The procedure for verification of a subscriber line connected to a digital exchange includes use of a computer application program (4) which control a first electronic board (1). The card emits an identification signal applicable to the connected subscriber line, before a digital multiplexer (6), towards a second electronic card (7). The second electronic card is loaded as the line commutator (9,10, or 11) for the subscriber (12,13 or 14) on the test line (8). This allows connection of the subscriber (12,13 or 14) to a line which is compatible with a test robot (2).
