As i said - master clock problem: your Yeastar provides the master clock
and both Digium and Siemens are slaves
change you system.conf
form "span=1,1,0,ccs,hdb3"
to "span=1,0,0,ccs,hdb3"

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.

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...)

Definitely check whether signalling is actually on TS16 - quite often
it can be on TS1 when working with Siemens EWSD.

Thanks for your time. I have put sigchan after the group definition,
but the result was the same. I notice in the logs (before and after
the
modification 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.

Hello,
put sigchan after the group definition:
group=1
cicbeginswith=1
channel => 1-15
cicbeginswith=17
channel => 17-31
sigchan=16
for now remove the slc line and check the configuration on the other
side: if it is configured to use different slc, then add it before
sigchan

I have a Digium TE122 whith one span connected to Siemens switch. As
I
got the message "ERROR[20309] chan_dahdi.c: [1] Received message for
slc 0x1, but we are 0x0. Dropping" I changed slc to 1 in
chan_dahdi.conf. But now I get this message; "ERROR[20309]
