A multi-service transport apparatus for integrated transport networks that may have 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. 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. The switch may have a time division multiplexing matrix provided with a number of matrix inputs and a number of matrix outputs; source address generators, connected to matrix outputs of the time division multiplexing matrix.

Disclosed is an input port to one or more switching matrices of a network element or the like through a number of backpanel connections, the port receiving input flows in the form of bits arranged in frames, the port comprising: a memory for storing a number of bytes belonging to a tributary; a slicer for slicing the stored bytes in a number of word structures and a backpanel framer for forming backpanel frames with said word structures, the number of said word structures being equal to the number of said switching matrices and the capacity of the input flow being equal to the capacity of the overall backpanel connection capacity.
