The 3945 gets you slightly higher FXS/RU density as well as simplified management - ~4:1 management points. It's also more expensive. If you can put value behind either density or management it's worth a look. The 3945 will also have 3945's with PVDM3's. For this application it's basically the same as the PVDM2's, but you could enable some of the 3 features like video switching.<br>

<br>Differences between the PVDM2 and PVDM3's - video support. You'll see these be video transcoders/MCU type resources some time in the future. Possibly some enhanced codec support - namely the dreaded G.729-G.729 capability, and maybe some new codes.

Definitely something to think about for a FAX deployment.<br>
<br>Not quite sure the 3945 bundle is a replacement for a VG224 though. It's 112 ports vs 24.
