Abstract

본 발명은 디지탈 가입자 라인 선택장치에 관한 것으로서, 이는 가입자의 채널 데이타 속도에 따라 운용모드를 4선식 또는 2선식으로 적절하게 변경시켜 N*56/N*64에서부터 T1/E1까지의 다양한 가입자의 데이타 속도에 대하여 대응하도록 한 것이다. 이와같은 본 발명은 2선 모드시, 외부의 프레임 클럭에 의해 타임슬로트를 제어하는 타임슬로트 제어수단과, 상기 타임슬로트 제어수단에 의해 라인 접속되어 송신데이타를 인터페이스하여 트렐리스코더 및 타이밍 회복수단, 제2송신수단, 제2HDSL선로 접속수단을 통해 리모트측으로 전송하고 그 리모트측으로부터의 상기 역과정을 통해 얻어진 신호를 타임슬로트에 전송하는 N*56/N*64접속수단을 포함함으로써, 달성된다.The present invention relates to a digital subscriber line selector, which changes the operation mode to four-wire or two-wire according to the subscriber's channel data rate so that data of various subscribers from N * 56 / N * 64 to T1 / E1 can be changed. It's about speed. In the present invention, in the two-wire mode, a time slot control means for controlling a time slot by an external frame clock, a line connected by the time slot control means to interface transmission data, and a trelliscoder and And N * 56 / N * 64 connection means for transmitting to the time slot the signal obtained through the reverse process from the remote side through the timing recovery means, the second transmission means, and the second HDSL line connecting means. This is achieved.

Claims

Demultiplexing means and multiplexing means for demultiplexing and multiplexing transmission data and decoded received data through a digital line connection means, a trelliscoder for coding and decoding the data and the received digital signal obtained from the demultiplexing means; Converts the timing recovery means and the coded data obtained from the trelliscoder and the timing recovery means into an analog signal, and transmits it to the remote side through the first and second HDSL line connecting means and converts the analog signal received therefrom into a digital signal. First and second transmission means for converting and inputting the trellis coder and the timing recovery means, the time slot control means for controlling a time slot for controlling the time slot by an external frame clock, and the time slot. The line connection is made by the trajectory control means to interface the transmission data so that the trellis coder and the timing recovery means A digital subscriber comprising N * 56 / N * 64 connection means for transmitting to a time slot a signal obtained through the reverse process from the remote side and transmitting to the remote side through the second transmitting means and the second HDSL line connecting means. Line selector.

2. The digital subscriber line selection apparatus according to claim 1, wherein only the time slot control means and the N * 56 / N * 64 connection means do not operate when the subscriber mode is a four-wire mode.

2. The digital subscriber line selection according to claim 1, wherein only the digital signal connecting means, the demultiplexing means, the multiplexing means, the first transmitting means, and the first HDSL line connecting means do not operate when the subscriber mode is a two-wire mode. Device.
