Abstract: PURPOSE: A call connection method between an IGU(Internet Gateway Unit) PSTN/ISDN and an ISP(Internet Service Provider) is provided to execute Internet call connection after separating the Internet traffic generated from subscribers according to called numbers and linking it with an ISP. CONSTITUTION: If a subscriber clicks on 014XY or 014 through the telephone connection window outputted on a PC connected with a PSTN(A), a hook-off signal is transmitted to an IGU through the PSTN(A)(201). The IGU, recognizing the hook-off signal, provides a suitable dial tone to the PC(202). Then the IGU analyzes the telephone number received from the PC and sets up the path to a PMPM(PSTN Modem Pool Module) if the number is a call access number to Internet(203). The PMPM, in response to the path setup of the IGU, sends a confirmation signal to inform the PC that the path between the IGU and the PMPM has been set up(204). Then the PMPM requests the IGU to set up the path between the PC and a DAC(Digital Analog Converter)(205). The IGU sets up the between the PC and the DAC according to the PMPM's request(206). If the path between to the PC and DAC is set up, the DAC provides an initial screen to the PC through the path(207). The subscriber inputs a digit to select a desired ISP on the initial screen(208). The DAC, receiving the digit, requests the PC to input a login and a password(209). Then the DAC judges whether the subscriber is suitable for accessing the ISP(210). If the subscriber is suitable for accessing the ISP, the DAC allocates an IP address to him(212). If the IP address is allocated, the IGU accesses the ISP through a PSDN(C) and controls the execution of an Internet call service(215).

Abstract: PURPOSE: A method of monitoring the operation of a system for feeding an abrasive medium using fluid as conveying medium for at least one burner in a fusion vaporizer plant is provided. CONSTITUTION: The dust extracted from a fusion vaporizer plant or reduction shaft furnace is to be introduced by means of a fluid and via a dust-conveyer tube(3) through at least one dust burner into the fusion vaporizer plant as an additional carbon-carrier. The method can also be applied in other melting or incineration plants, such as for example fluid bed reactors. To determine as rapidly as possible whether hot gases or unburned oxygen have/has flowed back into the dust-recycling system, the flow direction in the feed system conveying pipe is measured downstream of the burner or burners. When back flow of the fluid flow is determined or when the presence of oxygen which has penetrated the feed system is determined, the feed system is stopped.
