Claims (2)

버스 방식을 이용한 T1/E1라인 절체장치에 있어서, 슬롯의 앞면과 뒷면에 유니트가 삽입되는 콘넥터가 부착되며, 공통버스(PL)가 팬턴 형성되어 있는 백 풀랜(20)과, T1/E1연결단자를 각각 가지고 상기 백 풀랜(20)의 뒷면 콘넥터에 부착되어 있으며 상기 T1/E1 연결단자로 입력되는 데이타를 상기 공통버스(PL)과 프론트 유니트로 제1절체 제어에 의해 선택적으로 출력하며, 제2절체 제어에 의해 상기 공통버스(PL)의 신호를 프론트 유니트로 스위칭 출력되어 유니트들(24∼24n+n)과, 상기 백 풀랜(20)의 앞면 콘넥터에 삽입되어 있으며, 각각의 리어유니트로부터 출력되는 T1/E1신호를 처리하고, 공통버스(PL)로부터 입력되는 T1/E1신호를 처리하는 프론트유니트(22∼26)들로 구성됨을 특징으로 하는 버스 방식을 이용한 T1/E1라인 절체장치.In the T1 / E1 line switching device using a bus system, a connector is inserted into the front and rear of the slot, and the back pull-lane 20 having the common bus PL is formed with a pan pulley, and the T1 / E1 connection terminal. Respectively attached to the rear connector of the back pulley 20 and selectively outputs data input through the T1 / E1 connection terminal to the common bus PL and the front unit by first switching control; The switching control outputs the signal of the common bus PL to the front unit and is inserted into the units 24 to 24n + n and the front connector of the back pulley 20, and is output from each rear unit. And a front unit (22 to 26) for processing a T1 / E1 signal and a T1 / E1 signal input from a common bus (PL). 제1항에 있어서, 각각의 리어유니트(24∼24n+n)들 각각이 T1/E1외부 연결단자에 접속되어 이를 단자(A)와 공통버스(PL)에 접속된 단자(B)로 절체하는 제1릴레이(32)와, 상기 제1릴레이(32)의 양단자(A) (B)에 각각 접속된 단자(C) (D)와, 상기 단자(C) (D)의 출력을 프론트 유니트로 접속하는 제2릴레이(42)로 구성된 회로를 적어도 4개 이상 가짐을 특징으로 하는 버스 방식을 이용한 T1/E1라인 절체장치.2. A rear panel according to claim 1, wherein each of the rear units (24 to 24n + n) is connected to a T1 / E1 external connection terminal and transferred to a terminal (B) connected to a terminal (A) and a common bus (PL). The front unit outputs the first relay 32, the terminals C and D connected to both terminals A and B of the first relay 32, and the terminals C and D, respectively. T1 / E1 line switching device using a bus system, characterized in that it has at least four or more circuits composed of a second relay (42) connected to each other. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
