South Central Bell
South Central Bell Telephone Company, headquartered in Birmingham, Alabama, was the name of the Bell System's operations in Alabama, Kentucky, Louisiana, Mississippi, and Tennessee. South Central Bell was created in  July 1968 when the Bell telephone operations in those states were split off from Southern Bell. South Central Bell was headquartered in (what is now) the AT&T City Center building in Birmingham. In 1984, South Central Bell became a subsidiary of BellSouth Corporation, effectively reuniting South Central Bell with Southern Bell. The two companies were officially reunited in 1992 when Southern Bell absorbed South Central Bell as BellSouth Telecommunications. The two names were used, however, until 1995. See also
