device and saett foer to link data by a digital vaeljare

摘要

The present invention relates to a method and apparatus for through-connecting data information in a digital selector. It is known to use selector memory devices in digital selectors for the purpose of through-connecting data information. When using selector memory devices in accordance with present day techniques, for instance in selectors of the T-S-type (Time-Space), a large number of selector memory devices are required, which results in problems relating to space and effect. The problem is solved by means of the inventive method and arrangement, since one single selector memory device according to the invention replaces several selector memory devices of known kind. According to the inventive method, data information enters a selector memory device distributed on time slots. Data information is written into the selector memory device during one write phase for each time slot. The data information written into the selector memory device is read therefrom during read phases belonging to the time slots, wherein for read-out purposes two or more read phases are arranged for each write phase. Read-out is controlled for each read phase by a separate control memory device.
