¿µ¹®³»¿ë¿ä¾à | THIS STANDARD DESCRIBES THE TRANSMISSION CHARACTERISTICS AND THEIR MEASURING METHODS FOR ISDN TELEPHONE CONNECTED TO ISDN. THIS STANDARD DEFINES LOUDNESS RATINGS, DISTORTION, IDLE NOISE, OUT-OF-BAND SIGNALS, TERMINAL COUPLING LOSS, STABILITY, AND DELAY WHICH HAVE AN EFFECT ON SPEECH QUALITY OF ISDN TELEPHONE. IN THIS STANDARD, THE EVALUATION METHODS FOR MEASURING THE TRANSMISSION CHARACTERISTICS OF ISDN TELEPHONE ARE ALSO DEFINED. THIS STANDARD IS ENACTED TO ENHANCE THE DOMESTIC TRANSMISSION QUALITY OF END-TO-END DIGITAL NETWORK COMPOSED OF ISDN TELEPHONE AND TO SUPPLY BETTER SPEECH QUALITY FOR USERS. | ||
