Hi Matthew! I am running my SG (Signalling Gateway ) Stack on Power PC 8260 Processor (Embedded Linux). OS is embedded Linux. Signalling link is up between SG Statck and another SS7 Stack. When I run some load through SS7 Stack, after some time the Signalling Link goes down. I found the problem, the problem is happening at MTP2 level. The link is failing due to receiving of incorrect FIB (Forward Indicator Bit ) and / or BSN (Backward Sequence Number) at MTP2 Level. According to recommendation Link can go down. Now my query is, what can be the problem, is it on my end or remote end, and how can it be resolved if possible.
