BROAD-BAND COMMUNICATION SYSTEM

摘要

1. A broad-band communications system with subscriber connection lines which each extend between an exchange (VSt) and a subscriber station (TlnSt) and which each comprise one single light waveguide (L) for wide-band signals and comparatively narrow-band digital communications signals, in particular 64-kbits/s-digital signals, characterised in that the single light waveguide (L) which forms the subscriber connection line transmits, in time separation transmission mode, only digital communications narrow band signals and bidirectional picture communications digital signals of both directions of transmission between the exchange (VSt) and the subscriber station (TinSt) and vice versa.
