摘要
主要介绍了宽带网双向传输中汇集噪声、汇集均衡、网络安全 3大技术难点产生的主要原因及解决办法 ,并介绍了集中分配的工作原理、具有的特点以及网管系统的主要功能 ,最后重点对集中分配方式上、下行信号电平的调试作了较详细的介绍。
It is introduced that the main reason of collective noise, collective balance, net safety in bidirectional transmitting of broadband net and its solution. The work principle of centralized distribution pattern, its character and the main functions of net management system are discussed. The adjustment of up, down level signals in centralized distribution pattern is explained in detail.
