The California Public Utilities Commission (CPUC) yesterday rejected AT&T's request to end its landline phone obligations. The state agency also urged AT&T to upgrade copper facilities to fiber instead of trying to shut down the outdated portions of its network.

AT&T asked the state to eliminate its Carrier of Last Resort (COLR) obligation, which requires it to provide landline telephone service to any potential customer in its service territory. A CPUC administrative law judge recommended rejection of the application last month, and the commission voted to dismiss AT&T's application with prejudice on Thursday.

"Our vote to dismiss AT&T's application made clear that we will protect customer access to basic telephone service... Our rules were designed to provide that assurance, and AT&T's application did not follow our rules," Commissioner John Reynolds said in a CPUC announcement.
