Abstract: Examples relate to detecting potential grey market activities. The examples disclosed herein enable storing, in a product database, a plurality of product identifiers. At least one of the plurality of product identifiers may be associated with a promotion that is intended for at least one end customer. The examples disclosed herein enable triggering a detection of a potential grey market activity in response to receiving customer registration information from a first end customer. The customer registration information may comprise a first product identifier. The detection of the potential grey market activity comprises identifying the first product identifier in the product database and the promotion associated with the first product identifier, and determining whether the first end customer is the end customer for which the promotion associated with the first product identifier is intended.

Abstract: A plurality of elements of a system, such as a telecommunications network are controlled by generating a generic instruction, in a generator selecting the element for which the instruction is directed, in a matcher and interface module and transmitting the instruction to the respective elements. By transmitting a generic instruction applicable to all relevant elements the operator of the system can control all the elements with a single instruction. A generic instruction can be translated in translators into separate instructions applicable to each individual element or defined groups of elements.
