Filed: 1970-01-29
Abstract: 1288161 Automatic exchange systems AUTOMATIC ELECTRIC LABORATORIES Inc 29 Jan 1970 [30 Jan 1969] 4416/70 Heading H4K In an exchange system in which calls can be established over alternative inter-exchange routes and each exchange employs a translator for converting each call directive code into routing information giving a primary route and an alternative route, some translations involve an intermediate translation giving a traffic-plan digit used in the final translation, and provision is made to selectively alter traffic-plan digits to vary the order of route preference for those particular codes. As described each exchange is controlled by a central processor including a magnetic core store in which the program, switching information and translations are stored. A traffic controller having a normal appearance at one of the exchanges can by dialling priority and route digits, a special three digit code specifying an exchange, six digits specifying an intermediate translation in the corresponding core store and an instruction digit can modify the traffic plan digit in that intermediate translation or in a group of such translations. At the originating exchange the class of service of the caller initiating a traffic plan change call is tested and if it is found that the call does not originate from the controllers station or the wrong sequence of digits are dialled the call is routed to an announcement machine. When a traffic plan is correctly effected by the controller he is connected to an announcement machine which specifies the change effected. The format of various words in store and circuitry for processing the instructions is detailed.
