13,000 WITHOUT PHONES; DISRUPTION TO SERVICE FORCES REROUTING OF EMERGENCY CALLS.

Phone service for about 13,000 customers was knocked out for about four hours Monday, forcing a rerouting of 911 emergency calls.

At about 10:45 a.m., a circuit problem affected incoming and outgoing voice and data transmissions to customers in western Los Angeles County and possibly parts of eastern Ventura County, said Steve Getzug, a spokesman for Pacific Bell.

The problem shut down all telephone service, including 911 calls, at the Lost Hills/Malibu station of the Los Angeles County Sheriff's Department, said Lt. Jim Glazar.

``Everything was affected,'' Glazar said. ``The entire area lost all telephone service.''

The station's 911 calls were automatically rerouted to another 911 center in Lancaster, Glazar said. There 911 operators typed emergency information into a computer and sent it to the Lost Hills dispatchers, he said.

``It really doesn't create a problem for 911 calls,'' he said.

The station's routine business calls were shut down until the problem was corrected about 2:15 p.m.

Workers at the Domino's pizza in Calabasas opened their doors at 11 a.m. and waited patiently for the phone to ring.

``A half-hour into the shift I realized something was totally wrong,'' said Frank Barragan, the assistant manager.

Usually, 11 a.m. to 1 p.m. is the lunch rush hour for orders, Barragan said. On Monday, only two delivery calls were able get through in that time, compared with more than a dozen on a normal day.
