北电设备对接后通道保护的解决方案

北电OM3500与OM4150设备组成的环网和OME6500设备组成的链路均能对其承载的电路实现通道保护切换功能,但这2种设备对接后,穿过环网和链路的电路却无法实现通道保护切换。通过对相应设备的切换状态进行分析,找出了通道保护无法实现的原因,然后根据设备的特点提出了实现通道保护的2种解决方案,同时对这2种方案在带宽利用、抗故障能力方面进行了对比,找出了最优的解决方案。

Solution of channel protection when Nortel equipment connected

Both the ring network composed of Nortel OM3500 and OM4150 equipments and the line network with Nortel OME6500 equipments have channel protection function.But when two kinds of equipments connect together,the channel protection function will be lost.This article first analyses the switch state of correspondence equipments and finds out the reason of losing protection,then presents two kinds of solutions.By comparing the bandwidth utilizing efficiency and anti-malfunction ability,an optimized solution is put forward in the article.
