1. A method of transmitting information 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 communications services required by the different subscribers, including voice, video and data traffic component types, said method comprising:

  • assembling at successive ones of a predetermined fixed interval of time a plurality of traffic component types in information streams from subscribers associated with an endpoint node of the ISN into composite frames of variable size for sequential launching of the assembled composite frames into the ISN destined to subscribers associated with another endpoint node of the ISN,limiting the traffic component types assembled into each of the composite frames to those in information streams destined for subscribers associated with said another endpoint node of the ISN, at which the composite frames are to be disassembled,configuring each assembled composite frame with the traffic component types assigned to respective separate groups of adjacent channels of bandwidth allocated according to predetermined communication requirements of the particular traffic component type through the ISN, with each group limited to channels of identical fixed size transporting traffic components of the same type and each channel in a group dedicated to a particular subscriber of the respective traffic component type for a communication session, andsynchronously launching the assembled composite frames successively into the ISN at said fixed interval of time as the frame launch interval.
