Abstract
A system is disclosed for completing communication connections from end-users served by a connectionless (broadcast) type system in a manner which allows expansion of the calling area beyond the immediate physical limitations of the broadcast media. The system is based upon a device for mediating between the connectionless system and a connection oriented system. The device creates logical local area networks interconnectable by the connection oriented system. Calling user identification is used in conjunction with call completion data stored in a central memory for controlling all interconnections.
