Ethernet into STS-12/STM-4 SONET/SDH Mapper TXC-04212 PRODUCT INFORMATION FEATURES
Eight 10/100 Mbit/s Ethernet ports, each using SMII interface Single 1000 Mbit/s Ethernet port, using parallel GMII interface (lead shared with SMII interfaces) Ethernet Management interface control configuration externally connected PHYs GMII Mux-mode allowing multiple concatenation groups from GMII Supports IEEE 802.3 flow control (Half Full-duplex) management statistics (RMON) 10/100/1000 Mbit/s Ethernet ports (100 Mbps full-duplex only) 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) IETF RFC2878, Point-to-Point Protocol (PPP) with Bridging Control Protocol (BCP) support Transparent HDLC processing Performs mapping/demapping encapsulated Ethernet frames into/from Order Virtual Concatenated Payloads High Order virtual contiguous concatenated payloads Dynamic bandwidth allocation using LCAS (ITU-T G.7042) High Order Virtual Concatenated payloads Glueless memory interface external SDRAMs Order Pointer processing 336/252 VT/TUs High Order Pointer processing STS-1/VC-3/ STS-3c/VC-4, STS-6c, STS-9c STS-12c/VC4-4c Byte-wide 77.76MHz /Drop Line Telecom interfaces Per-port Ethernet side SONET/SDH system side loopback system level diagnostics 16-bit wide microprocessor interface, selectable between Motorola Intel based driver provided (comparable with EtherMap-3) Boundary scan (IEEE 1149.1 standard) 3.3V +1.2V power supplies, tolerant leads
EtherMapTM-12 highly integrated, STS-12/STM-4 rate SONET/SDH device that provides mapping 10/100/1000 Mbps Ethernet traffic into SONET/SDH Transport structures. EtherMap-12 Ethernet side, either Eight 10/100 Mbps SMII interfaces independent 1000 Mbps GMII interface. Over-subscription allowed example mapping Gigabit Ethernet stream into either single VC-44c/STS12c SPE, multiple VC-4/STS-3c SPEs, multiple VC3s/STS-1 SPEs supported configuration built-in flow control mechanisms. STS-12/STM-4 front-end device standard byte wide 77.76 Telecom interface SONET processing includes High Order pointer tracking retiming, High Order processing performance monitoring along with complete High Order Order Virtual Concatenation with LCAS. Both VT/TV STS-1/VC-3 level noon-blocking cross connects available flexible data path grooming switching. device operates from 1.2V core 3.3V/IO power supplies. fully functional Device Driver available through TranSwitch Applications Engineering.
