Abstract

1,252,325. Digital transmission systems. SIEMENS A.G., TEKADE FELTEN UND GUILLEAUME G.m.b.H. STANDARDELEKTRIK-LORENZ A.G. and TELEFONBAU UND NORMALZEIT G.m.b.H. 3 April, 1969 [9 April, 1968], No. 17506/69. Heading H4P. Digital data is transmitted in D.C. form from a subscriber to a first automatic exchange wherein it is converted to A.C. form. The A.C. data is passed, via intermediate exchanges if necessary, to a final exchange in which it is converted back to D.C. form and passed to the other subscriber. The number of converters at an exchange is less than the number of associated subscribers, and a converter is alotted to a subscriber only for the duration of the connection.
