Abstract
Abstract A high bandwidth data loop employs a plurality of individual circuits of a telephone network using a dialing inverse multiplexer communications device. The dialing inverse multiplexer is capable of selectively accessing ones of the plurality of circuits so as to provide any selected bandwidth or bit rate up to the total number of circuits which can be handled by the dialing inverse multiplexer communications device, between any number of locations, for any selected period of time or for any indeterminate period of time.
