Title: Fault location circuit for telecommunications equipment - has use-incidence counter and time-lapse comparators
Inventor: SCHOENBERGER KARL WILHELM
IPC: H04M3/36
Filed: 1979-07-02
Abstract: Using fewer storage registers per switched line has the drawback that it cannot locate defect equipment items which normally are only for short transitional periods in circuit as for example, trunk selector switches. This drawback is overcome by providing a defect detector unit which stores the statistically lowest number of transactions per hour for each of the trunk selector units which form part of the selection storage and switch assembly, and which obtains from a use-incidence counter the actual number of transactions per hour for each of theswitch elements, and which further contains a comparator circuit for determining whether the actual counts are substantially below the statistical lower limit of normal counts or not. A defect signal is generated when lower. The criterion for switch elements may be a time lapse comparison count.
