Abstract
A service that provides a virtual private line between a local exchange and another interexchange carrier. To provide the virtual private line, a switch in a first interexchange carrier receives a code representative of the carrier of choice. The switch identifies the second interexchange carrier from the code, and identifies a location of a point of interface between the first and second interexchange carriers. The switch establishes a call path from itself to the second interexchange carrier through the point of interface.
