<p>IN A COMMUNICATION TERMINAL EQUIPMENT AND A METHOD OF CONTROLLING CALL INCOMING, UNNECESSARY NOISES IN A PERIOD FROM START OF AN ALERT SOUND TO CARRYING OUT OF THE NEXT OPERATION CAN BE REDUCED. WHENA PREDETERMINED OPERATION IS EFFECTED UNDER THE CONDITION THAT AN ALERT SOUND IS RINGING, THE ALERT SOUND IS STOPPED OR THE VOLUME OF THE ALERT SOUND IS REDUCED AT LEAST OVER A DURATION OF CALL INCOMING. THUS, SUCH A FEAR THAT PERSONS IN THE SURROUNDINGS MAY BE TROUBLED BY THE CONTINUOUS RINGING OF THE ALERT SOUND CAN BE REMARKABLY REDUCED. FURTHER, SINCE THE SITUATION THAT POWER SUPPLY IS CUT OFF FORCIBLY DURING CALL ORIGINATION CAN BE AVOIDED, SUCH A FEAR THAT A PERSON ON THE CALL ORIGINATION SIDE MAY BE GIVEN AN UNPLEASANT FEELING CAN BE ELIMINATED.(FIG. 3)</p> |
