Some of the information I was looking for.

-| With the BRI card you can simulate a PRI if the BRI card is smart enough.

server.

The Internal BRI card handles the BRI's why should I need ISDN modems as
well? I would use the BRI's for customers in New Mexico, if customers ask
for the service. I do run regular external modems, and know they are
cheaper than BRI's.

I've seen equipment that muxes BRI's into a PRI. Your costs only take into
account recurring costs for a PRI versus multiple BRI's. They do not take
into account the cost of a new PM3 versus the one already owned as well as
the muxing equipment, and the reduced number of BRI customers due to the
high cost of a BRI in New Mexico.
>1.) ISDN is REALLY new in NM to USWest -- their success rate on first

As in any endeavor I would have the new service up and working before
turning it over to customers for service.

Is this any different from service with regular analog lines? Again make
sure it is working before letting customers loose on the new service.
-| I'm not looking to get rid of the PM2's, they aren't limiting me, I want
to

Of course that is the plan. Low usage locations in the first place,
hopefully support for the product. A separate rotor for ISDN and Modem
access, coming in on the same piece of equipment. Eventually with 10 analog
lines, and 5 BRI's in service, I have a business case and usage case to
upgrade to a PM3 with PRI service and internal digital modems, with one
number to call.
