It should be 1 to 4 and 2 to 5, not 3. The pairs are 1-2 and 4-5.


Hi,
Using a DIUS2 on the Hicom, you have to loop 3-10 and 7-14.   .
Using a DIUN2 on the Hicom, the loop is not necessary.
 
BTW 1-9 is Tx and 7-14 is RX.
 
hope it will help.

That should have worked, as long as 1-1, 2-2, 4-4 and 5-5. Are you sure 
the signalling is correct? What did zttool say?

Yellow alert is remote alert, right? That would indicate that the path 
from the pbx to asterisk is ok, but not the path from asterisk to the pbx.

Do you have crc4 enabled? Care to post your zaptel.conf.

I think you have to start asterisk on the span to get the upper layers 
enabled.
