Abstract: A method for operating a telephone system with at least two telephony terminals to where, in addition to voice data or user data, functional data is transmitted by means of special functions of the telephone system, such as forwarding or holding established call connections. It shall be possible in a simple way for the user to handle even a relatively large multitude of special functions. For this purpose, according to the invention, an action key of a first telephony terminal, provided for triggering special functions is assigned the respective special function to be triggered, depending on its own status or the status of a second telephony terminal within the same team.

Abstract: Spherical particles comprising magnesium alcoholate and having a poured cone height of less than 17 mm are prepared by reacting magnesium, an alcohol or a mixture of various alcohols and a halogen and/or an optionally organic halogen compound with one another at below the boiling point of the alcohols. The spherical particles are employed as a precursor for olefin polymerization catalysts.
