Anaheim, California-based Fujitsu Business Communication Systems Inc has announced support for the soon-to-be released IMA Inverse Multiplexing over Asynchronous Transfer Mode standard. The ATM Forum is nearing completion of the new Inverse Multiplexing specification, which sets the stage for new, standardized inverse multiplexers. The standard is expected to be finalized by the end of the year. Fujitsu’s new Inverse Multiplexing module for the StarPath 5000 access concentrator is designed to enable service providers and corporations to extend their wide area network ATM services using low-cost 1.544Mbps DS-1 lines, as opposed to more expensive 45Mbps DS-3 facilities. The new DS-1/E-1 Asynchronous Transfer Mode User Network Interface module for the StarPath 5000 access concentrator will require no Inverse Multiplexing upgrades says the company. Customers will have access to eight ports per board, or Inverse Multiplexing-based connections up to 12Mbps on one board. In addition, the StarPath 5000 offers a traffic management architecture called Intellistream to support its Inverse Multiplexing board. It uses traffic shaping to maximize legacy and ATM bandwidth generated from voice, data and video applications, and to reduce costs. The Star Path 5000’s Inverse Multiplexing-based DS-1/E-1 module is scheduled for release by the end of the year. Prices have not yet been set.
