Abstract

다중화 장치를 이용하지 않고, 전화교환기의 하나의 디지탈 내선 회로에 복수의 디지탈 전화기를 다중 접속시킨 것이다.
즉, 전화교환기(1)에서 제공되는 디지탈회선(4)에 복수의 디지탈 전화기(2A, 2B)를 직접 다중 접속시킨 구성에 있어서, 각 디지탈 전화기(2A, 2B)는 전화교환기(1)에 수신한 버스트신호에 의한 타이밍에 의거하여, 동시에 각 통화 데이타를 포함한 버스트신호를 송출하고, 디지탈회선(4)위에서 디지탈 전화기(2A)에서의 버스트신호와 디지탈 전화기(2B)에서의 버스트신호를 파형 합성하여 하나의 버스트신호를 생성하고, 하나의 베스트신호로 전화교환기(1)에 디지탈 전화기(2A 및 2B)의 통화 데이타를 송신하게 되어 있다.

Claims (5)

  1. 주장치와 그 주장치에서 제공되어 있는 디지탈회선과, 그 디지탈 회선에 직접 다중 접속되어 있는 복수의 단말장치로 이루어진 디지탈 통신방식으로서, 상기 복수의 단말장치들은 소정의 타이밍으로 통신정보를 포함한 버스트신호를 상기 디지탈회선에 송출하고, 상기 디지탈회선상에서 하나의 버스트신호를 생성하고, 상기 주장치는 상기 디지탈회선상의 상기 버스트신호를 수신하는 것을 특징으로 하는 디지탈 전송방식.
  2. 제1항에 있어서, 상기 소정의 타이밍은 상기 주장치에서 수신한 버스트신호에 의해 결정되는 것을 특징으로 하는 디지탈 전송방식.
  3. 제1항에 있어서, 상기 버스트 신호에는 제어용 영역이 포함되어 있고, 상기 주장치는 그 제어용 영역을 시분할하고, 순번으로 상기 복수의 단말장치에 대하여 제어정보를 송신하는 것을 특징으로 하는 디지탈 전송방식.
  4. 제2항에 있어서, 상기 버스트신호는 복수의 단말장치분의 단말정보영역이 있고, 상기 복수의 단말장치들은 자단말장치를 사용할 수 있는 단말정보영역에 자단말의 통신정보를 탑재하는 것을 특징으로 하는 디지탈 전송방식.
  5. 제2항에 있어서, 상기 디지탈회선상에서 송수신되는 버스트신호는 AMI 부호이고, 상기 복수의 단말장치는 상기 디지탈회선상의 앞펄스의 AMI 부호를 기억해두고, 다음 펄스의 극성을 결정하는 것을 특징으로 하는 디지탈 전송방식.
