METHOD FOR IDENTIFICATION OF A DATA TRANSMISSION DEVICE

摘要

In a method for identification of a data transmission device (1, 5) in a data transmission system, a data transmission connection is formed between at least a first (1) and a second data transmission device (5). The identification is conducted two ways, wherein the second data transmission device (5) identifies the first data transmission device (1) and the first data transmission device (1) identifies the second data transmission device (5). The identification comprises at least the following steps: generating at least one identification message (R1, R2), transmission of said identification message (R1, R2) between the data transmission devices (1, 5), generating a check-up message (C1s, C2p) of said identification message (R1, R2) in the receiving data transmission device (1, 5), sending said check-up message (C1s, C2p) to the data transmission device (1, 5) which sent the identification message (R1, R2), in which a verification message (C1p, C2s) is generated, with which the received check-up message (C1s, C2p) is compared.
