> A) what are V.32, V.32bis, V.42, and V.42bis

V.32 - 9600 Bd full duplex
V32bis - 14400 Bd full duplex
V42/V42bis - data kompression (like MNP, partly including MNP)

> B) which of these does Telebit support?

T2500 has V32, at least V42, maybe 42bis, but I'm not sure...

All.

Sure, see above...

In the moment, I think the decission between a Telebit or USR Modem will 
probably not bee too hard (IMHO).

- Telebit is rather high priced compared with the HST/V32/HST DS modems 
  (especially when using the USR SysOp Support Program, which reduces a DS's 
  price to somewhere below $700)

- though Telebit support protocol spoofing (local ACK of data packages when 
  using slow protocols like UUCP-F/G, Kermit or XModem) and result in pretty 
  good CPS rates, USR with its V32bis has pulled equal.

- when calling systems that do not run Unix, USR is clearly the market 
  leader (I once heard that USR had a market share of over 80% of the High 
  Speed Modems)

- no matter which one you select, it should have V32, as this is the only 
  way to connect with other companies' high speed modems above 2400 Bd
