Abstract: In one configuration, the present invention is directed to an enterprise network that includes geographically dislocated first and second network regions communicating with one another through first and second networks and respectively comprising first and second gateways and first and second groupings of trunks. A media server is positioned in the first network region that includes a routing agent. When a WAN outage occurs, the routing agent, using a dial plan, maps the dialed digits to an electronic address addressable over the PSTN and routes the call over the PSTN to the destination second communication device in the second network region.

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.

Abstract: The present invention relates to highly branched and coupled polymers based on conjugated dienes or on conjugated dienes and vinylaromatic compounds and on polyfunctional, organic compounds with at least four groups which are capable of coupling. Vulcanization products and shaped rubber articles of all types, in particular tires having an improved rolling resistance, can be produced from the highly branched diene polymers according to the present invention.

Abstract: The present invention relates to polymers which are modified by functional end groups and are based on conjugated dienes or on conjugated dienes and vinylaromatic compounds, a process for their preparation and their use for the production of rubber shaped articles of all types, in particular for the production of tires and tire components, such as tire treads.

Abstract: The present invention relates to polymers that are modified along the polymer chain and are based on conjugated dienes or conjugated dienes and vinyl-aromatic compounds having a content of vinyl-aromatic compounds of up to 60 wt. %, a content of cis-position double bonds of ≧92%, a mean molecular weight of 50,000 to 1,500,000 g/mole and a gel content of ≦5%. The polymers according to the invention can be used for the production of all types of molded articles, wherein in particular their technical and physical properties are improved compared with the prior art.

Abstract: The invention provides modifiers for the anionic polymerization of conjugated dienes or of conjugated dienes with vinylaromatic compounds, wherein the modifiers are specific aminoethers.

Abstract: The present invention relates to filled rubber mixes made from polyether/diolefin rubbers. The rubber mixes according to the present invention are suitable for the production of highly reinforced, abrasion-resistant moldings, in particular for the production of tires which exhibit low rolling resistance and elevated wet skid resistance.
