VT/TU Payload Processor/Performance Monitor

TUPP-PLUS

FEATURES

• 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.

• Provides independently-configurable

AU3/AU4 frame format on incoming

and outgoing directions.

• 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.

• 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 when

configured to operate in locked mode.

• 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.

• Provides a generic 8-bit

microprocessor bus interface and a

standard 5-signal IEEE P1149.1 JTAG

test port.

• Low power, +5 V, CMOS technology,

TTL-compatible inputs and outputs.

• Available in a 160-pin Plastic Quad

Flat Pack (PQFP) package (28 by

28 mm).

PER-TRIBUTARY FUNCTIONS

• Detects Loss Of Pointer (LOP) and

reacquisition.

• 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 (TIM) and unstable

(TIU) alarms.

• Extracts tributary Path signal label into

internal registers and detects Change

Of tributary Path Signal Label

(COPSL) events for each tributary.

• Detects tributary Path Signal Label

Mismatch (PSLM) and unstable

(PSLU) alarms.

• Detects tributary unequipped defect

(UNEQ), tributary Path Defect

Indication (PDI-V), and the assertion

and removal of tributary extended

Remote Defect Indications (RDI).

• Extracts and stores the tributary size

(SS) bits.

• 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.

• 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.

• 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.

APPLICATIONS

• SONET/SDH Add/Drop and Terminal

Multiplexers

• SONET/SDH Broadband Cross-

Connects

• SONET/SDH and ATM Test
