- V.terbo mini-FAQ v0.1
- ================ AKA what speed will I get? ----
-
-
- As you all know, the Energis vPoPs have V.terbo modems connected to them.
- These are US Robotics V.terbo, driven at 38400bps. The normal V.terbo
- speed is 19200bps, but USR have their own proprietry extension which
- takes this to 21600bps.
-
- This mini-FAQ lists most of the current high-performance modems and the
- expected connect speeds. It is not a definitive list, and not necessarily
- entirely accurate. However, based on the information I have, I believe it
- is correct. Let me know if something is wrong.
-
- Known modems which connect at 21600bps
- --------------------------------------
-
- US Robotics Courier V.terbo
- US Robotics Courier V.34 (V.Everything)
-
- Known modems which connect at 19200bps
- --------------------------------------
-
- Sonix Volante
- Multitech V.34/V.terbo
- Other V.terbo modems, possibly.
-
- All those which won't handle more than 14400bps
- -----------------------------------------------
-
- US Robotics Sportster V.34 <<<<<<<<<<<<<<<<----------- TAKE NOTE!!!!
- Rockwell chipset-based V.34/V.FC modems including:
- all Hayes modems
- most el-cheapo import modems
- Psion Dacom
- Zoom V.34
- V.32bis modems :)
-
- Modems which, depending on the advert you read, may support V.terbo
- -------------------------------------------------------------------
-
- Pace Microlin fx 34
- Pace Linnet 34 fx
- DFI F1128V+
- Andest Rocket Platinum
- US Robotics Worldport
-
-
- Notes
- -----
-
- Very early US Robotics Sportsters *did* support V.terbo, but this was
- quickly removed.
-
- V.terbo was never an official ITU-T standard and implementations may
- vary between manufacturers. There is no guarantee of compatability.
-
- V.34 includes 21600 and 19200bps as fallback speeds. However, the
- negotiation phase is completely different, and it will not train to
- V.terbo unless the modem specifically supports V.terbo.
-
- The above list does not imply any recommendations. I want a free Courier
- V.34 before I will make one :)
