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