Modem F.A.Q.s
Who would have thought something that looked some simple could be so complex. We've gathered together resources to help you de-mystify the modem and your connection.
  • Where do I get information on v.90 upgrade?
    We recommend you read the V.90 Upgrade FAQ available on the internet.

  • What do you mean by analog modem?
    An analog modem is what most people refer to as just "a modem". However, we want to distinguish in this FAQ because digital modems (terminal adapters) thru ISDN are capable of this 56K and greater speeds already. In fact, terminal adapters are not "modems" at all. The word "modem" is an acronym for MOdulator/DEModulator which defines the process by which they work. A modem converts digital computer signals into into sounds (MOdulation) and in turn are transmitted via phone lines to another modem which in turn converted back to the digital signals (DEModulation).

  • What is this new analog modem 56K technology?
    This new technology allows 28.8/33.6 modems to download at 56Kbps. Uploading speeds will remain same at 28.8/33.6Kbps. There are two standards right now: U.S. Robotics X2 standard and Rockwell Semiconductor's 56K FLEX. There is no current industry standard for these similar technologies. The biggest difference between the two standards are that USR's X2 will only upload data up to 28.8Kbps while Rockwell's 56K FLEX will upload data up to 33.6Kbps. Another difference is the Rockwell's 56K Flex seems to get a higher download transfer rates than USR's X2 although neither have been proven to truly get 56Kbps.

  • Does my analog modem support these technologies?
    Check with your manufacturer for which (if any) 56K technology is will be using.

    Check out these pages from Rockwell:
  • Where can I get more information on U.S. Robotics' X2 technology?
    The best place to find information is to go directly to the source. Click here to visit U.S. Robotics Web Page

  • Where can I get more information on both technologies?
    Looking for a non-biased opinion, why don't you see what this site has to say.
