Abstract
Abstract A method and system of transmitting information between a multiplicity of subscribers as components of traffic in an integrated services network (ISN). The information traffic consists of a multiplicity of media types according to the different subscribers including voice, video and data traffic component types. Each traffic component type has attributes of transmission through the ISN which may differ from transmission attributes of the other traffic component types, and the ISN also has attributes of transmission which may differ for transmission of the various traffic component types therethrough. A plurality of the traffic component types to be transmitted, limited to those destined for subscribers at the same exit point of the ISN, is assembled from subscribers at an entry point of the ISN into a single composite frame of variable size for transmission through the ISN. The traffic component types within the single composite frame are grouped into separate groups of adjacent channels for each traffic component type, 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.

Claim 1
Independent Claim
161 words
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 the steps of: assembling a plurality of said traffic component types to be transmitted from subscribers at an entry point of said ISN into a single composite frame of variable size for transmission through the ISN, limiting the traffic component types assembled into said single composite frame to those destined for subscribers at the same exit point of the ISN, and grouping the traffic component types within said single composite frame into separate groups of adjacent channels for each traffic component type, 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.
Claim 2
Independent Claim
161 words
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 the steps of: assembling a plurality of said traffic component types to be transmitted from subscribers at an entry point of said ISN into a single composite frame of variable size for transmission through the ISN, limiting the traffic component types assembled into said single composite frame to those destined for subscribers at the same exit point of the ISN, and grouping the traffic component types within said single composite frame into separate groups of adjacent channels for each traffic component type, 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.
Claim 3
Dependent Claim
35 words
The method of claim 1, further including: launching a succession of the composite data frames from said ISN entry point through the ISN according to the transmission requirements of the subscribers at said entry point.
Claim 4
Dependent Claim
36 words
The method of claim 2, wherein said channels in each composite frame are preset to be of much smaller size than the size of the overall payload containing the traffic component types in the composite frame.
Claim 5
Dependent Claim
31 words
The method of claim 1, wherein the channels in each group of channels allocated to a traffic component type within the composite frame are designated to be of the same size.
Claim 6
Dependent Claim
42 words
The method of claim 3, wherein each of the channels in a group allocated to one of said traffic component types in each composite frame is designated to be of the same size as each of the other channels in that group.
Claim 7
Dependent Claim
46 words
The method of claim 5, wherein the designation of the same size for each of the channels in a group allocated to one of said traffic component types is made consistent for that traffic component type for all composite frames to be transmitted throughout said ISN.
