  • Patent number: 4839888
    Abstract: Telephone subscriber connection system based on a ditital time-division switch. System of connecting telephone subscribers whose devices (2) are connected to junctors (6, 7) of a digital time-division switch (1) controlled by a central processor (5). Each junctor is identically connected to the switching network (4) of the switch by the same number of channels of a shared time-division multiplex link (LM0), all information concerning a junctor passing on these channels between the junctor and either another junctor or the central processor. The latter has direct access to the switching memory (17) of the switching network enabling it to read or write there directly. Requests addressed to the central processor (5) from the devices (2) connected to a junctor (6) are directly transmitted by this means to said central processor.
