The invention relates to a method in a reporting communications node for detecting usage of a resource within a radio access network. The door has a retractable, multiple pin deadbolt bar that can be operated by an inner or outer door handle. Preferably, the illumination system is provided on poles or on a crash barrier adjacent the traffic lanes 1. A length of a coil end portion can be shortened widely. Thus, a color separation table is generated which corresponds to combinations of six colors Y, M, C, K, Lm, and Lc.
