You aren't "emulating" a particular signalling protocol, you're actually
using it. If you plug two *'s back to back, and are configured for NI2,
you can do a "pri debug span foo" and watch it talking PRI.

But what he said: There are interoperability issues. That's not the same
thing. And NI2 is probably the most common protocol out there - a single
T1 to a carrier, using NI2, is about as likely to work as anything.
