Hawaiian Telcom restored service by midmorning yesterday to about 800 of 1,100 customers in Waipahu whose telephone lines went dead Sunday after two large-diameter telephone cables were deliberately severed in multiple locations along Waipahu Depot Road.

Company spokeswoman Ann Nishida said Hawaiian Telcom repair crews have been working around the clock to restore service since the incident was reported.

"Approximately 3,600 wires in the cables were cut," Nishida said. "Each of those wires has to be identified, repaired and tested. It's a very complex repair procedure."

Anyone with information about the incident is asked to call police.
