Ethernet into STS-3/STM-1 SONET/SDH Mapper TXC-04226 PRODUCT INFORMATION FEATURES
Supports eight 10/100 Mbit/s Ethernet ports, each using SMII interface Supports single 1000 Mbit/s Ethernet port, using parallel GMII interface (lead shared with SMII interfaces) Supports Ethernet Management interface control configuration externally connected PHYs. Supports IEEE 802.3 flow control management statistics (RMON) 10/100/1000 Mbit/s Ethernet ports Supports Ethernet frame encapsulation/decapsulation protocols: ITU-T G.7041, Generic Framing Procedure (GFP) ITU-T X.86/X.85, Link Access Procedure (LAPS) ITU-T Q.922, Link Access Procedure Frame Mode (LAPF) Performs mapping/demapping encapsulated Ethernet frames into/from order (VT1.5 SPE/VC-12) high order (STS-1 SPE/VC-3) virtual concatenated payloads Performs mapping/demapping encapsulated Ethernet frames into/from single contiguous concatenated (STS-3cSPE/VC-4) payload Supports optional LCAS processing (per ITU-T G.7042) high order virtual concatenated payloads Glueless memory interface external 64/128Mb SDRAMs Supports 84/63 VT/TU Order Pointer processing Supports High Order processing STS-1/VC-3/STS-3c/VC-4 Byte-wide parallel Drop Telecom interfaces Supports per-port Ethernet side SONET/SDH system side loopback system level diagnostics 16-bit wide microprocessor interface, selectable between Motorola Intel Boundary scan (IEEE 1149.1 standard) 3.3V +1.8V power supplies, tolerant leads 400-lead plastic ball grid array package
EtherMapTM-3 highly integrated device that provides mapping 10/100/1000 Mbit/s Ethernet into SONET/SDH STS-3/STM-1 Transport payloads. device supports connection eight 10/100 Mbit/s Ethernet ports, using SMII interfaces, single 1000 Mbit/s Ethernet port, using GMII interface. transmit direction, each port, received Ethernet frames encapsulated using either GFP, LAPS LAPF protocol. encapsulated Ethernet frames then mapped into configurable number virtual concatenated high order payloads, such VT1.5 SPE/ VC-12/STS-1 SPE/VC-3, contiguous concatenated payload such STS-3c SPE/VC-4. both high order payloads, required SONET/SDH bytes encapsulated Ethernet payload generated output using byte-wide parallel interface TranSwitch Telecom format. EtherMap-3 supports Drop timing modes. receive direction, each Ethernet port, configurable number high order payloads terminated, with complete byte processing virtual contiguous concatenated payloads. Using external SDRAM, alignment differential delay compensation received high order virtual concatenated payloads performed. Ethernet frames then decapsulated using GFP, LAPS LAPF protocol forwarded each Ethernet port. both high order virtual concatenated payloads, optional standards based LCAS processing provided allow hitless dynamic bandwidth adjustments. addition support full-rate Ethernet transfer, over-subscribed Ethernet transfers also supported using back pressure mechanisms order prevents frame loss.
