ADM Ring

ADM Ring

Hi friends,

I have a STM1 SDH ring with 13 nodes. Each node has a ADM, ADR-155c, and lately I am having some problems of RS and MS degradation. Also one of the ADM is been reset suddently sometimes lossing its configuration mysteriously, and having to be mannually recover. This ADM has failed again but this time I cannot recover because when I try to setup a cross connection the ring became unstable, I mean when I create a connection from this ADM after some seconds, 45-60, some others connections in the rest of the ring start to fail. As soon as I delete that new connection the failing connections in others ADM recover inmediatly.

I am suspecting a synchronization problem. Can any of you give me some help?
