摘要
介绍了一种新型动态“０＋９”数字用户环路复用设备。该设备在数字用户环路复用设备中首次实现了将线路传输容量动态地分配给话音信道，从而使复用设备具有最佳的传输效果。理论分析结果表明，即使在大话务量时，话音质量下降的可能性也只有７．５％。该设备经实际使用后，工作稳定可靠，达到了设计指标。
Introduces a new type of 9-Channel Digital Pair Gain System. At first the systemcan dynamically distribute transmission capacities in a subscriber loop multiplex to every tele-phone channel,so that the system can obtain the best transmission effect.After theoriticalanalysis,systematical construction and working principle of the system are introduced in the pa-per,we also give the real testing results of the system. The results represent that the system isstable at work and satisfying for its design.
