A circuit arrangement for telecommunications installations, in particular telephone communication installations, with central devices, in particular a central control mechanism, and with individual devices divided into different classes, according to mission, function and/or operation, also provided for repeated according to their class, especially coupling fields with route search and coupling field command devices, with subscriber lines, identifiers, call pulse selectors, connection units for internal and external communications, registers and the like, and with memory and/or transcoding devices common with the individual devices, which serve for the reciprocal adaptation in the transmission of information between the central devices and the individual devices in both directions, and which through transmission lines of a first type, they are linked with the individual devices, while at the transmission lines of a second type can be interconnected with the central apparatuses, characterized in that the individual apparatuses are assembled in closed groups, within which are included in each case some of the individual apparatuses of the different ones, with preference of all the different classes, and because these groups are assigned their own buffer and/or transcoding device, universal with respect to the different classes of individual devices and that, through a transmission line of the first type, is only linked with the individual devices of the corresponding group.
