TUPP-PLUS
鈥?Extracts tributary Path signal label into
internal registers and detects Change
Of tributary Path Signal Label
(COPSL) events for each tributary.
鈥?Detects tributary Path Signal Label
Mismatch (PSLM) and unstable
(PSLU) alarms.
鈥?Detects tributary unequipped defect
(UNEQ), tributary Path Defect
Indication (PDI-V), and the assertion
and removal of tributary extended
Remote Defect Indications (RDI).
鈥?Extracts and stores the tributary size
(SS) bits.
鈥?Calculates and compares the tributary
Path BIP-2 error detection code.
Accumulates the BIP-2 errors and
tributary Path Far-End Block Errors
(FEBEs) on a block or bit basis.
鈥?Supports in-band error reporting by
updating the FEBE, 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.
VT/TU Payload Processor/Performance Monitor
FEATURES
鈥?A configurable, multi-channel, payload
processor for alignment of SONET
Virtual Tributaries (VTs) or SDH
Tributary Units (TUs). 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, AU4,
AU3) synchronous payload envelope
frame rates through processing of the
lower level (VT6, VT3, VT2, VT1.5,
TU3, TU2, TU12, or 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 when
configured to operate in locked mode.
鈥?Independently-configurable incoming
and outgoing interfaces that operate in
byte-interface mode using a
19.44 MHz clock or in nibble-interface
mode using a 38.88 MHz clock.
鈥?Provides a generic 8-bit
microprocessor bus interface and a
standard 5-signal IEEE P1149.1 JTAG
test port.
鈥?Low power, +5 V, CMOS technology,
TTL-compatible inputs and outputs.
鈥?Available in a 160-pin Plastic Quad
Flat Pack (PQFP) package (28 by
28 mm).

PER-TRIBUTARY FUNCTIONS
鈥?Detects Loss Of Pointer (LOP) and
reacquisition.
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 (TIM) and unstable
(TIU) alarms.
