Is there any upgrade or exchange program for the regular bitsurfer?

Not that any of us early adopters out there on the bleeding edge know

If you open up the BitSURFR and BitSURFR Pro (I don't recommend this) you will
see the two units have radically different PC boards.  Also, the BSPRO has two
CPU's where the BS has only one.  No upgrade there.

       Quite true. Before the Pro was released, there was
some idle chatter in comp.dcom.isdn about firmware upgrades
to turn vanilla BitSURFRs into Pro units. That didn't ever
happen, and Motorola (unjustly) took some heat over it.

       The reason why it never materialized was made
clear when I got a chance to look at the internals of a
production Pro, shipped to InterNex for productization work
with our service. It's quite different from an engineering
perspective, making it entirely impossible to simply do an
upgrade from the old architecture.

Indeed, you can't turn a BS into a BSpro. You can however turn a BS into
something that will do some of the things a BSpro does. FOr $60 you can an
EPROM upgrade to make your (older) BS do BONDING, and that means you can
talk to other BSpros at 115.2Kbps, making a BS much more useable.

One must be careful when using the term BONDING.  Yes the BitSURFR will use
some bonded protocols, but not all.  Strictly speaking, BONDING is a
synchronous protocol for connecting "clear channel" links.  The acronym
BONDING stands for Bandwidth On demaND INteroperability Group.  Since
this protocol is synchronus and has no rate adaption protocol, it will
work at channel speeds of 56, 64, 112, and 128kbps only and both TA's DTE
ports must be set to the same speed.

There is an asynchronous bonded protocol called AIMux (Async Inverse
Multiplexing) that the BitSURFR Pro and upgraded BitSURFR will support.  This
asynchronous protocol has rate adaption so you can connect TA's running
different DTE rates up to 115.2kbps.  I believe this is the protocol to which
you are referring.

The BitSURFR will never do PPP bonding, however, because it dosen't have the
hardware.
