| PMC-Sierra,Inc. PM5362 TUPP-PLUS * 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. VT/TU Payload Processor/Performance Monitor 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).

Detects tributary Path Trace Mismatch (TIM) and unstable (TIU) alarms.
