Abstract
An electronic spatial telephonic concentrator is controlled to ensure that a route between a particular subscriber and particular channel is established or disconnected and that a double connection such as between two subscribers has not been made to a third subscriber. A control circuit comprises a subscriber transformer (Ti) with its secondary (5) connected to a voltage generator (6) and to a two stage concentrator (1E,2E). A relay (7) is controlled by control logic (14) from the concentrator. A relay (7) is controlled by control logic (14) from the concentrator. A differential transformer (TD) is connected to a channel (Vj) in the concentrator and is connected to a detector circuit (D) comprising a multiplexer (11) and comparator (12) with a voltage generator (13). A control logic stage (14) checks the comparator output conditions.
