Abstract

Information is transmitted between a multiplicity of subscribers as components of traffic in an integrated services network, (ISN), in which the information traffic consists of a multiplicity of media types according to the different subscribers including voice, video, and data traffic component types. The traffic component types in the form of portions of respective information streams to be transmitted from subscribers at an entry point of the ISN are assembled into the payload of each of a sequence of composite frames for transmission through the ISN. The traffic component types subjected to such assembly are limited to those destined for subscribers at the same exit point of the ISN. Traffic component types within the composite frame payload are grouped in sets of adjacent channels of fixed bandwidth so that each group is limited to channels containing traffic components of the same type, with each channel assigned in its entirety to a selected subscriber. Any unused bandwidth is compressed out of the composite frame payload before the frame is launched into the ISN, by eliminating channels assigned to then-inactive or only partially active subscribers.
