[AusNOG] Cisco BRI Acting as Provider

[Tom Storey]

VIC2-2BRI-NT/TE can emulate line side. There is a command you can use
to turn on line power.

It does only seem to support voice calls, though.

Ive been playing around with one in my lab, hooked up to an 1841 with
an BRI WIC but have been unable to successfully pass a data call
through the VIC, out of a PRI and in to another router with a PRI. The
call seems to get routed through properly, but evidently theres
something about the contents, or other headers used in a data call
that the VIC just doesnt cooperate with. :-(

The config is quite trivial, seems almost too easy really.

(I was hoping to build myself a PSTN emulator with BRI, PRI and POTS
lines on it, but using Cisco gear that I already own. A box like this
is either hard or impossible to find, and very expensive if you can.
What I have built will be fine for voice scenarios, but was hoping to
use it for ISP/data scenarios too.)
