Abstract: A bundler, un-bundler and sequencer for use in controlling and driving opposing sets of logical or physical modems to drive multiple-subscriber lines with multiple communication channels. The sequencer determines subscriber requirements such as maximum and minimum bandwidth and quality of service. The sequencer also determines bandwidth availability and status of multiple subscriber lines from which a bundle may be formed. The bundler couple to the sequencer and implement header or headerless insertion of multiple channels in round robin sequence into the X-DSL frames at data rates which correspond with subscriber requirements. The un-bundler reverses the process of the bundler and passes the appropriate packet data onto the corresponding network.
