HOW IT WORKS
The multi-user LAN Modem/Proxy solutions are powerful
networking solutions. They provide corporate businesses
and their branch offices a complete networking, fax,
phone and data communications system in one box or software.
This solution is easy to install, use and maintain.
-Whenever any workstation on the network requires access
to the Internet, the LAN modem/proxy server will automatically
dial the Real Image POP and establish a link to the
Internet. This is called Dial on Demand.
From that moment, every machine on the LAN/Proxy can
access the Internet simultaneously.
If one of the workstations has not made use of the
Internet connection for a configurable period of time
(usually two or three minutes), the connection is terminated
automatically by the LAN modem/Proxy Server.
The LAN modem/Proxy server will then connect automatically
This solution uses a Proxy System with ISDN Dial on
Demand, which accommodate multiple users for simultaneous
Internet connectivity with telephone line and one modem.
To implement this system one of your workstations or
server will be designated as a Proxy Server. The workstation
or server will be used for its normally assigned tasks.
Whenever any workstation on the Network requires access
to the internet, the Proxy Server will use the ISDN
Hub to automatically dial the Real Image Internet POP,
and establish a link to the Internet.
From that moment, every machine on the LAN can access
the Internet simultaneously.
- Security, the LAN modem/Proxy server does not accept
incoming calls, this way excluding any possibility
of unauthorised external access
- Routing – the LAN modem integrates a hardware
router; therefore reducing speed connectivity is minimal
regardless of the number of simultaneous users
- Automatic Dial up, launch the Internet browser or
e-mail application and you are on line. No more dial-up
