DEVICE AND METHOD FOR CHARACTERIZING THE TRANSMISSION PARAMETERS OF A TRANSMISSION LINK FOR HIGH BIT RATE DATA TRANSMISSION

摘要

The present invention relates to the high bit-rate data transfers for determining the transmission link of configured transmission, wherein transmission link includes line module (1) in switching centre, and the subscriber connection line (3) of user's modem (2) is used for line pattern module (1) and modem (2). The switching centre for the line module (1) that the present invention also relates to a kind of for high bit-rate data transfer and modem (2) execute the method for the user of high bit-rate data transfer.
