Wow you're the first person I've seen using a combination of T1 and E1 on the same card. I wonder if this has something to do with it (i.e. a bug in the drivers).
I'm assuming you have the jumpers for span 3 and 4 closed in order to get E1 operation on them (I doubt it would work this far without).
Yes. Jumpers are ok.
I would certainly be contacting Digium about this. Span 4 being the only clock=1 should work just fine.
I am. I'm in contact to Digium support. They also don't know what is happening. The problem appear exactly when I cofigure span 4 as clock = 1.
It just don't synchronize. Telco keeps sending yellow alarm because of clock difference.
When clock on span 4 is set to 1, telco bit rate stays at 2048000 bps and mine at 2048443 bps.
Just for fun, you might want to try putting span 1 as your E1 uplink, span 2 as your E1 loopback, and span3 and 4 to your T1 channel banks.... Just for trying to sort this out (remember to adjust the jumpers if you do this).
I have already done that, but to verify another situation. I was receiving too many HDLC errors, and fo this problem nothing changed.
I will try that and send the result..
