Hi everybody,
After some advice from you, we changed the order of my spans in the card.
It was in slot 5 in this order. T1 (channelbank) T1 (channelbank) E1 (empty, with a loopback for testing porposes) E1 (Telco - PRI/ISDN)
Now it is this way E1 (Telco - PRI/ISDN) E1 (empty, with a loopback for testing porposes) T1 (channelbank) T1 (channelbank)
But when I chaged the order, I got too many lost interrupts. So I begin to chage slots and it gets OK in slot 2. I can sync to telco's clock as we hope!
So, if you are having some problem - I think any kind of problem like interruptions, clock slips, HDLC (Abort and Bad FCS) - try EVERY configuration set as possible. I mean fisicaly configurations. try slot 1, 2, 3... every thing you can.
Ok. It sounds like a Mandrake solution :-), but it can solve your problem.
Thanks to everybody how helped me. -- Alex G Robertson NOC - Microlink
