RALEIGH "MAIN" CENTRAL OFFICE

BELLSOUTH TANDEM and AT&T TOLL OFFICE

The Raleigh "Main" central office serves Bell South as the main regional tandem for the Raleigh metropolitan area and AT&T for long distance and toll services.  The office was originally built by Southern Bell Telephone and Telegraph Company and expanded and modified by BellSouth in the 1980s.  Raleigh became part of the AT&T Direct Distance Dialing Network in August 1971 #4A switching machines.  The Raleigh office was classified as a Primary Center with a direct trunk group to the Charlotte Sectional Center.  Raleigh became an AT&T Long Lines microwave hub when TD-2 microwave service was introduced in the early 1960s.  Microwave paths were initially to the Westover site.  Today the CO has major fiber connections to Charlotte, Durham, Fayetteville, Greensboro, Richmond and Wilson.
