The invention concerns a call control method for IP based telephone services and a call control server providing IP based telephone services within a communication network. The call control server assigns two or more IP telephone terminals to a telephone number commonly shared by these IP telephone terminals. It stores IP address data of these IP telephone terminals in the registry of this call control server which is responsible of VoIP calls directed to this telephone number. An IP telephone terminal transmits a presence message to the call control server when a presence button of the IP telephone terminal is pressed. VoIP calls directed to the telephone number are routed to that one of the IP telephone terminals assigned to the telephone number, the call control server has received the presence message from.

In a method for the production of a magnet coil arrangement which can create a predetermined magnet field B and has a minimal inductance L. The magnetic field B to be generated is expanded in spherical harmonics with coefficients C.sub.n,m and a field error .DELTA. B=f.sub.1 (C.sub.n,m) is defined fixing the deviation of the magnet field profile of the coil arrangement to be calculated from the given magnet field B within a volume and, if necessary, further parameters P=f.sub.2 (C.sub.n,m) are predefined, whereby the value of P which is calculated with a particular set of coefficients C.sub.n,m is within predetermined limits. By defining limits for technically relevant parameters and their variation as well as by giving the desired minimum inductance, the procedure achieves a high flexibility in conjunction with independent optimization of the parameters, in particular field errors, minimum inductance and current density oscillations.

摘要:
Disclosed is a process and apparatus for separating aspherical particles from spherical particles in an admixture thereof, preferably in the preparation of a particulate carrier material for two-component developer systems for electrostatic copy devices. The process comprises directing the mixture of particles onto a surface which is inclined with respect to the horizontal; producing a relative velocity between the inclined surface and the mixture of particles, the velocity having a directional component transverse to the steepest inclination gradient of the inclined surface; and collecting a portion of the mixture of particles in a zone of the inclined surface wherein predominantly spherical particles have accummulated as a result of their greater tendency to roll in response to the relative velocity than the aspherical particles.

The invention concerns a method of providing voice and/or multi-media communication over a DSL access network as well as a DSL access multiplexer (21) and at least one integrated access device (32). The DSL access multiplexer (21) and the integrated access device (32) are connected via a subscriber line (42). A voice/multi-media session is established via the DSL access network, wherein data of the voice/multi-media sessions are transported in form of IP packets by using a real time protocol. An AAL2 circuit (72 to 75) is allocated to the voice/multi-media session. The headers of the packets of the voice/multi-media session are compressed and AAL2 circuits (72 to 75) allocated to voice/multi-media sessions are used as underlying tunnel layer. The header compressed packet of the voice/multi-media session are multiplexed into the allocated AAL2 circuits (72 to 75) and the header compressed packets are transported via the allocated AAL2 circuits (72 to 75) between the integrated access device (32) and the DSL access multiplexer (21) through the DSL access network.
