Abstract: PURPOSE: A method for a D-channel packet service in an ISDN(Integrated Services Digital Network) switching system is provided to convert a logical channel of an actual DTE(Data Terminal Equipment) in DTE/DCE(Data Circuit terminating Equipment) interface to a new virtual DCE logical channel in a network to be switched in software through the converting inside the network, when managing logical channels for physical links with multiple logical links. CONSTITUTION: A mapping table for converting logical channels is allocated to processing devices of originating/terminating parties of a network, in order to convert a logical channel of an actual DTE on interface between the DTE and a DCE into a new logical channel of the DCE. If D-channel packet data are generated to an originating subscriber inside the DTE and supplied to the processing device of the originating party, a logical channel of the originating subscriber is converted to the logical channel of the DCE by using the mapping table for converting logical channels. The D-channel packet data replaced by the converted logical channel are transmitted to the processing device of the terminating party. If the processing device of the terminating party receives the D-channel packet data replacing the logical channel, the D-channel packet data are converted to a logical channel of the originating subscriber inside the DTE by using the mapping table for converting logical channels. The D-channel packet data replaced by the converted logical channel are transmitted to the originating subscriber inside the DTE.

Abstract: PURPOSE: A control method of driving force in the turning of an FR(Front-engine Rear-wheel drive) vehicle is provided to prevent an accident caused by overspeed the turning of an FR vehicle by controlling driving force through comparison between a steering angle and vehicle speed in turning of the vehicle. CONSTITUTION: A steering angle of a steering wheel is detected from a corresponding sensor. The RPM(Revolutions Per Minute,Rf,Rr) of front and rear wheels is detected from each RPM sensor. Then, a slip rate(S) and velocity(V) of the rear wheels are calculated from the RPM of the front and rear wheels. If the slip rate is lower than 0, the RPM of the rear wheels is lower than the RPM of the front wheels. Turning of a vehicle is decided by the steering angle. When the vehicle is turned, the velocity of the rear wheels is compared with Vm wherein the Vm is value obtained from a map of an ECU(Electronic Control Unit). The Vm is the optimum velocity for securing safety in turning of a vehicle at the current steering angle. If the velocity is larger than the Vm, the vehicle has danger of escaping a traffic lane. The ECU isolates fuel to a fuel injector to reduce the drive force of the rear wheels. Therefore, the turning velocity of the vehicle is reduced.
