            The 
              MultiAccess Communications Server provides built-in V.92/56K dial-in 
              and dial-out modem technology and digital channelized T1 and T1/E1 
              Primary Rate ISDN access in one system. It is ideal for Internet 
              Service Providers and midsize to large corporate intranets requiring 
              network/Internet access for remote offices, telecommuters and home 
              users. As a full-featured remote access server, MultiAccess provides 
              advanced security, web-based management features, and seamless interoperability 
              with any TCP/IP network.

              Highlights 
             Internet 
              Service Providers. MultiAccess offers a rock-solid 
              solution for ISPs. Configure the various line interfaces to suit 
              your environment, plug in your channelized T1 and/or T1/E1 PRI ISDN 
              line and begin servicing your client base. The powerful hardware 
              provides the ability to serve all calls with high performance and 
              maximum throughput. 
              
            Dial-In/Dial-out 
              Simplicity. 
              MultiAccess makes it easy to provide remote access to your LAN for 
              V.92/56K and BRI ISDN remote users. With the potential to support 
              96/120 concurrent sessions, this solution can easily support all 
              of your dial-in telecommuters and road warriors. In addition, LAN 
              users can share the MultiAccess ports for dial-out data connections. 
            Flexibility 
              to Grow. MultiAccess can support up to four digital 
              trunks (T1/RBS and/or T1/E1 PRI ISDN) and provide up to 96/120 ports 
              per rack unit. This allows you to buy what you need today and populate 
              with additional modems as your server needs grow. 
            Versatile 
              Integration. MultiAccess supports channelized T1 
              and/or T1/E1 PRI ISDN services. All necessary software comes preinstalled 
              and ready to be set up for your configuration. 
            WAN 
              Communications. MultiAccess ships turnkey for channelized 
              T1 or T1/E1 PRI ISDN and populated with 24 or 30 universal ports 
              for V.92/56K and BRI ISDN dial-up connections. The high density 
              modems provide V.92/56K dial-up speeds. In addition, they are manageable 
              from remote locations using platform-independent, industry standard 
              protocols. 
            Quick 
              Connect. 
              The quick connect feature reduces the dial-up connection time by 
              as much as 50% for a modem to handshake to an ISP or other connection. 
            Modem-on-Hold. 
              The modem-on-hold feature works in conjunction with call waiting 
              provided by the phone company. Users can answer a new phone call 
              for up to 16 minutes without dropping the modem connection. Users 
              are then able to resume surfing the Internet after they terminate 
              the voice call. 
            V.44 
              Compression. 
              V.44 is a new data compression standard that can improve the current 
              V.42bis data compression anywhere from 20 to 60%, up to as much 
              as 200% for certain types of highly compressible data. This compression 
              technique enables data throughput rates of higher than 300K bps 
              - much faster than today's’stypical rates of 150 - 200K bps. For 
              users, this means that your Web browsing will be much faster. 
            Management. 
              MultiAccess includes robust management support allowing a network 
              administrator to securely manage the devices either through a web 
              browser or at the command line. The browser-based option uses the 
              HTTPS protocol, also known as SSL (Secure Sockets Layer) to provide 
              128-bit encryption to secure the management session. The command 
              line interface is accessible via SSH (Secure Shell) and supports 
              SCP (Secure Copy) and SFTP (Secure File Transfer Protocol) to help 
              provide maintenance support. 
            
            SNTP 
              Support. 
              MultiAccess also has a built-in Simple Network Time Protocol (SNTP) 
              client which enables it to synchronize its clocking with a remote 
              time/clock server on the Internet. This feature is useful for accounting 
              purposes.
