Filed: 1966-01-21
Abstract: 1,139,648. Telephone exchanger. NIPPON ELECTRIC CO. Ltd. 21 Jan., 1966 [21 Jan., 1965], No. 2804/66. Heading H4K. Inter-exchange trunks, between manual positions in a network of exchanges, are tested on command from a main exchange in the network. Each exchange has test equipment which on instruction from the main exchange can effect connection to a trunk. To test a group of trunks the main exchange instructs the test equipment in the exchanges connected by the group so that by acting in concert at each exchange the trunks are connected one-by-one for tests of continuity and transmission quality. The results of each test are sent to the main exchange where they are recorded. Where the working is entirely manual the main exchange uses one of the trunks between manual positions as a link to each other exchange for the purpose of sending and receiving test instructions and data. Where the working between exchanges includes automatic switching the main exchange can gain access to the test equipment at other exchanges by setting up connections over the automatic system as and when required.
