MAJOR COMMUNICATIONS SOFTWARE HOUSE SHIPS SOFTWARE; ENABLES FASTER INTERNET CONNECT, ETC.VoCAL Technologies Ltd., a supplier of DSP-based communication technologies, has formally released its V.92 modem software suite for existing customers. This new release covers both server and client applications and is an optional upgrade to VoCAL's V.90 data modem A modem used for sending data and not faxes. See modem and fax/modem. protocol stacks The set of protocols used in a communications network. A protocol stack is a prescribed hierarchy of software layers, starting from the application layer at the top (the source of the data being sent) to the data link layer at the bottom (transmitting the bits on the wire). . The software upgrade provides three distinct improvements over present V.90 modem capability. First, the Quick Connect feature virtually halves modem training time from about 20 seconds to less than 10 seconds for subsequent connections to the same server. This feature allows users to get their mail faster or to speed up connecting to their favorite web site. Second, the maximum upstream speed has been increased from 33.6 kbps to 48 kbps. This is becoming increasingly important to those who wish to transfer digital photos to friends and family on the net. Maximum downstream speed remains at 56 kbps under the new specification. A third major feature is the "modem on hold A feature of V.92 modems that allows users to connect to the Internet and switch to an incoming voice call when a call waiting signal is detected. When the voice call is terminated, the line is switched back to the Internet. " capability that allows the modem to work in conjunction with the phone company's call waiting option. This feature enables a PC user to answer a phone call for up to 16 minutes or even more, depending on the maximum limit set by the Internet service provider Internet service provider (ISP) Company that provides Internet connections and services to individuals and organizations. For a monthly fee, ISPs provide computer users with a connection to their site (see data transmission), as well as a log-in name and password. , thereby enabling the PC user to resume surfing surfing, sport of gliding toward the shore on a breaking wave. Surfers originally used long, cumbersome wooden boards but now ride lightweight synthetic boards that allow a greater degree of maneuverability. the Internet after he or she terminates the voice call. The company will further enhance its V.92 software suite with the addition of V.44 data compression data compression Process of reducing the amount of data needed for storage or transmission of a given piece of information (text, graphics, video, sound, etc.), typically by use of encoding techniques. capability, which typically improves data compression by some 20% to 60% over the V.42bis compression scheme employed in V.90--and as much as 200% for certain highly-compressible files. Release of the V.44 package is slated for January 2001. Also under development by VoCAL is V.59, a diagnostic feature that allows the modem to hold previous call information in a buffer so an application on the PC can query it for troubleshooting Troubleshooting is a form of problem solving. It is the systematic search for the source of a problem so that it can be solved. Troubleshooting is often a process of elimination - eliminating potential causes of a problem. purposes. This is an important diagnostic capability for remote access server equipment makers. Release of the V.59 package is scheduled for Q1/2001. |
