- 25 - METHOD FOR CARRYING OUT LOOPBACK TEST ABSTRACT OF THE DISCLOSURE The present invention discloses a method for carrying out a loopback test in a data communication system, which is comprised of a first data communication station, a second data communication station and a transmission line connected therebetween. The first data communication station transmits a succession of a first pseudo-random noise signals, a loopback test signal and a second pseudo- -random noise signal to the second data communication station by utilizing a usual information data channel, and requires no special channel for carrying out the loopback test. When the second data communication station detects the first pseudo-random noise signal, it sends back the forthcoming loopback test signal to the first data communi- cation station in order to check the coincidence of the transmitted and the sent back loopback test signals. The second pseudo-random noise signal denotes the finsihing of the loopback test.
