Abstract: A method for efficient connection between a telecommunications network and a Customer Premises Equipment (CPE) via an access node includes: establishing a physical communication channel between the access node of the telecommunications network and the CPE; providing, by the telecommunications network, a public or private Internet Protocol address to the CPE for use by the CPE to communicate with an Internet Protocol Edge node of the telecommunications network; initially assigning, by the telecommunications network, a first functionality level to the public or private Internet Protocol address; and assigning, by the telecommunications network, a second functionality level to the public or private Internet Protocol address when the telecommunications network is able to federate the network access related identification information to a contract related identification information.

Abstract: A process is described for the preparation of finely divided polymer powders by polymerizing water-soluble monomers in the aqueous phase of a water-in-oil emulsion in the presence of water-in-oil emulsifiers and polymerization initiators, removing the water from the resultant water-in-oil polymer suspension by azeotropic distillation, and isolating the suspended, finely divided polymer powder, either the polymerization of the water-soluble monomers being carried out in the presence of from 0.1 to 10% by weight, based on the monomers employed in the polymerization, of protective colloids, or the protective colloids being added to the water-in-oil polymer suspension after the polymerization is complete. The polymerization is preferably carried out in the presence of surfactant. The finely divided pulverulent polymers are used as flocculants or thickeners for aqueous systems.
