V.90 vs Flex
- Currently, there are three different 56K protocol available
on the market.
- K56flex: (supported by Lucent Technologies, Inc. and
- X2 (supported primarily by 3Com/U.S. Robotics).
- V.90 This is the new 56k standard.
- Our modems at Indigo are using the latest version of V.90.
They also will connect to modems using the old standard Flex.
- It is a good idea to upgrade your modem to the latest version
possible of V.90. This will give you better connections and
longer online time. (To do this visit your modem manufacturer
- Our modems do NOT support X2. If your modem is a X2 modem
you will only be able to connect at 28.8k
- Because of current phone line limitations, the maximum
speed is 53K, not 56K. (56K is the theoretical maximum speed)
- 56K is only possible in downstream (when you're DOWNLOADING
data) transfer; upstream (when you are UPLOADING information)
is still 33.6K maximum.
- 56K is only possible if you're calling an ISP (Internet
service provider). Two 56K modems calling each other will
NOT be able to reach 56K! This is due to the fact that 56K
technology (both x2 and K56flex) requires a digital connection
(like an ISP) at one end.
