FEATURES - Monolithic single channel STS192/STM-64 or quad channel STS48/STM-16 SONET/SDH Payload extractor/aligner. - Designed for use in interface applications operating at serial interface speeds of up to OC-192 rates: - single STS-192c (STM-64/ AU4-64c); - single STS-192 (STM-64/AU416c/AU4-4c/AU4/AU3) channelized to STS-1; - quad STS-48c (STM-16/AU4-16c); - quad STS-48 (STM-16/ AU4-4c/AU4/AU3); - pointer processing for STS-1, STS-3c, STS-12c, STS-24c, STS48c, and STS-192c traffic. - In single STS-192/STM-64 mode, supports a duplex 16-bit 622 MHz LVDS line side interface for direct connection to external clock recovery, - clock synthesis and serializerdeserializer ponents. In quad STS-48/STM-16 mode, supports four duplex 4-bit 622 MHz LVDS line side interfaces for direct connection to external clock recovery, clock synthesis and serializerdeserializer ponents. Standard OIF SFI-4 (16 x 622 Mbit/s) line side interface. Each channel provides termination for SONET Section, Line and Path overhead or SDH Regenerator Section, Multiplexer Section and High Order Path overhead. Provides a 16-bit 622 Mbit/s 8B10B encoded (777.7 MHz) ADD and DROP serial Tele Bus interface for grooming a single STS-192/STM-64 stream. Provides four 4-bit 622 Mbit/s 8B10B encoded (777.7 MHz) ADD and DROP serial Tele Bus interfaces for grooming four STS-48/STM-16 streams. - Maps SONET/SDH payloads to system timing, acmodating plesiochronous timing offsets between the line and system timing references, through pointer processing. - Provides STS-12 cross-connect capability for grooming traffic at the ADD and DROP Tele Bus interface. - The entire SONET/SDH transport overhead is extracted to and inserted from dedicated pins. Path BIP-8 error counts are extracted to dedicated pins. - Frames to the SONET/SDH receive stream, inserts framing bytes and STS identification into the transmit stream, and processes or inserts the transport overhead. - Interprets or generates the STS (AU) pointer bytes (H1, H2,...
