SONET/SDH TRIBUTARY UNIT PAYLOAD PROCESSOR FOR 622 MBIT/S
INTERFACES
1
FEATURES
• Configurable, multi-channel, payload processor for aligning SONET virtual
tributaries (VTs) (SDH tributary units, TUs) in an STS-12 or four STS-3 (an
STM-4 or four STM-1) byte serial data streams.
• Four TUPP+622 may be used in parallel to support STS-48 (STM-16)
applications.
• Transfers all incoming tributaries in the twelve STS-1 synchronous payload
envelopes of an STS-12 or four STS-3 byte serial streams to the
corresponding twelve STS-1 synchronous payload envelopes of an outgoing
STS-12 or four outgoing STS-3 byte serial streams.
• Transfers all incoming tributaries in the four AU4 or twelve AU3 administrative
units of an STM-4 or four STM-1 byte serial streams to the corresponding four
AU4 or twelve AU3 administrative units of an outgoing STM-4 or four outgoing
STM-1 byte serial streams.
• 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.
• Provides software configurable offset between the payload frame boundaries
and the transport frame boundary on a per STS-3 or STM-1 basis.
• Optionally bypasses the tributary pointer interpretation function. Tributary
payload frame boundaries and payload bytes are identified by signals
coincident with the incoming data stream.
• Configurable to process any legal mix of VT1.5, VT2, VT3, VT6, TU11, TU12,
TU2, or TU3 tributaries. 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.
