asterisk users - Jul 2005 - TDM22B - asterisk and seimens hipath 3750

Hello
        I am planning to build a small PBX using
TDM22B.

We have a Siemens Hipath 3750 in operation
already.

When I manage to complete my PBX using TDM22B
I would ofcourse like to be able to connect my Asterisks PBX
with the Siemens Hipath 3750 PBX.

Will there be any issues regarding my plan ?
Or is there any other issues that I need to take
into account vis-a-vis Siemens PBX.

I have never done all this before so I would 
appreciate all inputs.

Thanks in advance

Varun
