PM5312 STTX PMC-Sierra,Inc. SONET/SDH Transport Overhead Terminating Transceiver FEATURES • Inserts line Far-End Block Errors (FEBEs) into the Z2 growth byte based on received B2 errors. • Accumulates near-end errors (B1 and B2) and far-end errors (Z2). • Extracts and inserts the order wire channels (E1 and E2). • Extracts and inserts the data communications channels (D1-D3 and D4-D12). • Extracts and inserts the section user channel (F1). • Extracts and inserts the Automatic Protection Switch (APS) channel (K1 and K2). The receive APS bytes are also filtered and extracted into internal registers. • Detects Loss Of Signal (LOS), Out Of Frame (OOF), Loss Of Frame (LOF), Far-End Receive Failure (FERF), line Alarm Indication Signal (AIS), and protection switching byte failure alarms. • Inserts FERF and AIS in the transmit stream. • Provides LOS insertion, framing pattern error insertion, and coding • Monolithic, SONET/SDH Transport Overhead Terminating Transceiver for use in STS-1, STS-3 (STM-1), or STS-12 (STM-4) applications. • Operates in STS-1 bit-serial mode, STS-1 byte-serial mode, STS-3/STM-1 byte-serial mode, or STS-12/ATM-4 byte-serial mode. • Compatible with PM5355 S/UNI-622 physical layer interface, PM5344 SPTX SONET/SDH Path Terminating Transceiver, and with commercially available 622 Mbit/s serial-to-parallel conversion devices. • Performs byte-interleaved multiplexing of lower-rate, drop-side, SONET/SDH data streams. • Optionally inserts the framing bytes (A1 and A2) and the STS identification bytes (C1) in to the transmit stream. • Performs frame synchronous descrambling and scrambling. • Compares the bit-interleaved parity error detection codes (B1 and B2) for the receive stream. Inserts B1 and B2 in the transmit stream. violation insertion (B1 and B2) for diagnostic purposes. B1 and B2 error can also be generated “on-the-fly” using an error insertion mask. • Provides a transmit and receive ring control port, allowing alarm and maintenance signal control and status to be passed between mate STTXs for applications in ring-based add/drop multiplexers. • Low power, +5 V, CMOS technology. Device has TTL/CMOS-compatible inputs and outputs. • Available in a high performance 208pin copper slugged (28 by 28 mm) Plastic Quad Flat Pack (PQFP) package.
