Publication Date:  2012-08-12 Views:  52 Downloads:  0
Issue Description
Services are interrupted when SD or SF occurs on the active and standby units of client-side 1+1 protection that are located in two NEs.  
Alarm Information
Null 
Handling Process
Ensure that either of the active and standby units works normally.  
Root Cause

The following figure shows the scenario in which the active and standby units of client-side 1+1 protection are located in two NEs. When SD or SF occurs on the active and standby units, the NE software cannot manage cross-NE operation and shut down the lasers of the corresponding ports of the active and standby units. Thus the services are interrupted.
