OCC (Other Common Carrier)

The term applied in the United States prior to the breakup of the

Bell System (January 1, 1984) to describe the long-distance carriers that competed with AT&T Long Lines.As a result of the Modified Final Judgement (MFJ) that caused the reorganization of the Bell System, AT&T and the OCCs became known as interexchange carriers (IXCs, or IECs) and initially were not allowed to provide intraLATA long distance service. See also Bell System, IXC, LATA, long distance, and MFJ.
