Part Number - S1201QFI22 Product Brief Revision 3.4 - February 2002 Datasheet Revision 3.1 CONGO STS-12c/STS-3c POS/ATM SONET MAPPER Features Processes SONET/SDH STS-12c/(STM-4/AU-4-4c) or STS-3c/STM-1 data streams with full duplex mapping of ATM cells or packets (PPP or LAPS) into SONET/SDH payloads. Terminates & generates SONET/SDH section, line, & path layers, with transport/section E1, E2, F1 and DCC overhead interfaces in both transmit and receive directions. Provides an 8-bit parallel line-side interface operating at 19.44/77.76 MHz, and a 16-bit Utopia Level 2 or POS-PHYTM Level 2 compatible system-side interface at 25/50 MHz. Generic 8-bit microprocessor interface for configuration, control, and status monitoring. Scrambling/descrambling (1+X6+X7) of SONET/SDH frame. Selectable self-synchronous scrambler implementing +1) polynomial for ATM and HDLC. (X43 PRODUCT BRIEF General Description The S1201 is a highly-integrated VLSI device that provides full-duplex mapping of PPP/LAPS encapsulated packets or ATM cells into STS-12c/AU-4-4c or STS-3c/AU-4 payloads. The S1201 supports full-duplex processing of SONET/SDH data streams with full section, line, and path overhead processing. The device supports framing pattern, scrambling/descrambling, alarm signal insertion/detection, and bit interleaved parity (B1/B2/B3) processing. Serial interfaces for SONET/SDH TOH overhead bytes are also provided. The S1201 provides a line-side interface that can operate at 622.08 Mb/s……
