Officials with Tbaytel say a problem with long distance dialing has now been repaired.
At about 2:30 p.m. Monday, crews cleaning up a train derailment near Sudbury accidentally cut an underground cable.
That mishap affected most long distance calls by Tbaytel customers.
The cable was temporarily repaired at about 4 a.m. Tuesday, and Tbaytel officials say the permanent fix should have been completed by the end of Tuesday.
