Abstract

본 발명은 전송방식의 하나인 펄스부호변조 전송장치에 있어서, 특히 종래의 장비에서는 보드당 3가입자를 수용하던 것을 15가입자 까지 수용할 수 있도록 장치를 구성함을 특징으로 하는 펄스부호변조 전송장치에 관한 것으로, 기존의 펄스보호변조 전송장치 시스템은 보오드당 3가입자를 수용하여 시스템의 가입자가 증가함에 따라 시스템의 부피가 커져서 설치하는데 많은 면적을 차지하고 가격의 상승을 초래하는 문제점이 있어, 본 발명은 보오드당 수용가입자의 수를 늘림으로써, 보오드 및 셀프의 증축을 줄여 싼가격으로 많은 가입자에게 전송라인을 제공토록 한 것이다.The present invention relates to a pulse coded modulation transmission device, which is one of transmission methods, and particularly, to a device for accommodating up to 15 subscribers having accommodated 3 subscribers per board in conventional equipment. In the related art, the conventional pulse protection modulator transmission system has a problem of accommodating three subscribers per board and increasing the number of subscribers of the system, thus increasing the volume of the system and increasing the price, resulting in an increase in price. By increasing the number of subscribers per board, we have reduced the number of boards and shops to offer more subscribers at lower prices.

Claims (1)

각각 15가입자를 수용할 수 있는 입출력포트가 교환기가 결합하여 교환기에서 나오는 아날로그 신호를 입력받아 대역필터링 후 8KHz로 셈플링하고, 펄스부호변조의 코드로 변환한뒤 각 채널별 할당시간에 8비트 데이타를 송수신장치로 송출하며, 또한 송수신장치에서 오는 펄스부호변조 데이타를 입력받아 아날로그 변환뒤에 교환기로 전달하는 채널장치(10A, 10B)와; 상기 채널장치(10A, 10B)의 두개를 결합하여, 채널장치에서 수신된 펄스부호변조 데이타를 펄스부호변조 포멧의 각 할당 타임슬롯에 삽입하고, 프레임 동기신호 및 각 채널의 상태정보를 삽입하여 E1 라인을 통해 대국의 장치에 전송하며, 또한 대국으로부터 수신된 E1신호를 입력받아 각 채널에 데이타와 상태정보를 송수신하고, E1신호를 감시하여 노우데이타, 경보포착, 프레임에러등을 경보장치에 전송하며, 각종 에러발생시 교환기 및 대국의 영향을 미치지 못하도록 처리하는 송수신장치(20)와; 상기 송수신장치(20) 5개와 결합하여 각각의 송수신장치에서 송신된 경보신호를 받아서 RS- 232를 통해 사용자에게 각종 경보상태를 송출하고, 가청 경보를 발할 수 있도록 경보장치에 송출하며, 또한 사용자의 명령을 받아서 로컬 루프백과, 리모우트 루프백 및 에러체킹을 실행할 수 있도록 송수신장치(20)를 제어하는 커멘드 컨트롤 장치(30)와; 상기 커멘드 컨트롤 장치(30)에서 송신된 경보를 사용자에게 가시, 가청할 수 있는 경보를 발하는 경보장치(40)로 구성함을 특징으로 하는 펄스부호변조 전송장치.Input / output ports capable of accommodating 15 subscribers each are combined with an exchanger to receive analog signals from the exchange, sample them at 8KHz after band filtering, convert them into pulse-code-modulated codes, and then assign 8-bit data to each channel's allocation time. A channel device (10A, 10B) for transmitting the signal to the transceiver and receiving pulse code modulation data from the transceiver and transferring the analog signal to an exchange after analog conversion; By combining two of the channel devices 10A and 10B, the pulse code modulation data received from the channel device is inserted into each allocation time slot of the pulse code modulation format, and the frame synchronization signal and the state information of each channel are inserted to E1. It transmits data and status information to each channel by receiving the E1 signal received from the power station, and transmits no data, alarm capture, and frame error to the alarm device through the E1 signal received from the power station. And a transmission and reception device 20 for processing so as not to affect the switch and power when various errors occur; In combination with the five transceivers 20 to receive the alarm signal transmitted from each transceiver transmits a variety of alarm status to the user via RS-232, and to the alarm device to issue an audible alarm, A command control device 30 for controlling the transceiver 20 to receive a command and execute local loopback, remote loopback, and error checking; And a warning device (40) for generating an alarm that can be audible and audible to the user of the alarm transmitted from the command control device (30). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
