Abstract

1,199,608. Automatic exchange system. HITACHI Ltd. 30 Oct., 1967 [7 Nov., 1966], No. 49138/67. Heading H4K. In a multi office system in which a central office contains AMA, service observation or malicous call tracing equipment, the identity of a calling subscriber attached to at least one of the offices is transmitted to the central office in terms of his equipment number rather than his directory number. The necessary translators for offices using this facility (which offices may be considered as satellites since they are apparently stripped of all translation equipments) are located in the central office. Signalling is effected on a multifrequency basis. Identification date is only sent in response to a request therefor from central office. Crossbar and/or step-by-step offices may form part of the system. If some offices send identities in the form of a directory number a prefix signal is sent to warn the central office that translation is unnecessary.
