摘要： A constant current controlling part of an LED array driving apparatus includes a PWM IC including an RT/T terminal for outputting a sawtooth wave voltage, a COMP terminal for receiving a comparison voltage to be compared with the sawtooth wave voltage, an output terminal for outputting a pulse signal that is turned off during an interval where the sawtooth wave voltage is higher than the comparison voltage and turned on during an interval where the sawtooth wave voltage is lower than the comparison voltage, and a comparison voltage setter setting the comparison voltage inputted to the COMP terminal. When an overvoltage is applied to the LED array or the LED array is to be turned off by an external dimming control signal, the comparison voltage setter sets the comparison voltage to a value lower than a lower limit of the sawtooth wave voltage.

摘要： The present invention relates to method and apparatus for providing an arbitrary sound chosen by a called subscriber instead of ringback tone to a calling subscriber. In this present invention, if a call is received, a terminating exchanger requests a trunk connection to a sound db server based on the first information on whether or not to replace a ringback tone and the second information on a route to the sound db server that are received from a home location register (HLR), and provides a called subscriber identification for the sound server. Then, the sound db server searches its db for a sound specified by the called, and provides the found sound for the caller instead of a conventional ringback tone via the terminating exchanger connected through a trunk. Through this sequential procedure of network elements, a caller can hear a sound specified by a called instead of a dry ringback tone.
