Verizon Communications Inc. was denied permission from the Federal Communications Commission to charge rivals higher rates for access to its lines in Philadelphia and five other East Coast markets.

The FCC said yesterday that evidence of competition does not satisfy its requirements for granting Verizon's request. The markets it would have affected were Philadelphia, Pittsburgh, New York, Boston, Providence, R.I., and Virginia Beach.

The decision  by the FCC was unanimous, a commission statement said. Verizon’s request had been opposed by such companies as Sprint Nextel Corp. and XO Holdings Inc., which in a statement called the FCC decision “a solid victory for competition.”
