VIC2-2FXS at Cisco 2811 ISR, is NM-HDV2 needed?

Answered Question
Apr 28th, 2010


I have a Cisco 2811 router that is configured as CUCME and working OK. So I need to connect a fax machine so I decided to take FXS card, but I don't know if I need to find NM-HDV2 to get VIC2-2FXS working on 2811, or it works at any of HWIC slots... I have FXO (VIC2-4FXO) working w/o any network module (installed at HWIC slot), so do I need such for FXS?

P.S.: I have PVDM2-8 installed in the router, will it be enough?

Thank you.

The NM is not needed.

The PVDM that you have is enough.
