Abstract

복수의 으뜸기기를 갖는 디지털 코드리스전화의 경우에 있어서 딸림기기의 대기 동작 중의 제어가 적은 소비전력으로 간단하게 되도록 한다.
으뜸기기(1, 2, 3)와 딸림기기(4, 5, …) 상이에서 디지털 데이터의 송신과 수신을 시간적으로 다르게 하여 통화를 함과 동시에 각각의 으뜸기기(1, 2, 3)와 딸림기기(4, 5, …) 사이에서 통화할 수 있도록 한 디지털 코드리스전화장치에 있어서, 복수의 으뜸기기중 기준이 되는 으뜸기기(1)에서 송신되는 제어 신호를, 다른 으뜸기기(2, 3)로 수신시켜 이 제어신호의 수신타이밍에 동기시켜서 다른 으뜸기기(2,3)에서 제어신호를 송신하도록 하였다.

Description

디지털 코드리스전화장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명 일 실시예에 의한 코드리스전화 시스템 구성도, 제2도는 일 실시예의 의한 딸림기구(子機)의 구성도, 제3도는 일 실시예의 의한 으뜸기기(親機)의 구성도.

Claims (3)

  1. 복수의 으뜸기기와 딸림기기로 형성되고, 상기 으뜸기기와 상기 딸림기기 사이에서 디지털 데이터의 송신과 수신을 시간적으로 다르게 하여 통화를 함과 동시에, 상기 각각의 으뜸기기에 공통의 시스템 호출부호를 설정하여 상기 모든 으뜸기기와 딸림기기 사이에서 통화할 수 있도록 한 디지털 코드리스전화장치에 있어서, 상기 복수의 으뜸기기중 기준이 되는 으뜸기기에서 송신되는 제어신호를 다른 으뜸기기에서 신호를 송신하도록 한 디지털 코드리스전화장치.
  2. 제1항에 있어서, 상기 기준이 되는 으뜸기기에서 송신되는 동기 워드를 다른 으뜸기기에서 수신하여 동기시키도록 한 디지털 코드리스전화장치.
  3. 제1항에 있어서, 상기 기준이 되는 으뜸기기에서 송신되는 제어신호에 의거해서 각 으뜸기기에서 송신되는 제어신호의 딸림기기에서의 수신 타이밍을 제어하도록 한 디지털 코드리스전환장치.
