A multi-service transport apparatus for integrated transport networks is described. The apparatus comprises an electrical matrix, termination function means handling signals incoming at said apparatus input, a plurality of termination function means interfacing different layers, and adaptation function means. The termination function means handling incoming signals are implemented in input/output port devices; the termination function means interfacing different layers and said adaptation function means are implemented in adapter devices. According to the present invention, the matrix performs exclusively the switching of the incoming signals that are already terminated and adapted by said input/output port devices and by said adapter devices and it is transparent with respect to the signal format.
