The NetWare Link/X.25 software subsystem operates in the NetWare 3TM server or NetWare 4TM server standalone router/bridge PC environments.
NetWare Link/X.25 is based on the X.25 standard, which is a set of network interface specifications for packet-switched networks recommended by the ITU-T (International Telecommunications Union, Telecommunications Standardization sector), previously CCITT, in its Recommendation X.25. (The most recent recommendation was the 1988 revision.) The X.25 standard has been adopted by the International Standards Organization (ISO) as the Open Systems Interconnection (OSI) standard for WANs.
NetWare Link/X.25 provides services for NetWare products and other applications (including independent developer applications) requiring wide area connectivity. It uses the 1980, 1984, or 1988 ITU-T Recommendation X.25, which defines the interaction between data terminal equipment (DTE) and data circuit-terminating equipment (DCE) of a packet-switched network. NetWare Link/X.25 implements the X.25 protocol as described in these recommendations, including the Physical layer, Frame layer, and Packet layer, along with several library modules used as an interface to the user applications.
NOTE: DTE is a generic term for any network-attached, customer-premises, or end-user equipment operating in packet mode. A DCE can be any one of the devices that is not a DTE but is associated with a single network port. It is responsible for establishing, maintaining, and terminating the connection with a DTE. X.25 requires a DTE/DCE pair to operate.
Figure 1 shows the wide area connectivity products that NetWare Link/X.25 supports as a software subsystem. These include the following:
