Abstract

본 발명은 디지탈 키폰의 검사 방법에 관한 것으로, 종래에는 디지탈키폰상태의 이상유무를 검사하기 위하여 별도의 장치가 마련되지 않고 제품출하시 인력에 의존하여 검사를 수행함으로서 생산성저하 및 원가가 상승되는 문제점이 있었다. 중앙제어(700) 디지탈 데이타 송수신부(1000), 피씨엠 연결 및 사용자 선호 연결부(900), 톤발생부 및 이득조절부(800)로 구성되는 디지탈 간이교환기(B)와 제어부(100), 송수화부(200), 스피커톤부(300), 아날로그스위칭부(400), 신호변환부 (500), 디지탈 데이타 송수신부(600)로 구성된 디지탈키폰(A)를 포함하는 디지탈키폰의 자기진단 검사방법을 마련하므로서 디지탈키폰 상태의 이상유무를 주장치에 연결된 디지탈키폰으로 검사를 수행할 수 있으므로 생산성향상 및 원가를 절감시킬 수 있는 것이다.The present invention relates to a method for inspecting a digital key phone, conventionally, a problem that the productivity is reduced and the cost is increased by performing a test depending on the manpower at the time of product shipment without a separate device for inspecting the abnormal state of the digital key phone. There was this. Digital control unit (B) and control unit (100), which is composed of the central control (700), digital data transmission / reception unit (1000), PCM connection and user preferred connection unit (900), tone generating unit and gain control unit (800). Self-diagnosis method of a digital key phone including a digital key phone (A) consisting of a receiver 200, a speaker tone unit 300, an analog switching unit 400, a signal converter 500, a digital data transmission and reception unit 600 By providing a digital key phone connected to the main device to check whether there is an abnormality in the state of the digital key phone, productivity and cost can be reduced.

Claims

When the digital simplified exchange system enters the test load, a first step of generating a specific tone for a test and then connecting a user's line and converting the analog tone signal generated in the first step into a digital signal are performed through a data line. A second step of transmitting to the digital key phone system for the connected measurement; a third step of converting the digital signal received in the second step into an analog signal and transmitting the same through the speakerphone; and the tone signal transmitted in the third step. The fourth step of converting the signal fed back through the handset and applied to the digital signal, and then transmitting the signal to the simplified exchange side, and comparing the digital signal received in the fourth step with the normal reference signal to display whether or not through the display means Self-diagnostic test method for a digital keyphone, characterized in that it comprises a fifth step.
