A communication network (10,310) having a first broadband communications channel or transmitting bus (12U,312U) and a second broadband communications channel or receiving bus (12D,312D) wherein the first broadband communications channel (12U, 312U) is for passing information upstream to a head end (14, 314) and the second broadband communications channel (12D, 312D) is for passing information downstream from the head end (14, 314) to remote nodes (16, 18, 316, 318). All nodes of the system are coupled to both the first communications channel (12U, 312U) and the second communications channel (12D, 312D).; Modulation of signals applied to the first communcation channel (12U, 312U) is optimized for burst communication from a plurality of sources (16, 18, 316, 318) to central control at the head end (14,314), and modulation applied to the second communications channel (12D, 312D) is optimized for continuous communication from the central source to a target node (16, 18, 316, 318).
