Indeed it does. A BRI is as "trunk side" as it gets. The B channels
are pure digital.

Indeed the entire USR I-modem family will support x2 56K analog server
mode.
2E users can front-end it with the USR MP I-modem. It will take
digital calls and analog calls dynamically on each port. It will
definitely support x2, and be flash upgradeable when a standard is
agreed upon. I personally expect the standard to take a long time, so
I would not want to wait that long to get something implemented for
your customer base.
Also, the analysts seem to think that USR has a 6 month jump on
Rockwell/Lucent, and as it is a flash process with USR (as opposed to
a hardware swap for Rockwell/Lucent hosts) widescale deployment of x2
will be much, much faster. Probably on the order of a full year in
many areas.
Lastly is the problem of when a standard is agreed upon, many
rockwell/Lucent users will have to upgrade their hardware again, with
USR it is a flash. Even if they pull off a flash process, that is new
to many of them (not USR), and they will be fighting those issues
along with catching up on 56K technology.
This will be a simple upgrade for 2E users without having to trash
your entire setup! Basically, don't trash your 2Es, just upgrade the
front-end with an MP I-modem (or single I-modem to try it out).=20
