Multiple FXS ports on a 3745 connecting to PSTN - Urgent!

[j.patmore]

Hi,

I'm putting together a spec to have 35 FXS ports routed directly to the PSTN via an ISDN PRI.

Can anyone foresee any issues with doing this with a 3745, fitted with 3 x NMHDA-4FXS + 3 x EM-HAD-8FXS + appropriate PWDM2 mods + NM-HDV-E1 (or AIM-MFT VWIC?) + appropriate IOS image?

This would be a standalone system (e.g, not controlled by a CallManager), and all the phones will need dedicated lines. And each port will need to be able to generate a line reversal signal.

Any input on this would be appreciated.

Cheers,

J.

If the appropriate IOS images are used with all the supported hardware, then there should not be any issues. Guess, you have enough memory too for the required images.
