Abstract
A time switch and a method for implementing time switching for signals of several different levels of hierarchy. The signals having a common frame structure which can be divided into blocks of different sizes, the blocks being switched differently from one another. According to the method, the contents of the time slots of an incoming signal are written into a memory, from which they are read at the memory locations indicated by switching data contained in an address control memory. In order that the time switching can be implemented in a more simplified manner than before, the contents of all time slots of a frame are continuously written into one memory block without synchronizing the writing with the frame.
