E911 caller id, what do i need

[mike101876]

I am trying to allow the caller id to pass between my opting 11 to a mitel PBX. currently i have a point to point TIE line connecting them. what is the best solution to allow my system to pass the caller id on a 911 call to the Mitel. do i need a pri instead. the option 11 is a remote node and there are severalother systems that are connected to the mitel.

I would use a PRI with QSIG and CLID

Thank you, I also have another question to this, this is a dual cabinet option 11 and i have a spare dti/pri card on hand. is it possible for me to build this PRI as a second connection and later remove the tie line or would it be best to convert the tie to what i need, please keep in mind i am completly unexperienced at working on pri circuits.
