In a consolidated brief filed in the Eighth U.S. Appeals Court in St. Louis, incumbent local exchange carriers said the U.S. Court should wipe out the Federal Communications Commission`s (FCC`s) entire interconnection order (see "Interconnection delay portends lengthy siege," page 66 and Lightwave, December 1996, page 30). The carriers said the court should do away with the most "unlawful" portions of the order. The brief was filed for GTE, Bell Atlantic, BellSouth, Pacific Telesis, SBC Communications, and US West.
