Terminal Server Configuration - Remote Devices And Realport - Digi PortServer II User Manual

Terminal server configuration - remote devices and RealPort

In this configuration, several "dumb" terminals are connected to a corporate applica-
tion server by means of a PortServer II and the PSTN (Public Service Telephone Net-
work) or Frame Relay. This example shows that it is also possible to connect a variety
of different devices to the PortServer II in a "dial-up" configuration, including print-
ers, modems, and other peripherals that might be found in a typical branch or satellite
office. Features to note include:
• The corporate application server may be running RealPort software (see Chapter
11, Configuring RealPort Connections).
• PortServer II's Ethernet port is configured with an IP address (see Chapter 4).
• PortServer II and the application server could be connected by a "dial-up" line
(not shown, see Chapter 9, Configuring Modem Connections).
• Terminals, modem, and printer are connected to serial ports on PortServer II.
