Riverstone Promotes Interoperable Multi-Vendor Carrier Ethernet
Infrastructure Solutions
ADVA Optical Networking and BTI Photonic Systems Join Riverstone's Ethernet
Edge Alliance Program 


SANTA CLARA, Calif., May 24  /PRNewswire-FirstCall/ -- Carrier Ethernet pioneer
Riverstone Networks (RSTN.PK) has signed agreements with two metropolitan
networking equipment vendors to provide joint solutions, marketing, and sales
referrals as part of Riverstone's Ethernet Edge Alliance Program. The new
members are: ADVA Optical Networking (FSE: ADV), a leading global provider of
metro optical networking solutions, and BTI Photonic Systems Inc., a metro edge
optical systems provider.

Riverstone will team with both companies to offer a pre-tested, joint solution
to service providers and municipal network operators. The BTI agreement
provides for co-marketing and sales references. The ADVA agreement goes a step
further to include a fully tested, certified and interoperable joint solution
with integrated network management. Riverstone will work with each of the two
companies individually, sharing training, technical support, and demonstration
equipment for use at marketing events and in sales engagements.

"We're enthused by the spirit of cooperation and innovation these equipment
vendors bring to the alliance program," said David Ginsburg, Vice President,
Marketing and Product Management, Riverstone Networks.  "Our collaboration with
these and other alliance members will help Service Providers more easily find
and deploy the right solutions for their respective networks."

The combination of Riverstone's MPLS-based Ethernet routers with ADVA's Fiber
Service Platform (FSP) 150 optical Ethernet access portfolio offers service
providers an economically attractive, integrated, and end-to-end solution for
the delivery of scalable and reliable E-Line and E-LAN services.

The Riverstone/BTI solution will utilize BTI's Netstender to more economically
extend, expand and connect Ethernet traffic across large metropolitan areas.
Combining the two vendors' products, service providers can significantly lower
their network transport costs while generating new revenues based on Ethernet
services.

"This alliance, and the industry expertise it represents, brings forth a new
era of metropolitan networking, providing carriers with greater flexibility and
profitability through new Ethernet services," said Glenn Thurston, Vice
President, Marketing, BTI Photonic Systems.

The Ethernet Edge Alliance program is designed to accelerate the rollout of
Ethernet services in the metro.  The program pairs Riverstone's MPLS-based
Ethernet solutions with complementary, best-in-class products and solutions
from around the world to help service providers and municipalities
cost-effectively deliver a multitude of residential and commercial voice, video
and data services.  By working together, the alliance members are able to more
affectively address the individual requirements of their potential carrier
customers wherein everyone, the service providers and the vendors, win.

infrastructure solutions for business and residential communications services.
