A data exchange system of the dial-operated type having a central store to contain the operating relationships between the feeders and trunks of the system, and in which exchange functions are effected through special storage operations of the central store. The special storage operations are caused to be carried out between the read-out and write-in operations of a storage cycle, both to speed up operations and to prevent destruction of stored data by seizure of the system by a priority control unit. |
