为了解决模拟通信系统与数宇通信系统的对接问题,研制了时分/频分复用变换设备.该设备由PCM复用和2600Hz单频脉冲型线路信令-数字型信令转换两部分组成.经实际应用表明,该系统性能可靠,使用方便.
In order to solve the docking problem of analog communication system and digital communication system, a time / frequency division multiplexing conversion equipment was developed. The device consists of PCM multiplexing and 2600Hz single-frequency pulse type line signaling - digital signaling conversion of two parts. The practical application shows that the system is reliable and easy to use.
