WASHINGTON (AP) _ A software glitch in MCI Communications Corp.’s network disrupted service primarily along the East Coast for about two hours on Thursday before being corrected, said MCI spokesman Kevin Inda.

The glitch affected 16 switches, which are used to route calls. All of those switches are located on the East Coast, except for one in Dallas, Inda said.

″It only affected a slight portion of the traffic on the 16 switches,″ he said. The number of calls affected by the glitch was unavailable.

The problem was detected at 4 p.m. and fixed by 5:26 p.m., Inda said. ″It was a minor outage over a large geographic area,″ he said.
