[asterisk-ss7] link is down

[Pawel Ratajewski]

the problem appears one day after signalling and billing tests have been 
done (result - passed of course), I'm not sure if exists earlier. The strage 
is, it appears only sometimes - eg. yesterday links worked fine for whole 
day. Problem is not related with extra load (all cics were used during 
billing test, and everything was fine).

system load is minimal:
13:40:10 up 3 days, 4 min,  2 users,  load average: 0.04, 0.07, 0.01

I use Sangoma A101 (single e1 port) card.

Krzysztof - I have asterisk boxes with chan_ss7 and libss7 with other polish 
telcos - gts and exatel (since 2007) :)

The problem is definitely  by my side - I set port as a master (TE_CLOCK= 
MASTER) and insert loopback into e1 port (and set opc=dpc) and link also 
went down after 2h.
The same version of chan_dahdi, asterisk and chan_ss7 I have installed on 
other box connected to other telco and it works well. Can It be a problem 
with the card?

Pozdrawiam / Regards

To many errors on your link, you got this link working and it's having
some extra load? (like too many calls, attempts to make a call?) or
you try to run it for the 1st time?

Maybe load on your box is too big. What does other party see? TK is
like TK Telekom so, you make link with polish railways :D good to know
that they do support SS7.

Rest is saying no other singling link, so shutdown whole linkset.

Tried libss7? What hardware (orginal digium or a cheap clone?) and how
many cards / E1 on one box, what load in means of traffic etc...

Give us some more info, right?

Nice to see a lot of guys from Poland here, but try not to use our
national chars like o' l/ z', most of the world does not know even how
do display them.
