A metal halide discharge lamp comprises a lamp body and a chamber formed within the body. The encoded configuration data are loaded into the logic circuit and, by means of the algorithm and a key, which is supplied to the logic circuit logic-circuit-externally and separately from the encoded configuration data and from the un-encoded configuration data, decoded for the activation of the algorithm and stored logic-circuit-internally. The limited number of resources are allocated according to requests from the child nodes in the resource allocation phase.
