B: Ericsson Unveils Wide Area Metro Ring DWDM Solution with Industry's First
Optical Layer Protection
RICHARDSON, TEXAS (March 1) BUSINESS WIRE -March 1, 1999--Ericsson Inc.
has announced the industry's first optically protected metro ring DWDM
(Dense Wave Division Multiplexing) solution, ERION(TM) Networker,
equipped with Ericsson's patented FlexingBus. By demonstrating the
functionality of the FlexingBus Feature and combining it with the
market-proven Networker DWDM product, Ericsson is offering a product
that combines the bandwidth expandability of DWDM with the reliability
and efficiency of a protected ring.
With the development of the protected ring concept, Ericsson is
challenging the classical definitions of the metro environment by
stretching the boundaries to what the company has termed wide area
metro (WAM). Traditionally viewed as city wide, the Networker equipped
with FlexingBus, has extended the ring circumference to over 500
kilometers making it possible to connect several smaller metropolitan
cities.
The FlexingBus feature not only offers ring connectivity but also
provides inherent protection in the optical layer, making it possible
to carry ATM and IP directly over DWDM and, therefore, significantly
reducing the total cost of network ownership.
"The need for wider area metro rings is supported by international
standards body published information," said Roselyne Genin, vice
president, Optical Networks, Network Operators Group, Ericsson Inc.
"The distance requirements for U.S. metropolitan rings were described
in detail recently in the ITU-T's draft recommendation G.873, 'Optical
Transport Network Requirements.' Statistics from this document predict
that 'the mean circumference of metro DWDM rings will be 150
kilometers.' Additionally, it predicts that 75 percent of those rings
will be greater than 100 kilometers. The Networker equipped with
FlexingBus is the only product on the market today that can extend to
these distances to connect several metropolitan areas."
In addition to employing the only commercially available optical layer
protection, ERION Networker has been optimized to meet the needs of the
emerging metro and WAM markets with an open architecture, manageability
and the most scalable DWDM platform.
"The release of FlexingBus solidifies our efforts to tackle the key
issues involved in deploying effective metro DWDM solutions," Genin
said. "Metro networks need much more flexibility than static, long-haul
routes. The landscape is shifting dramatically as new operators face
the challenges of rapid expansion in data traffic due to growth of the
Internet, e-commerce and increasing global communications. ERION, with
its ability to scale from the local to the wide area, allows operators
to build the networks that can accommodate the demands of tomorrow."
