Packet transmission system

摘要

The transmission system includes a coupling device with a central memory for temporary storage of the information packets receiving from the incoming lines. A central memory control (20) generates the memory addresses for storage of the information packets and controls the write-in and read-out procedures and a demultiplexer, for transferring the data packets to the outgoing lines. The central memory control has an address memory (45), delivering the write-in addresses, the addresses received from the memory held in respective waiting buffers (42,..44) for each outgoing line, selected in dependence on the packet location, with corresponding control of the demultiplexer.
