摘　　要：针对K接口用户远端长距离接入的需要,并结合对K接口数字基带通信信道误码产生特性的分析,采用数字信号处理器(DSP)、大规模集成电路及复杂可编程逻辑器件(CPLD),设计了一款多用途K接口用户线路中继器。该中继器不仅能实现K接口用户超长距离的可靠稳定接入,还能实现对K接口信道数字传输中的误码模拟,以有效辅助用户实施对各种K接口通信设备的超远距离接入应用和抗误码性能测试。Aiming at the requirements of K-interface user remote access, based on analysis of the characteristics of K-interface digital baseband communication channel error, and with DSP （ digital signal processer） ,large-scale IC and CPLD （complex programmable logic device） , a multi-use K-interface subscriber line repeater is proposed and designed. The repeater can achieve stable, reliable and long-distance access by K-interface user and realize the error simulation of K-interface channel in digital transmission, thus to effectively support users in their implementing the remote access application and anti-error performance test of K-interface communication equipment anti-error.
