If I make a loop on the Digium, I have to set slc= 0 and the channels are OK. If I connect the trunk to the Digium I loose synchronization, but if I connect to the trunk to a yeastar the synchronization is restored.El mié, 23 nov 2022 a las 9:36, Krzysztof Drewicz (<krzysztofdrewicz@xxxxxxxxx>) escribió:Hello,1st check the cables, if you make a loop on your connection - does it clear alarm, both - loop in your Digium Card - should affect the green light indicator, then psychical loop towards your partner - he also should acknowledge on clearing the alerts. Those are baby steps - then - you check the clock, then - you must agree on SS7/C7 connection details, starting from time slots as "0" is considered "1" on some systems.Anyway - this technology is rather obsolete now and even finding a good signalization analyzer or even a E1/T1 connection analyzer (low level link - layer 2 i would say) is hard to find and rather expensive.You must be aware that - 4 electrical lines in cables are being used and every single one of them needs to be good (this is not ethernet, you can't mix pairs...)śr., 23 lis 2022 o 13:28 Storer, Darren <darren.storer@xxxxxxxxx> napisał(a):Definitely check whether signalling is actually on TS16 - quite often it can be on TS1 when working with Siemens EWSD.Regards DarrenOn Mon, 21 Nov 2022 at 13:44, Kaloyan Kovachev <kkovachev@xxxxxxxxx> wrote: Your link is misaligned.

I have put sigchan after the group definition,but the result was the same. I notice in the logs (before and after themodification you suggested) the following message: Huh?! chan_dahdi.c: [11] Huh?! Got FISU in link state 1. I've searched the web but I couldn't find the meaning of this message.
