Abstract
A System including device access, network access system management, and related method for providing users who have require aperiodic high bandwidth data transmission requirements between remote sites access over a public switched digital network of a conventional type is disclosed. The invention uses a scheme of inverse multiplexing by which it first logically splits a high bandwidth information stream into multiple narrow band signals for transmission through public switched digital network over a plurality of narrow band channels to be received at the remote location by another Switched Network Access System then recombined to form the original high bandwidth information stream causing the multiple narrow band channels to appear as a single high bandwidth channel to remote high bandwidth end users. The Switched Network Access System provides automatic bandwidth allocation and agility which optimizes throughput and reduces data communications costs by adding or dropping narrow band channels "as needed" based on user bandwidth utilization.
