New Larscom WAN Access Product Enables Seamless Multinational Connectivity Larscom's New Orion 4000 is an Industry-First Solution for the Economical, High-Density Transport of Multiple International (E1) Data Streams Across U.S. T1 Networks NEWARK, Calif., Feb. 25 /PRNewswire-FirstCall/ -- Responding to the increasing globalization of business, Larscom today announced that it has raised-the-bar in multinational connectivity with a new version of its popular Orion 4000 multiplexer that contains a unique T2E844 module. For the first time, carriers now have a centralized, high-density solution for transporting international data streams (up to 32 E1 connections per system) across traditional U.S. T1 networks efficiently and cost-effectively. The new, modular Orion 4000 is the only solution available today that can act as a gateway for this type of service in the Central Office -- supporting multiple customers and locations through a single, chassis-based system -- with a single-point-of-management for all global communications. The Orion 4000 is designed to streamline communications for today's enterprises that conduct business on a global basis or those that, increasingly, are utilizing offshore call centers or engineering operations. The challenge, in these types of global situations, is transporting data from international E1 lines (2 Mbps) across U.S. based T1 access lines (1.5 Mbps) because of the difference in the amount of data each standard accommodates. Inverse multiplexing -- a technology that Larscom pioneered and that splits a single high-speed data stream into two, smaller streams then reassembles the data at the other end -- is a cost-effective and simple solution to this problem. "Many of our global carrier customers are required to offer services for their business customers with multinational operations," said Gurdip Jande, vice president of marketing at Larscom. "Until now, however, there just wasn't a cost-effective, high-density solution to accommodate multiple customers' needs in a single system for the Central Office. Combined with our Mega-T241 inverse multiplexer at the customer premise, carriers have an economical, end-to-end solution for international service delivery." End-to-End Global Access Solution The new Orion 4000 is next step in Larscom's global access solutions strategy, which also includes the Mega-T241. The Mega-T241 is an inverse multiplexer that carries a single E1 data stream across two T1 lines between the Central Office and a customer site. The Orion 4000, with its unique T2E844 module, is optimized for the carrier's Central Office to deliver multiple E1 services, including E1 PBX, over T1 facilities. Available today, the Orion 4000 offers an energy-efficient, space-saving design. Ittransparently supports any type of data and can accommodate any standard encoded protocol such as Multilink Point-to-Point Protocol (MLPPP), Multilink Frame Relay (MFR), as well as other new, emerging high capacity services being deployed worldwide. The product is a high-density aggregation solution that supports multiple global customers and locations through a single, point-of-management, capitalizing on the operational savings that comes with centralized alarms management, network statistics, transmission parameters, and provisioning.
