Abstract
The present invention relates to a message transmission system which is intended for simultaneously transmitting digital or analog base-band signals, such as ordinary telephone system signals, RNIS or the like, as well as wide-band signals such as ADSL, VDSL or the like.
This transmission is carried out through a dual-wire line extending between a central organ such as a telephone exchange and at least one subscriber. This system comprises at least one base-band unit and one wide-band unit which are connected to the subscriber's line through at least one hybrid circuit and at least one wide-band filter, wherein said filter comprises a high-pass filter and a low-pass filter. The base-band unit, the wide-band unit and optionally the hybrid circuit(s) as well as the wide-band filter(s) are assembled into an unit comprising an interface control central device.
