Abstract
Abstract An apparatus for establishing a data communication link with a plurality of other modems on telephone line is disclosed. The Frequency-Division Multiplexing (FDM) compliant modem of the present invention for establishing a data communication link with a plurality of other FDM compliant modems on a telephone line comprises a means for transmitting data on a first modulation band on the telephone line and a means for receiving data on a plurality of distinct modulation bands on the telephone line. The present invention also includes a system for linking a plurality of FDM compliant modems in a multiple site configuration on a telephone line, the system comprising a plurality of FDM compliant modems, each modem of the plurality of modems transmitting data on a distinct modulation band and receiving data on at least two other modulation bands.
