[c-nsp] PSTN network emulation for voice and data

Hi everyone.

I'm looking at putting together a box with some PRI, BRI and FXS interfaces
to act as an "exchange in a box."

Cisco has a 2 port BRI VIC that can do network emulation (VIC2-2BRI-NT/TE)
but I need some help to clarify a point.

It seems that this VIC can be used to allow you to connect terminal
equipment, which I guess could include a router with another BRI VIC, and
place voice calls between the two devices. But, could I take something like
a WIC-1B-S/T and connect it to this VIC to place data calls between a
router and an access server?

Has anyone tried this, or does anyone simply know if it won't work and I'd
be wasting my time/money? Perhaps I would have to configure the BRI to do
DoV to work?
