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.
