TUPP+622
VT/TU Payload Processor/Performance Monitor for 622 Mbit/s
FEATURES
The TUPP+622 chip offers the following
features:
• A configurable, multi-channel, payload
processor for alignment of SONET
Virtual Tributaries or SDH Tributary
Units in an STS-12/STM-4 or four
STS-3/STM-1 byte serial data streams.
Configurable to process any legal mix
of tributaries.
• Provides independently-configurable
AU3/AU4 frame format on incoming
and outgoing directions.
• Compensates for pleisiochronous
relationships between incoming and
outgoing higher level (STS-1 to AU3)
synchronous payload envelope frame
rates through processing of the lower
level (VT6 to TU11) tributary pointers.
• Provides for multiframe
synchronization or ring closure at the
head-end node in a SONET/SDH ring.
• Optionally frames to the H4 byte in the
Path overhead to determine tributary
multiframe boundaries.
• Inserts valid pointers, and all-zeros
transport overhead bytes on the
outgoing stream with valid
“Telecombus” control signals.
• Independently-configurable incoming
and outgoing interfaces that operate in
19.44 MHz or 77.76 MHz byte
interface modes.
• Provides a standard JTAG test port for
boundary scan board test purposes.
• Provides a generic 8-bit
microprocessor bus interface.
• Low power 2.5V CMOS core logic/3.3V
TTL compatible inputs and outputs
• Available in a 304-pin SBGA package.
• Supports industrial temperature range
(-40°C to 85°C) operation.
• Extracts and serializes the entire
tributary Path overhead of each
tributary.
• Detects tributary elastic store
underflow and overflow errors.
• Stores and processes 16-byte or
64-byte format tributary Path trace
messages (tributary trail trace
identifiers). Detects tributary Path
Trace Mismatch and unstable alarms.
• Detects tributary Path Signal Label
Mismatch and unstable alarms.
• Extracts tributary Path signal label into
internal registers and detects Change
of Tributary Path Signal Label events
for each tributary.
• Detects tributary unequipped defect,
tributary Path Defect Indication, and
the assertion and removal of tributary
extended Remote Defect Indications.
• Extracts and stores tributary size bits.
• Calculates and compares the tributary
Path BIP-2 error detection code.
Accumulates the BIP-2 errors and
tributary Path Remote Error Indications
on a block or bit basis.
• Supports in-band error reporting by
updating REI, RDI, and auxiliary RDI
bits in the V5 byte (G1 in TU3) with the
status of the incoming stream.
• Optionally generates tributary Path AIS
on the detection of LOP, loss of
tributary multiframe, trace identifier
unstable, trace identifier mismatch,
signal label unstable, and/or signal
label mismatch. Also allows software
to force AIS insertion.
• Under software control, allows
insertion of all-zeros or all-ones
tributary idle code with unequipped
indication.
