For use in a multi-protocol layered transmissions network including a plurality of network elements, a hybrid network element capable of operating at more than two layers, and a method for displaying a model of the multi-protocol layered transmissions network. The method comprises the steps of: determining different and preferably hierarchically related protocol layers in the multi-protocol layered transmissions network; and for each protocol layer, displaying an overlay including the hybrid network elements if operative in the protocol layer, displaying at least one physical link and/or a logical link interconnecting pairs network elements, wherein displaying a logical link so as to show that transport service along the logical link is at least partially provided by a transmission path on a protocol layer underlying the protocol layer. The method preferably comprises displaying a pair of association links between each logical link and its associated transmission path.
