For some work i'am trying to connect to Asterisk's PBX using isdn cards.

Are you trying to connect 'to' Asterisk PBXs or 'two' Asterisk

It's 2 T1/E1 cards!
Specifically, on of it is a TE110P and the other is a TE122!

Thank you for the answer i tried this, and it works well ( Two servers are
synchronized). Now i want to make a call between the servers. I have a sip
