The New York Public Service Commission (PSC) has approved comprehensive rate and service tariffs enabling AT&T Communications of New York, Inc. (AT&T) and Frontier Communications of Rochester, Inc. (Frontier) to provide local telephone services in the Rochester, NY, service area. The PSC expects to approve a third set of tariffs for Time Warner AxS of Rochester, L.P. early this year. The new tariffs will allow telephone customers in the Rochester area to choose between the three new market entrants and the existing local carrier, Rochester Telephone Corp. The new tariffs come just over two months after the PSC approved its ground-breaking open market plan for Rochester Telephone, which included a seven-year incentive rate plan, a rate cap, and a $21-million rate reduction. The plan split the local carrier into three corporate entities: a holding company (R-HC); a regulated local carrier, R-Net; and a competitive reseller, Frontier.
