Hi arvind,
where are you using libss7 Powerpc side ?
and what is the physical connection between sg and the ss7 stack(is this libss7)
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.
Thanks in Advance
Regards,
Arvind

Hi!
Could you please help me.
I running load on SS7 Signalling Link. After some time the link is going
down,
I identified it is going due to abnormal FIB, 2 out of 3 FIB are not proper.
It is ok according to
ITU recommendation,
I want to resolve this problem. I want to know whether this is problem with
my stack or another side stack or something else like clock etc. Kindly
help.
Thanks &
With Best Regards,
Arvind

Can you explain further what you are talking about? Your description of
the problem doesn't seems sufficient to explain what's going on.
Also, what stack and setup are you using?
Thanks.
