Abstract
Abstract A method using an advanced intelligent network to seamlessly connect a plurality of virtual networks includes the steps of: (a) Receiving a number of dialed digits at a first service switching point in a first local access and transport area (10); (b) When the first service switching point is determined to be a hub service switching point (22), sending a query to a service control point (24); (d) Determining if the dialed digits require an access to a private networks interLATA call; and (e) When the dialed digits require access to the private networks interLATA call, routing the call over a tie line (40) to a second hub service switching point (34) in a second local access and transport area (26).
