interrupts.
