摘要
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．
To solve the interface problem in analog junction of swiching system and digital junction of another swiching system, a TDM/FDM transmultiplexing equipment is disigned. The equipment consists of PCM multi--channel multiplex and 2 600 Hz single frequency pulse line signalling--digital signalling conversion.Through practice it shows that the system is reliable and easy to operate.
