SparkLightADM-1/4 SparkLight ADM-1/4 NG SDH multi-service STM-1/4 Add/Drop multiplexer Various tributary interfaces on central module, many optional tributary modules, and a high capacity cross-connect matrix with stacking connectivity gives an opportunity to set up flexible and effective multi-service communication node. Integrated Ethernet L2 switch enables point-to-point and point-to-multipoint LAN traffic with many possibilities for traffic protection (on SDH or L2 switch level). Only radio module, outdoor unit and antenna are needed to establish SDH STM-1 microwave link. The management system with Java Web Start user interface, SNMP agent and OSPF router is built into the device. No additional equipment except a standard PC with built-in web browser is needed to set up the telemanagement system. SparkLight ADM-1/4 is a compact, powerful and user-friendly device for providing PDH (E1, E3), SDH (STM-1, STM-4) and Ethernet (FE, GE) over SDH networks. Used as an add/drop multiplexer on the SDH ring (or as a terminal multiplexer at the remote site), the SparkLight ADM-1/4 improves Ethernet bandwidth efficiency via GFP, VCAT and LCAS protocols, and also supports TDM mapping for termination at any point in the SDH network. Features • Compact 1U/2U high; 19"/ETSI compatible device. • 32xSTM-1 equivalent CC capacity. • Up to 2xSTM-1/4 electrical/optical line interfaces on the central module. • Up to 2xSTM-1 microwave radio line interfaces. • Upto40xE1 interfaces; 8xE1 on the central module. • Up to 3xE3 interfaces. • 6xFE interfaces on the central module. • 8xGFP mappers for P2P FE connections. • 1xGE interface on the central module. • Up to 2xESSI interfaces for equipment CC stacking. • GFP, VCAT, LCAS and embedded L2 switch for EoS. • Supports many different radio and SDH protection mechanisms. • Java Web Start and SNMP based integrated management. • xWDM ready. Benefits • Provides revenue-generating next generation Ethernet services while preserving investments in legacy SDH networks. • Optimized bandwidth utilization for Ethernet services using GFP VCAT, LCAS functionality. • Effective management integration using Java Web Start GUI and SNMP protocol transported by an embedded IP/OSPF telemanagement network. • Integrated optical/electrical and microwave radio SDH lines in the same device. • SFP modules for up to 120 km. • By stacking more ADM devices with ESSI interfaces a STM-1/4 non-blocking crossconnect node could be set up with no additional hardware. • Easy migration from TDM to IP • Combination of TDM and IP traffic. • Low OPEX/CAPEX. optical transmission system

Applications SparkLight ADM-1/4 is ideally suited for next generation IP services coexisting with legacy voice and TDM services in public telecommunications networks as well as networks of large corporations like: railways, highways, oil/gas distribution companies, government and private organizations.
