  • Digital switching exchange for telephone systems
    Patent number: 4535444
    Abstract: A digitally operating telephone exchange or central office comprises at least one elemental switching assembly AC including a multiplicity of routing modules MII interconnected by PCM lines FII, each module communicating directly with one or more interfaces UAA, TNN, UGG which provide some of these modules with access to subscriber lines, other of these modules with access to digital trunks extending to remote exchanges, and still other modules with access to analog-type trunks. The operations of the routing modules MII and the digital-trunk interfaces TNN are controlled by a common supervisory processor SGS and are timed by a central clock CKC. A centralized oscillator GC supplies the line interfaces UAA with ringing current and with an audio-frequency carrier modulable for signalization purposes.
