The invention relates to an asynchronous transfer mode method of transmitting digital signals in which terminals ( 16, 18 ) send to the same station ( 20 ). Calls are transmitted by cells ( 40, 42, 44, 46 ), the terminals send successively in separate periods ( 60, 62, 64, 66; 70, 72, 74 ), and each cell is assigned at least two orthogonal codes (C 1 , C 2 , C 3 , C 4 ). In accordance with the invention, the duration of the period during which each terminal sends and/or the number of codes assigned to each terminal and/or the number of symbols assigned to a particular code in a terminal can be selected on each sending as a function of a particular power level ( 80 ). |
