A device for initiating multiple timings has a supply of clock pulses. At each clock pulse, an entering cell is stored in a communication system with asynchronous time switching. The stored cell belongs to a virtual communication circuit that carries a number in the label of the cell. A random access, read-write timing memory (MT) has a plurality of addressable zones which normally store null or inactive bits. The memory (MT) is alternately addressed for writing and for reading. The memory (MT) comprises a data input (ED) to store, in a zone addressed for writing, a parameter bound to a characteristic of a virtual circuit. A data output (SD) delivers the content of the memory zone addressed during reading.
