Abstract

1291793 Automatic exchange systems SIEMENS AG 19 April 1971 [19 March 1970] 24834/71 Heading H4K In a sectionalized exchange having a programme controlled processor associated with each section and a further programme controlled processor which exercises over-all control associable via a bus system with all the individual processors, one of the latter is rereserved for data terminals and contains a store, and forward arrangement for use in transmissions between subscribers and data terminals. A data terminal DE may comprise . a digital computer possibly remotely located from the exchange. Whenever such a terminal is involved in a cell, whether as a calling or a called party, a portion of store DS is reserved therefor. The terminal inserts data in or receives data from store in the form of blocks utilizing a parallel transmission mode. The specially reserved processor SS connects the store to suitable data transmission devices Du attached to inlets of the switching network KF in order to permit communication with e.g. subscribers TS, operators PL or other data equipments. (Devices A serve as scan points between the peripherals and the processors). Parity checks may be effected by processor SS as well as by the data terminals. Any or all of the processors may be duplicated for security reasons.
