works?
It is an asymmetric client-server transmission scheme that exploioits the 
predominatly digital nature of the telphone network. Provided the server has 
a direct digital connection to the telco network, and there are no 
interveneing analog conversion facilities, the line card at the client's side 
of the link is used a a ditial signal changer instead of a voice band 
coder/decoder. This allows up to 56kbps data transfer rates in the 
server-client direction. In the direction of the clinet to the server, V.34 
technology is used.

One model (the DSVD) does, and it is ironic that it will not be upgradeable 
to the new technology. A ROM swap will be required for the other models.
 JS> So, is it possible, that Supra modems can be easily upgraded by a flash 
rom to this new standard.
No it will not.

It would only be useful to a BBS that already has ISDN capability.   As this 
(if trunk side) meets the requirement of a direct digital link to the 
network, a suitable device could function as an 56kbps server to 56kbps 
capable clients (at present, there is only one capable device in fairly 
widespread BBS host service, the USR Courier I-modem).

No problems at all, hopefully my reply will be as easily understood by you.
