SCTP Link Fault

[sackyharrey]

Hello everyone,
I'am having intermittently SCTP Link Disconnection with this alarm: "SCT Link Fault" on a NodeB (BTS3902E Huawei).
We have this Issue few days after activating the 2G bts( BTS3900E). these two are connected to a RTN905 equipement( Port 1:2G, Port 2:3G).
During disconnection time, i can ping the Gateway but not the BSC adress.

some ideas??
