Electric Lightwave Inc. of Vancouver, Wash., announced that it would implement what it calls the largest ringed SONET network in the Western US. The company's 3000-mile SONET ring is slated for completion in the fall of 1999. It will consist of a 1300-mile stretch from Portland, Ore., through Sacramento, San Francisco and Los Angeles. A second 1600-mile inland route will connect Los Angeles, Las Vegas, Salt Lake City, Boise, Idaho, and Portland. The network will connect with other broadband long-haul routes between metropolitan areas. Once completed, it will span more than 4500 miles.
