  6. MW-SDH IDU Standard PDH 1+0 Configuration

  7. SDH 1+0 Configuration • Part number: IDU-SO (STM-1 Optical, 1+0) or IDU-SW (STM-1 Electrical, 1+0) • Consists of • Chassis, Backplane • 5 modules • CCM-4800: Power Supply Module • CCM-4500: Controller Module • CCM-4100: Standard I/O Module • CCM-4600: Modem and IF/Telemetry Module • CCM-4155 or -4156: STM-1 Optical or Electrical Mini IO Module

  8. SDH 1+0 Capability: IDU-SO (STM-1 Optical, 1+0) or IDU-SW (STM-1 Electrical, 1+0) Dependent on available bandwidth: can adjust for operating bandwidth Payload Options (hardware is always available in unit) 100BaseTX Ethernet: scalable (from 1 – 100 Mbps) 1-16 x E1/T1: 2 x E1 (RJ-48C), 14xE1 (Molex 60-pin high density) STM-1 Optical or Electrical Skyway’s “Mode Configurator” tool to create any combination (assuming available bandwidth) Examples include STM-1 + 1 Mbps scaled Fast Ethernet STM-1 + 1 E1 Other combinations that allow operation in 28/30 MHz bandwidth SDH 1+0 Configuration

  9. SDH 1+1 Configuration • Part number: IDU-SO (STM-1 Optical, 1+1) or IDU-SW (STM-1 Electrical, 1+1) • Consists of • Chassis, Backplane • 7 modules • CCM-4800: Power Supply Module, Qty2 each (for redundancy) • CCM-4500: Controller Module • CCM-4100: Standard I/O Module • CCM-4600: Modem and IF/Telemetry Module, Qty2 each (for redundancy) • CCM-4155 or -4156: STM-1 Optical or Electrical Mini IO Module

  10. 2+0 or East/West Configuration • Consecutive point architecture achieved with only a single 1 RU chassis at each location • In this configuration the IDU contains 2 Power Supply Modules and 2 Modem/IF Modules • One Modem/IF is referred to as the west modem and the other as the east modem • The IDU is connected to two ODUs, one broadcasting/receiving in one directing of the ring architecture and the other broadcasting/receiving in the other direction

  11. Multi-hop Repeater with D/I Config • This configuration provides individual 1 + 1 link protection as well as the full-scale protection inherent in the consecutive point architecture • At each location within the network, data may be dropped or inserted • Front panel connections for drop/insert capability are provided • In this configuration each IDU contains 2 Power Supply Modules and 2 Modem/IF Modules

  12. Diversity mode: the link between each pair of modems is the same, providing complete redundancy This arrangement requires bandwidth for both links and non-interference between the links, but it provides hitless receive and transmit switching The IDU supports both frequency and spatial diversity Frequency diversity: two frequencies are used Spatial diversity: two non-interfering paths are used In either case, the proprietary framer chooses the best, or error-free, data stream and forwards it to the Line Interface Units (LIUs) 1+1 Protection: Diversity

  13. Non-diversity mode: One ODU at each location transmits to both two ODUs at the other location Does not require the extra bandwidth or interference protection of diversity mode Provides hitless receive switching and hot standby IDU automatically switches transmit ODU upon appropriate ODU alarm or ODU interface error, minimizing transmit outage time The power supply, ODU, IF/telemetry and modem are protected The digital framing and LUIs are not 1+1 Protection: Non-Diversity

  14. PDH (IDU-PB 1+0) to Super PDH Additional 16xE1 + standard 16xE1 = 32xE1 CCM-4132: 16E1 Expansion IO Module Software key to enable 32xE1 operation Status of 16E1 Expansion IO Module (CCM-4132) Integration complete SDH (IDU-SO or IDU-SW) with STM1-to-E1 Mux/Demux CCM-4132: 16E1 Expansion IO Module CCM-4100X: Standard IO with enhanced operation Software key to enable STM-1 to E1 (up to 32E1) Mux/Demux operation Status of STM1-to-E1 Mux/Demux Integration in progress IDU: Options

  15. Provides any-to-any connection between Front-panel E1/T1 ports (16 or 32) STM-1 payload (63xE1 or 84xT1) East Radio Link (63xE1 or 84xT1) West Radio Link (63xE1 or 84xT1) Mapping configurations may be developed in Excel and uploaded to the IDU. Mappings are selected on the IDU via a drop-down box. Up to 32 pre-defined (via Excel) mappings may be specified A custom mapping can be edited directly on the IDU E1/T1 Cross-Connect Switch

  16. STM-1 MUX/DEMUX • STM-1 Multiplex/Path Terminating • Mux/Demux • 63xE1 • 84xT1 • E1/T1 Cross-Connect Switch • Any-to-Any connection of E1/T1 signals • 1+0/1+1 operation • Up to 63xE1or 84xT1 over-the-air • 2+0 operation • Up to 126xE1 or 168xT1 over-the-air

  17. Additional Options • Skyway would like Customer feedback on other network option cards • CCM-4132: 16E1/T1 Expansion IO • In prototype verification • CCM-4150: DS-3/E3/STS-1 • Single DS-3 or E3 or STS-1 • CCM-4xxx: Multi DS-3/E3/STS-1 • 3 x DS-3, 4xE3, 3xSTS-1

  18. 16/32 E1 Crosspoint Capability • The IDU cross point switch provides any-to-any E1/T1 routing between the front-panel ports, east and west RF links. • Flexible channel mapping allows pointand- click selection of predefined routings or custom routing. • Custom routing selections may be uploaded to the IDU via FTP.

  19. 16/32 E1 Crosspoint Capability • Add/Drop Example: E1/T1s may be dropped from east or west to the front-panel ports.

  20. Scalable SDHSTM-1 Mux/Demux Capability • The IDU STM-1Mux/Demux providescapability to demultiplex63xE1 (84xT1) PDHsignals from the SDHsignal. • The demultiplexedE1/T1s are routed viathe crosspoint switch toeast, west, or frontpanel. • Enhanced IO (CCM-4120)Module isrequired for this function

  21. Modules Introduction • Outdoor unit（ODU） • Power • U/D transducer • HPA • LNA • OMT
