随着程控交换机的普及,交换机的接通率有明显的提高。郑州分局管内程控交换机以S12型为主,经过近年的运用,其运用质量得到各段的认可。程控交换机虽有较强的性能,但若没有进行良好的维护,同样会造成交换机接通率的降低。我们通过对分局程控交换机S12型(7.2版)的维护中,总结出影响S12(7.2版)交换机接通率的一些原因。具体做法如下: 一、对系统状态的观察在硬件上必须保证网络、服务电路模块测试都通过,对不稳定的板子及时更换。对
With the popularity of program-controlled switches, switch-on rate has significantly improved. Zhengzhou branch of the program-controlled switches to S12-based, after the use in recent years, the quality of its use of the approval of the various sections. Although program-controlled switches have strong performance, but if not properly maintained, the same will result in lower switching rate of the switch. We through the branch office program-controlled switches S12 (7.2 version) of the maintenance, summed up the impact of S12 (7.2 version) switch connection rate of some of the reasons. Specific practices are as follows: First, the state of the system observed in the hardware must ensure that the network, the service circuit module test are passed, the unstable board timely replacement. Correct
