SupraMax PCI LE 56K Modem
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 includes 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 new 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. (For more information on V.92 features, please see below.)
WHAT IS V.92?
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.
WHAT FEATURES ARE INCLUDED IN V.92?
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 new 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.
WHAT IS REQUIRED FOR V.92 AND V.44
Your ISP carrier must provide support for V.92 and V.44 compression. Please consult with your ISP for details.
