Figure 1-1 Solstice X.25 Overview

Solstice X.25 9.2 is an implementation of the ITU-T's (formerly CCITT) X.25 Recommendations, together with some other, related software. Using Solstice X.25 9.2, you can make connections to a Packet Switched Data Network (PSDN), and connect to remote devices that are running any standard-compliant implementation of X.25.

Figure 1-1 shows some of the ways you can use Solstice X.25 to make connections with remote devices:

• PAD calls from Sun workstations running Solstice X.25 to Sun workstations and servers running Solstice X.25, and to remote systems running other implementations of X.25.

• PAD calls from one X.25 device to another, from where the user can rlogin to a non-X.25 IP host.

• uucp connections with remote X.25 devices.

• IP routed between TCP/IP networks.

All of the connections shown in the diagram are made across the X.25 PSDN.
