Siemens to deliver Unisphere's ERX Edge Routing Switch and Seabridge's
Attane XpressPass Broadband Concentrator for Nextra's Next-Generation

Nextra AS, the Norwegian Communication Service Provider, has awarded Siemens
Information and Communication Networks group (ICN) an order, worth millions
of euros, to supply edge routing and a broadband access solution for its
next generation network. The order is part of a Pan-European framework
agreement. Siemens, together with its affiliates Unisphere Networks and
Seabridge, delivers Edge Routing Switches and Broadband Access

The ERX 700 Edge Routing Switch from Unisphere provides broadband xDSL
access to the IP network in its function as a broadband remote access server
(BB RAS). The BB RAS is the point of entry into the Internet, used by
subscribers to dial into their service provider's network.
The Attane XpressPass Broadband Concentrator from Seabridge aggregates
connections at the access point and grooms xDSL traffic between the DSLAM
and the ERX 700 BB RAS, greatly enhancing network scalability.

Nextra will install the ERX and the XpressPass to support new DSL services
in cities throughout Norway. Nextra then expects to move forward with a
larger ERX/XpressPass supported Pan-European rollout following deployment of
the Norwegian network later in 2001.

"In a tight selection process, we chose the Siemens solutions because it was
obvious that the ERX and XpressPass systems had been designed with the needs
of carrier-class next-generation networks in mind, and because of the
expertise in IP networking that Siemens brought with them. With the ERX and
XpressPass, we have the ability to meet the demands of the increasing
Internet traffic that we expect in the next several years," says Per Björk,
CTO of Nextra AS. "In particular, we are very excited about the traffic
management capabilities that the ERX and XpressPass gives us, which will
allow us to optimize our network and more easily bring to our customers
cutting edge services."

"We are excited about this opportunity to work with an innovative company
such as Nextra in bringing new telecommunications services to the European
marketplace," said Jim Dolce, CEO, Unisphere Networks, Inc. "This
announcement showcases the power of Unisphere's ERX as well as the strengths
the combined Siemens/Unisphere relationship brings, and the commitment of
Siemens to bringing next-generation technology to service providers

"We are glad to be a part of Nextra's solution for its broadband access
network," said Yehuda Armoni, CEO of Seabridge, Ltd. Nextra's choice of the
XpressPass further strengthens Seabridges standing as an industry leader in
the optimization of broadband networks."

"Siemens is proud to be a partner for Nextra in Europe" said Magne
Orderløkken, Director IP and Broadband Networks Siemens AS. "Nextra is an
innovative communication service provider with high ambitions, and we are
glad to provide Nextra with leading edge products and support."
