The state agency also urged AT&T to upgrade copper facilities to fiber instead of trying to shut down the outdated portions of its network.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.
