Abstract

The present invention relates to the field of high speed data transfer for digital communications using communications networks having relatively narrow bandwidth time division multiplexed channels. The invention also relates to wideband communications using a plurality of time division multiplex channels having bandwidths which are individually insufficiently large to individually support the wideband communications. The apparatus for data communication includes a first interface arrangement for interfacing with a data communications network; a second interface arrangement for interfacing with a data source; and a data multiplexing arrangement for multiplexing data from the data source into a selected number of channels.
