A switching device for telecommunication networks, which comprises I/O ports, arranged by groups in I/O cards, for inputting incoming data streams and outputting outgoing data streams of arbitrary protocols, a switching fabric SF for handling internal data streams, a number of adaptation functional blocks AFBs associated with the switching fabric SF and forming a common pool of AFBs. The switching device also comprises a distribution block DB for switching between the I/O ports and the adaptation functional blocks AFBs, and configurable to provide a required connection between any of the I/O ports positioned on any of the I/O cards, and any of the adaptation functional blocks AFBs from the common pool of AFBs.
