The invention relates to a method and device for managing at least one capability characteristic, which is subject to license or for managing at least one group of capability characteristics, which are subject to license, of a switching system of a telecommunications network. Global optimization techniques, for example, simulated annealing, are used to identify an optimal or near-optimal set of column widths whereby the width of columns having cells containing greater amounts of text are increased while the width of columns having cells containing smaller amounts of text are correspondingly decreased, thus reducing overall table height without changing net table width. The web server module also, in response to control information received through the network interface from the client over the network in response to the sent working status information, controls the working status by sending a control signal to the projection display module based on the control information.
