NM-HDA-4FXS with Voice Gateway 3825

[ecouto]

Hi,

We have a Cisco 3825 (MGCP) with a few E1 and we want to add the NM-HDA-4FXS module to connect modems. We are using Call Manager 6.1. Doesn't anyone know if this will work fine or do we need a different card to connect the modems?

Cheers,

Emilio

Should work, but a better / more modern device would be a VIC-4FXS/DID.

Sound better as they support DID, if the 3825 has 2 x VWIC2-2MFT-T1/E1 cards and 2 x PVDMII DSP SIMM with 4 DSPs. Can I just stick the VIC-4FXS/DID in the HWIC2 module (as I already have som PVDM in the chassis) or I will need to get an NM-HD-2V to support the VIC-4FXS/DID? Any idea?

Cheers,

Emilio

You put it directly into the small slots.

Note DID refers to north america analog DID and it's not likely to be of use to you.

Hi Paolo,

Nice reply indeed. I have always wondered if I have to simulate PSTN on a router with VWIT E1/T1s, how may I do it?

Its for a lab setup

Router1=====> PSTN Emulator<====== Router 2

This would be greatly appreciated.

Hello Wilson,

For a friends lab we used a virtual console PSTN simulator. It worked very well, and along with T1/E1 had FXS ports. Downside is they are a bit pricey, but we were able to find a used one for a couple hundred on the net. Hope that helps!

Thanks J.

Never crossed that idea :-|

I have had heard about the BRI Simulator, however didnt even think about the whole PSTN/Telco simulator (BRI, PRI, T1 CAS and E1-R2 and FXO)

Yes, you can do that.
