Hi all
Every time I get a case that a nodeB has its service degraded due to loss of synchronization, I almost have a headache. Usually I search for transmission problems, like a low RX in a microwave link or something like that, but with a low RX in a microwave link it's normal that I got SE, SES or BBE in the node.. but most of the times I got the TRS PM (transmission performance monitoring) clean.. with no SES, ES or even BBE. In this cases, what could be the problem?
Normally, what do you guys search for to solve this problem?
