WHO: LuxN Inc. (www.luxn.com), the premier provider of intelligent,
multi-service, optical access solutions. LuxN will showcase live, interactive
demonstrations of its optical network access solutions at the Networld+Interop
conference. LuxN's WavSystem(TM) solutions have set new standards for optical
network access. With LuxN, local service providers and enterprise companies are
now able to cost-effectively extend optical networks from metropolitan points
of presence to enterprise customer premises. LuxN's solutions are available
today and are being used by customers to experience the benefits of advanced
optical-access technology. Offering a new vision of optical access, LuxN is
providing the solutions for tomorrow's all-optical Internet. WHAT: LuxN, in
conjunction with Riverstone Networks (www.riverstonenet.com), the leader in
high-speed metropolitan area network infrastructure, will showcase live data
being transmitted across the show floor through optical fiber at Gigabit
Ethernet speeds. Using a multimedia video stream, traffic will originate at
LuxN's booth (#7933), and be passed to a Riverstone RS 2000 switch router. The
Gigabit Ethernet data stream will then go to a LuxN WavStation(TM) for
transport across the show floor using approximately 800 feet of single-mode
optical fiber. In the Riverstone booth (#4531) the traffic will arrive at a
LuxN WavFarer(TM), be passed to a Riverstone 8600 switch router and presented
as a multimedia data stream on a video display.    In addition, technical
presentations of LuxN's ColorSIM(TM) network monitoring solution will be
provided in LuxN's (invitation-only) Technology Suite. ColorSIM, integrated
into LuxN's WavSystem line of optical access solutions, gives carriers and
service providers the ability to continuously monitor each lambda of their
network without the need for separate bit error rate testing equipment. It
employs a unique, non-intrusive, "wrapperless" methodology that does not tap
any portion of the optical power and is bit-rate and protocol independent. WHY:
Service providers, as well as enterprise companies, are constantly faced with
network challenges - the need for faster speeds, higher bandwidth, data
integrity and more. By engaging an optical network, service providers can
deliver new, high bandwidth, multi-protocol services while maximizing their
optical fiber assets to generate new revenues. Enterprise end-users can
dramatically upgrade their public network access performance while enjoying the
advantages of using multiple communications protocols such as Fibre Channel,
Gigabit Ethernet and/or SONET. In addition to providing unique monitoring
capabilities without the need for separate test equipment, ColorSIM provides
users the ability to forecast impending problems in their networks so that
serious data transmission problems can be avoided. It promises to be an
important tool for monitoring Quality of Service (QoS) agreements. WHEN: The
Networld+Interop 2000 Conference will be held September 26-28, 2000. The LuxN
Optical Network demonstration will be shown live throughout the conference.
Technical presentations and demonstrations of LuxN's ColorSIM will be shown by
appointment only. WHERE: The Gigabit Ethernet Interoperability demonstration
will be shown in LuxN's booth (#7933) and in Riverstone Networks' booth
(#4531). Preview LuxN's ColorSIM network monitoring solution in the LuxN
Technology Suite at the Omni Hotel, across from the show floor. The
Networld+Interop 2000 Conference will be held at the Georgia World Congress
Center in Atlanta, Georgia. More information is available online at:
