EAU CLAIRE, Wis. - August 17, 2000 - Wisconsin Independent Network* (WIN*), a fiber-based carrier and bandwidth provider in Wisconsin and Minnesota, has selected metropolitan-area fiber optic equipment from Nortel Networks* [NYSE/TSE: NT] to expand its network in southeastern Minnesota and western and central Wisconsin.

WIN, a carrier's carrier, will deploy the Nortel Networks OPTera* Metro Multiservice Platform in a new SONET ring. OPTera Metro is a fiber optic transport system.

"As we continue to grow our network, we have increasingly relied on Nortel Networks to provide winning solutions in fiber optic networking for metropolitan areas," said Scott Hoffmann, Executive Director of WIN. "OPTera Metro is superior to other solutions we examined."

"As a builder of the high-performance Internet, we are committed to providing carriers large and small with optical networking solutions - for global networks, or for regional SONET rings like those WIN is deploying," said Brian McFadden, vice-president, Metro Optical Solutions, Nortel Networks.

WIN currently operates a 600-mile SONET ring in Wisconsin and Minnesota that runs through Minneapolis and the Wisconsin cities of Eau Claire and Superior. With completion of the new SONET ring in the fall of this year - along with a new fiber route to Phillips, Wis. - the WIN network will extend 670 miles from Eau Claire, Wis.; through Rochester and Winona, Minn.; through La Crosse, Wis.; through a number of other Wisconsin communities; through Wisconsin Rapids; to just outside of Wausau, Wis. It will have 24 points of presence (POPs) throughout Wisconsin and Minnesota, with more planned for 2001.

The network will operate initially as an OC-48 SONET network, with plans for future upgrades via Dense Wave Division Multiplexing (DWDM).
