    摘要: A broadband integrated subscriber loop system is provided in accordance with the teachings of the present invention. A system is provided in which the subscribers are combined in groups (T1n1-T1n10) each of which is supplied via a single optical communication link. Over the optical waveguide (LWL) of this optical communication link, signals of the channels assigned to subscribers for various telecommunication services are transmitted on a multiplexed basis from the switching unit to an interface unit closely located to the subscribers of the group. In the interface unit the channels are separated and subscriber-assigned multiplexers (Mux 5) combine the channels assigned to a subscriber in accordance with the transmission capacity required into a subscriber time-division-multiplex signal. This signal is transmitted over a subscriber line in the form of a coaxial electric line (KL 1) to subscriber's taps, where the signals for terminals located at the top are separated via demultiplexers (Demux 3, Demux 4, Demux 5, Demux 6). Signals to be transmitted from a subscriber's terminals to the switching unit are combined in digital form (Mux 2, Mux 3, Mux 4), and a multiplexer (Mux 1) in the interface unit combines signals from all subscribers of the group into a back-channel multiplex signal which is transmitted to the switching unit over an optical communication link using the same or a second optical waveguide. In the switching unit, a demultiplexer (Demux 1) separates the received signals into the signals from the individual subscribers, and the signals of each subscriber are split up according to the subscriber's various telecommunications services. The system, including the terminals, is fully digital.

    摘要: According to the invention, for connections between terminals connected to different networks, the terminals intended for connection to the network having the higher capacity are so equipped that, alternatively (I, II), they could also operate at the network having the lower capacity. In these terminals as well as at the interface between the two networks, simple network interface devices (30, 60) are inserted which insert and extract the filler bits in a suitable manner.
