    Abstract: A switching arrangement for long distance telephone exchange installations with central apparatus having a central control means and individual apparatus, the latter being divided into different groups, each group having a plurality of differently functioning individual apparatus. Individual buffer storage and/or code conversion systems are assigned to each group and is connected thereto over a transmission line of a first type transmitting parallel coded information. Each group is connected over a joint transmission line of a second type having series coded information.

    Abstract: A circuit arrangement for telephone exchange installations wherein messages of different length are divided according to their length into a number of corresponding code signals of constant information volume for transmission in series over the same transmission path and consist of equally large groups of code elements, and wherein, prior to the code signals of a message, a length indicating signal indicative of the length of the message is transmitted to indicate the number of code signals corresponding to the message. First counter means presettable to an initial position by the length indicating signal and controllable to switch forward in pulse manner to a first predetermined position are used in conjunction with second counter means synchronously dependent on the switching forward of the first counter means and responsive thereto to be switched forward out of a second predetermined position. The second counter means have control outputs assigned to its counting positions that control the transmission and reception of code signals transmitted in series over the same transmission path from and to circuits individually assigned thereto. A comparator is responsive to the first counter means when the latter attains the first predetermined position to test the position of the second counter means and the received length indicating signal with regard to agreement.

    Abstract: A central command generator for control commands of timedependent program controlled functional sequences in exchange installations, the command generator having a pulse generator and at least one counting register with individual stages. At least one separate storage segment is assigned to each individual stage. Means are provided to register the identification addresses of the control commands after the expiration of a predetermined time interval or for the counting off of predetermined time intervals, in the corresponding storage segment assigned to that stage of the counting register which follows the stage identified by the counting register, by a number of stages equal to the quotient of the associated time interval and the basic period of the counting register.
