Abstract
A device for scanning a large number of scan points that can take two switching states, for example, subscriber lines of a telephone switching system of the central control type, in which the scan points are cyclically scanned to obtain information referring to the switching state, and in which the result of the scan is compared with the scanning result of the previous scan operation, and in which only one control operation is started if the result of the scan is different of the previous scan (called the last result method), characterized in that the result of the scan of a group of scan points forms a code word from which, through a test generator, an information of associated test, because only this test information is retained for the groups of scan points and compared with the test information of the preceding scan cycle, and because in the case of a mismatch of a test information with the associated test information held during the relevant scan cycle, a control operation is performed.
