The CPUC’s decision 95-07-054 enables various telecommunications companies to compete with local telephone companies in providing local exchange service. Previous to this decision, local telephone service was monopolized by a single utility per service territory. CPUC received 66 petitions from companies to provide competitive local telephone service throughout areas formerly served by Pacific Bell and GTE California. The 66 petitioners include cable television companies, cellular (wireless) companies, long-distance service providers, local telephone service providers, and various other telecommunication companies that specialize in transporting data. 40 of the 66 petitions are for approval of facilities-based services, which means that the petitioners propose to use their own facilities in providing local telephone service. However, the 40 facilities-based petitions may require both physical modifications to existing facilities and construction of new facilities. Physical modifications to existing facilities may include switch installation, which connects potential customers to outside systems. Other modifications may include installation of fiber optic cables, which would be installed within existing utility underground conduits or ducts or attached to utility poles with existing overhead lines. Depending on the type of technology and facilities operated by the petitioner, small service boxes (approximately 3 inches in height) would be used for power supply and backup power. Those petitioners who have no plans to use such boxes already have capable power and backup power within their existing facilities. The few petitioners who will need such boxes have committed to placing the boxes in existing buildings or in underground vaults. If conditions do no permit building or underground installation, the petitioners would use small low-profile boxes that are landscaped and fenced.
