- Local telephone service
Local telephone service is the provision of
telecommunications network s and services within a limited geographic region.Traditionally, local telephone service was provided by small companies based in given cities and towns as opposed to larger, national or
international companies.Telephone call s outside of the local area provided for by these companies were patched throughlong distance networks that were, until de-regulation, operation mainly byAT&T . Some providers of local services wereregional Bell operating companies , but not all local telephone companies were aregional Bell operating company or tied to one at the local level, especially after de-regulation of 1996. After de-regulation, these regional Bell operating companies became known asLocal access and transport area s but mainly kept providing the same technical services despite being under a different type of corporate structure.Many communities in the
United States had local telephone companies and in rural areas, up until around the early 1980s (perhaps later in some cases)party line s were commonplace. The local telephone company was responsible for providing equipment alongside services to their customers in most cases although over time, as technology changed, so did the nature of the technical services thus provided. At one time—again mainly in more rural locations—telephones were leased from the local phone company rather than sold outright to customers. Many customers in rural regions hadrotary telephone s that were leased prior to the 1980s. Rural customers in some instances ended up paying tenfold the value of their phones as they leased them for decades—though the lease system was not set up to encourage this situation. More recently, local telephone companies would provide PBX ("Private Branch Exchange") services for small local businesses that needed these switchboard and internal telecommunications services. Local telephone companies have also become very involved in many cases in the provision ofInternet DSL anddial-up services.Local telephone wires terminate at the central office (
telephone exchange ), a structure containing the hardware needed to switch calls among local lines and long distance networks. Thus, when a call was placed by a customer outside the local calling area, the central office would switch the call to the respective long distance network. As technlogy advanced, central offices offered more services and their technical abilities improved. Services such asCaller ID , call return call-waiting,three-way calling , and voice-mail were first offered via central office-based technology although later PBXs also provided them. The role of the local phone company includes serving a given community and interfacing with the large long distance carriers. Prior to the advent ofcell phone s, most phone calls were made vialandline s and local companies were thereby involved in some capacity in this communication.Deregulation and the culture of cell phones has reduced the need in some ways for local telephone services whileDigital subscriber line Internet service and other serivices give local companies new roles in the telecommunications industry.External links
