SONET/SDH TRIBUTARY UNIT PAYLOAD PROCESSOR / PERFORMANCE MONITOR
1
FEATURES
Configurable, multi-channel, payload processor for aligning SONET virtual
tributaries (VTs) or SDH tributary units (TUs) in an STS-3 or STM-1 byte
serial data stream.
•
•
•
•
Transfers all incoming tributaries in the three STS-1 synchronous payload
envelopes of an STS-3 byte serial stream to the three STS-1 synchronous
payload envelopes of an outgoing STS-3 byte serial stream.
Transfers all incoming tributaries in the single AU4 or three AU3 administrative
units of an STM-1 byte serial stream to the single AU4 or three AU3
administrative units of an outgoing STM-1 byte serial stream.
Compensates for pleisiochronous relationships between incoming and
outgoing higher level (STS-1, AU4, AU3) payload frame rates through
processing of the lower level (VT6, VT3, VT2, VT1.5, TU3, TU2, TU12, or
TU11) tributary pointers.
Configurable to process any legal mix of tributaries such as VT1.5, VT2, VT3,
VT6, TU11, TU12, TU2, or TU3. Each VT group or TUG2 can be configured
to carry one of four tributary types. TUG2s can be multiplexed into VC3s or
TUG3s. Each TUG3 can also be configured to carry a single TU3.
•
Independently configurable for AU3 or AU4 frame format on incoming and
outgoing 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 for each tributary
into lower speed serial streams.
•
Extracts tributary size (SS) bits for each tributary into internal registers.
•
•
Detects loss of pointer (LOP) and re-acquisition for each tributary and
optionally generates interrupts.
