The device enables the submission of broad band (fast) access to the global computer network (Internet) and can be used for offering services to the subscribers of duplex telephone numbers, as well as for house or business clients connected to telephone lines with carrier telephone type PCM 2/4. The joint signal arriving on the two-wire telephone line a,b TEL + ADSL enters the input of the go round filter (1) where the two signals are separated. From one of the outputs of filter (1) to the duplex box (2) the standard telephone signal TEL is supplied for the separation and connected to the twin-wire lines (a1, b1), or the telephone subscribers (TA1) and (a2, b2), or telephone subscriber (TA2), respectively. The signal for ADSL is transited only to the (a2, b2) line where it is again merged with the telephone signal TEL. By it the perimeter of offering ADSLL-services is considerably increased, thus preventing completely any refusals to offer services due to the lack of technical facilities.
