Abstract
1,176,006. Party line systems. SIEMENS A.G. 9 March, 1967 [10 March, 1966], No. 11221/67. Heading H4K. In originating calls, X and Y parties sharing a single line circuit are identified at the exchange by taking the identity of the calling line circuit (which identity is the same as that of the X party) and by detecting which leg of the party line is earthed; in termination of calls the number of the X party giving direct access to the line circuit but the Y party number being converted to the associated X party number to obtain the line circuit and battery feed to the party line being reversed. If X parties are given even hundreds digits and the associated Y parties are given the next higher odd hundreds digits, the identity of a Y party is obtained from the identity of a line circuit by a simple translation field (Fig. 2, not shown) in which one-out-of-ten inputs are normally transmitted unchanged unless a Y party is concerned when the even inputs are switched to the next higher outputs. To identify a Y party number during call termination the Y parties are given characteristic thousands digits and a translator is provided (Fig. 3, not shown) which normally passes the one-out-of-ten hundreds marks unchanged unless the thousands and hundreds digit indicates a Y party when the translator switches the active odd inlet to the next lower odd outlet to obtain the corresponding X party digit and, consequently, the identity of the wanted line circuit. The occurrence of a translation produces a signal to reverse battery feed to the wanted line. The exchange uses separate originating and terminating registers and the translations are made in a common control circuit which includes a marker. When a calling party identity is fully established it is examined for priority before an outgoing call is permitted.
