ADM-1/4 SDH multi-service add/drop multiplexer

 SDH multi-service add/drop multiplexer


          SparkLight is a compact, powerful, highdensity and user-friendly, next generation SDH multiservice node for provisioning of PCM (voice, data), PDH (E1, E3), SDH (STM- 1, STM-4, STM-16) and Ethernet (FE, GbE) over SDH/xWDM.
          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.  
          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 pointto- 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 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.
