Switching device (SM1) in a communication network for transmission of voice and data signals multiplexed using a plurality of time slots. The switching device of the invention comprises space modules and time modules for providing connections between arbitrary time slots on inputs and outputs according to connection requests determined by a control means C. The switching device includes alternate path means for providing a connection on two arbitrary time slots, in case said control means (AP) cannot establish a regular connection via the time modules and the space modules. In a case where blocking occurs, an alternate path using said alternate path means is thus established. Said alternate path means can comprise anti blocking time modules and external devices. The invention allows to reduce hardware costs or to increase load while providing a virtually non-blocking switching device. |
