Abstract

L'invention concerne un procédé pour transmettre des informations codées sous forme binaire. Selon ce procédé, les bits d'informations sont transmis sous la forme de charges positives ou négatives pendant un premier élément de temps dans une ligne bifilaire ZLA affectée de capacités C et reliant deux appareils termineurs de ligne LE, les charges se répartissant entre les capacités au cours d'un second elément de temps tandis que pendant un troisième élément de temps on détermine l'état de charge de la ligne en le comparant à charge impliquée, une décharge des capacités affectant la ligne se produisant au cours d'un quatrième élément de temps dans l'intervalle de temps d'un bit. Application notamment dans des installations de multiplexage temporel PCM.The invention relates to a method for transmitting information encoded in binary form. According to this method, the information bits are transmitted in the form of positive or negative charges during a first time element in a two-wire ZLA line allocated with capacitors C and connecting two line terminating devices LE, the charges being distributed between the capacitors during a second time element while during a third time element the state of charge of the line is determined by comparing it to the charge involved, a discharge of the capacitances affecting the line occurring during a fourth element time in the one-bit time interval. Application in particular in PCM time division multiplexing installations.
