TUPP+622
VT/TU Payload Processor/Performance Monitor for 622 Mbit/s
FEATURES
The TUPP+622 chip offers the following
features:
鈥?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.
鈥?Provides independently-configurable
AU3/AU4 frame format on incoming
and outgoing directions.
鈥?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.
鈥?Provides for multiframe
synchronization or ring closure at the
head-end node in a SONET/SDH ring.
鈥?Optionally frames to the H4 byte in the
Path overhead to determine tributary
multiframe boundaries.
鈥?Inserts valid pointers, and all-zeros
transport overhead bytes on the
outgoing stream with valid
鈥淭elecombus鈥?control signals.
鈥?Independently-configurable incoming
and outgoing interfaces that operate in
19.44 MHz or 77.76 MHz byte
interface modes.
鈥?Provides a standard JTAG test port for
boundary scan board test purposes.
鈥?Provides a generic 8-bit
microprocessor bus interface.
鈥?Low power 2.5V CMOS core logic/3.3V
TTL compatible inputs and outputs
鈥?Available in a 304-pin SBGA package.
鈥?Supports industrial temperature range
(-40擄C to 85擄C) operation.
鈥?Extracts and serializes the entire
tributary Path overhead of each
tributary.
鈥?Detects tributary elastic store
underflow and overflow errors.
鈥?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.
鈥?Detects tributary Path Signal Label
Mismatch and unstable alarms.
鈥?Extracts tributary Path signal label into
internal registers and detects Change
of Tributary Path Signal Label events
for each tributary.
鈥?Detects tributary unequipped defect,
tributary Path Defect Indication, and
the assertion and removal of tributary
extended Remote Defect Indications.
鈥?Extracts and stores tributary size bits.
鈥?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.
鈥?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.
鈥?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.
鈥?Under software control, allows
insertion of all-zeros or all-ones
tributary idle code with unequipped
indication.
APPLICATIONS
Use the TUPP+622 chip in the following
applications:
鈥?SONET/SDH Add/Drop and Terminal
Multiplexers
鈥?SONET/SDH Broadband
Cross-Connects
鈥?SONET/SDH and ATM Test Equipment
