Product Brief October 1999 TDAT04622 TDAT04622 SONET/SDH 155/622 Mbits/s Data Interface Features s Point-to-point path termination device for interface termination. s Versatile IC supports 155/622 Mbits/s SONET/ SDH interface solutions for packet over SONET (POS), asynchronous transfer mode (ATM), or simplified data link (SDL) for data over fiber applications. s Supports point-to-point and multi-PHY UTOPIA. s Low-power 3.3 V operation, CMOS technology. s High-speed I/O is LVPECL. All other logic has 5 V tolerant TTL-level inputs. s 40 °C to +85 °C temperature range. s - ITU-T G.707: Network Node Interface for the Synchronous Digital Hierarchy. - ITU-T G.803: Architecture of Transport Networks Based on the Synchronous Digital Hierarchy. - T1.105: SONET-Basic Description including Multiplex Structure, Rates and Formats. - T1.105.02 SONET-Payload Mappings. - T1.105.03 SONET-Jitter at Network Interfaces. - T1.105.06 SONET Physical Layer Specifications. - T1.105.07 SONET-Sub-STS-1 Interface Rates and Formats Specification. - ITU-T I.432: B-ISDN User-Network InterfacePhysical Layer Specification. - IETF RFC 1619: PPP over SONET/SDH. - IETF RFC 1661: The Point-to-Point Protocol (PPP). - IETF RFC 1662: PPP in HDLC-like Framing. 600 LBGA package. SONET/SDH Interface s Termination of quad STS-3/STM-1 or singlechannel STS-12/STM-4 STS-12/STM-4. s s Data Processing s Supports overhead processing for transport and path overhead bytes. Provisionable data engine supports payload insertion/extraction and CRC-16/-32 CRC-16/-32 generation/verification for ATM cell or PPP, SDL, or HDLC streams. s Optional insertion and extraction of overhead bytes via serial overhead interface. Maintains counts for cell/packet traffic (e.g., total number of cells, number of discarded cells). s Integrated UTOPIA Level 2- and UTOPIA Level 3compatible ATM physical layer interface with packet extensions for test and operations. s Insertion and extraction of up to four separate data channels in STS-3/STM-1, and one data channel in STS-12/STM-4 STS-12/STM-4. s Compliant with 1998: ATM Forum, ITU standards, and IETF standards. s Full path termination and SPE extraction/insertion. s SONET/SDH compliant condition and alarm reporting. s Handles all concatenation levels of STS-3c through STS-12c, STM-1 through STM-4. s Built-in diagnostic loopback modes. s Compliant with the following Bellcore, ANSI*, and ITU standards: - GR-253 GR-253 CORE: SONET Transport Systems: Common Generic Criteria. * ANSI is a registered trademark of American National Standards Institute, Inc. Microprocessor Interface s 16-bit address and 16-bit data interface with up to 66 MHz read and write access. s Compatible with most industry-standard processors.
