<p>Method for access control to the transmission medium of a distributed multiservice switching network able to switch traffic into synchronous circuit mode and into synchronous or asynchronous packet mode, said network being architectured around a transmission medium shared over time between various stations, characterised in that:
- the transmission medium is synchronous and structured into repetitive frames, themselves structured into timing intervals themselves structured into time-cells, the latter being dimensioned to contain a communication entity which may be, as appropriate, a cell in circuit mode or a cell in segmented packet mode,
- an ideal time interval for access to the transmission medium in packet mode is assigned respectively to the various stations communicating inside this network,
- with each time-cell and for all the stations, there is undertaken an arbitration of access to the transmission medium, so as to ensure priority access to this medium by cells in circuit mode which are available at this instant in every station.
