ABSTRACT:
The invention relates to a packet switching system comprising at least a coupling device which comprises a main memory for buffering packets arriving by auxiliary lines, a main memory controller for generating addresses for the packets to be stored in the main memory and for controlling the write and read operations of the packets and a demulfiplexer controlled by the main memory controller for transporting the packets by trunk lines. The main memory controller comprises an address memory for producing an address for a write operation, buffers assigned to each trunk line, for buffering the addresses produced by the address memory, and a decoding device. The decoding device is provided for selecting a buffer for an address to be stored in dependence on the destination of the packet, for selecting a buffer for producing an address for the read operation from the main memory and for accordingly controlling the demultiplexer.
