Abstract: The objective of the invention is a method for establishing a subscriber connection and a system applying the method. According to the method, a digital subscriber connection of the FTTC type, consisting of a composition of an optical fiber and a metallic pair cable, is implemented by means of subscriber-specific DSL modems, whereby (a) a subscriber connection comprises an optical fiber (3), a metallic pair cable (6), and equipment (8) adapting the said fiber and cable to each other so that the optical fiber goes towards the telephone exchange or conentrator and the pair cable goes towards the subscriber, and (b) each DSL modem comprises digital transmitter and receiver elements (21,22) connected functionally to analog parts (5) that are adapted to convert (i) the digital output signal of the digital transmitter element (21) into analog form and (ii) the analog signal intended for the receiver element (22) into digital form.
