MODEL- SM56USB            VENDOR- DIAMOND MULTIMEDIA

FEATURES- SupraMax External USB 56K Modem
       External USB modem with V.92 compatibility.
       Diamond Supra unleashes the highest performance SupraMax modems with
        newly adopted ITU, V.92 and V.44 compression standards.
       SupraMax gives you the advantages of extensive analog access to the
        Internet with an added boost of speed over earlier standards. These
        improvements include accelerated upstream data transfers (up to
        40% faster), faster Internet dial-up connection times using an
        intelligent start-up sequence, and advanced compression algorithms
        that let you send common file type (such as HTML, e-mail, and
        executable files) more efficiently.
       The Modem-On-Hold feature lets you receive incoming voice calls
        without dropping your current modem connections. And, because the
        SupraMax V.92 is backward compatible with V.90 and earlier
        standards, you can relax and enjoy faster Internet speeds without
        worry.
* V.92 is an International Telecommunications Union (ITU) standard for
  analog modem connections, a new improvement over the existing V.90.
  Though the top speed for downloads is still 56K, V.92 has a number of
   enhancements.
* There are four important benefits to the V.92 standard; Quick Connect,
  Modem-on-hold, PCM upstream and V.44 data compression.
  - Quick Connect - by reducing the amount of time it takes for the modem
    and server to handshake, connect time is reduced dramatically. Instead
    of taking around 25 seconds to connect, this may be reduced to 8
    seconds.
  - Modem-on-hold - the end user can put the modem on hold and stay
    connected to the Internet. The user can take an incoming voice call, or
    even place a call while still connected. When the call is through, the
    end user can resume Internet activities without having to re-dial and
    connect.
  - PCM upstream - increases maximum upload speed to 44 Kbps.
  - V.44 - a standard for data compression specifically for HTML (normal
    website), text and other common file types, for faster downloads.
    Throughput can increase up to 30-40%. This will supercede the current
    V.42bis standard.
* Your ISP carrier must provide support for V.92 and V.44 compression.
  Please consult with your ISP for details.
