Method for Establishing a Subscriber Connection and a System Utilizing the Method

A system for establishing a digital subscriber connection between a central site and a subscriber's transmission device, the system comprising:

• an optical fiber between the central site and an intermediate equipment, the central site being capable of transmitting a first signal in digital form to the optical fiber and receiving a second signal in digital form from the optical fiber,
• a metallic pair cable between the intermediate equipment and the subscriber's transmission device, the intermediate equipment being capable of receiving the first signal in digital form from the optical fiber, converting the first signal into analog form, transmitting the first signal in analog form to the metallic pair cable, receiving the second signal in analog form from the pair cable, converting the second signal into digital form, and transmitting the second signal in digital form to the optical fiber;
• wherein a digital DSL (Digital Subscriber Line)-modem, is located distributed between the central site and the intermediate equipment such that:
• the intermediate equipment includes a first transmitter part of the DSL-modem for digital signal processing of the first signal,
• the central site includes a second transmitter part of the DSL-modem for digital signal processing of the first signal,
• the intermediate equipment includes a first receiver part of the DSL-modem for digital signal processing of the second signal,
• the central site includes a second receiver part of the DSL-modem for digital signal processing of the second signal, and
• the intermediate equipment includes analog parts of the DSL-modem for analog signal processing of the first signal and for analog signal processing of the second signal.
