Communications Server Configuration - Dial-Out Access To The Internet - Digi PortServer II User Manual

Communications server configuration - dial-out access to the
Internet
In this configuration, several satellite or remote users are provided with access to an
ISP (Internet Service Provider) by a PortServer II and the PSTN (Public Service Tele-
phone Network) or Frame Relay (see Chapter 14). This permits the user full access to
all Internet options, including e-mail and World Wide Web (WWW) if they have the
appropriate software installed on their terminals. Features to note include:
• PortServer II is configured to provide a dial-out PPP link to the ISP.
• The link may be available at all times, only at certain times, or only on demand,
depending on traffic and billing considerations (see Chapter 8).
• PortServer II is connected to the local user's terminals by Ethernet.
• It is not necessary for local users to log into the Internet service individually. Port-
Server II will log in for all configured users (see Chapter 9).
