Abstract A transparent intelligent communication network having nodes and communication links between the nodes and providing improved system input features by including the sampling of customer inputs at different rates according to their output rates of data at the exit node or at faster rates if there is a spare channel capacity available. ## Claims ### Claim 1 A communications network having a plurality of peripheral and central communications nodes, a first plurality of terrestrial communications links connecting said central nodes directly to each other, a second plurality of terrestrial communications links individually connecting said peripheral nodes to said central nodes, means for connecting a plurality of customers to each peripheral node, certain of said means being effective to input data at a first given speed and certain others for inputting data at a different speed, developing means at each of said nodes for successively developing at a first repetition rate multi-user packets each containing data from at least two of said plurality of customers connected to that node, said developing means including means effective in a first mode for sampling data input from said customers at intervals directly related to their output speeds at the exit node and, when in another mode, effective upon the existence of available channel space, at speeds higher than said output speeds at the exit node, and means connected to said peripheral node for conducting said multi-user packets to other nodes within said network. ### Claim 2 (depends on 1) A communications network according to claim 1 in which terrestrial links are further included to link said peripheral nodes in near-neighbour pairs. ### Claim 3 (depends on 1) A communications network according to claim 1 further including a satellite, in which said central nodes are further interconnected directly, each to the other, through said satellite. ### Claim 4 (depends on 1) A communications network according to claim 1, further including a satellite in which terrestrial links are included to link said peripheral nodes in near-neighbour pairs and in which said central nodes are further interconnected directly, each to the other, through said satellite. ### Claim 5 (depends on 4) A communications network according to claim 4, in which at least one of said peripheral nodes is interconnected with said satellite and connected to one central node through a terrestrial link. ### Claim 6 (depends on 1) A communications network according to claim 1, wherein each input node further comprises means effective to produce a plurality of differing electrical signals severally representing destination tables. ### Claim 7 (depends on 1) A communications network according to claim 1 wherein each input node further comprises means effective to produce a plurality of differing electrical signals severally representing activity fields. ### Claim 8 (depends on 5) A communications network according to claim 5 wherein each input node further comprises means effective to produce a plurality of differing electrical signals severally representing activity fields. ### Claim 9 (depends on 8) A communications network according to claim 8 wherein each input node further comprises means effective to produce another plurality of differing electrical signals severally representing destination tables. ### Claim 10 (depends on 9) A communications network according to claim 9 wherein said differing electrical signals representing said activity fields are further effective to cause said developing means to sample said data input from said customers at said intervals directly related to said output speeds of said data at the exit node from said customers. ### Claim 11 (depends on 9) A communications network according to claim 9 wherein said nodes further comprise means for transmitting said differing electrical signals representing said activity fields to successive nodes and to cause said nodes to disassemble multi-user packets received thereat, to reassemble new multi-user packets thereat for further transmission to any succeeding node, and to exit from said node any received multi-user packet mini-packet destined for a customer connected directly to that node. ### Claim 12 (depends on 9) A communication network according to claim 9 wherein said nodes further comprise means responsive to electrical signals severally representing destination tables when received at network nodes to condition said nodes to conduct subsequent customer message information received at said nodes over predetermined paths to predetermined exit ports. ### Claim 13 (depends on 9) A communication network according to claim 9 wherein said nodes further comprise means responsive to differing electrical signals severally representing activity fields to selectively make predetermined changes in said destination tables. ### Claim 14 (depends on 12) A communication network according to claim 12 wherein said nodes further comprise means responsive to differing electrical signals severally representing activity fields to selectively make predetermined changes in said destination tables.
