Claims (4)
- 저주파수 음성 대역의 시험 톤을 발생시키는 시험 톤 발생 장치와, 두 회로 간의 전력 손실을 가장 적게 하기 위하여 삽입하는 E-1 정합회로를 각각 구비하는 액세스게이트웨이 및 디지털 교환기와;상기 액세스게이트웨이와 디지털 교환기를 연결하는 E-1 디지털 전송로; 및상기 E-1 디지털 전송로 상에는 특정 주파수 만을 통과시키는 음성 대역 필터를 내장하고 루프백 기능을 하는 다수의 중계기로 구비되는 것을 특징으로 하는 액세스게이트웨이 시스템의 E-1 디지털 중계기 선택 시험 장치.
- 제 1 항에 있어서,상기 시험 톤은 상기 음성 대역 필터를 통과하여 차순의 중계기로 송출되는 것이 아니라, 상기 중계기가 시험 톤을 병렬로 처리 하여, 차순의 중계기로 시험 톤을 전달하면서 음성 대역 필터에서 검출 하는 것을 특징으로 하는 액세스게이트웨이 시스템의 E-1 디지털 중계기 선택 시험 장치.
- 제 2 항에 있어서,상기 음성 대역 필터에서 시험 톤이 검출되면,상기 중계기는 루프백을 하여 상기 시험 톤이 이전의 중계기로 송출되는 것을 특징으로 하는 액세스게이트웨이 시스템의 E-1 디지털 중계기 선택 시험 장치.
- 제 1 항에 있어서,상기 중계기의 음성 대역 필터는,타 중계기의 음성 대역 필터와 서로 다른 주파수로 설정되어 있고, 각각의 음성 대역 필터는 주파수를 필요에 따라 변동할 수 있는 것을 특징으로 하는 액세스게이트웨이 시스템의 E-1 디지털 중계기 선택 시험 장치.
