This document describes DECnet/OSI Version 7.0 for OpenVMS VAX, an implementation of the Digital Network Architecture (DNA) Phase V. It integrates DECnet and Open Systems Interconnection (OSI) protocols, allowing multi-protocol operation, including support for TCP/IP transports. The software supports a wide range of VAX hardware and includes advanced network management (NCL), naming services (DECdns, DNS/BIND), file transfer (FTAM, DAP), and Virtual Terminal capabilities. It covers installation requirements, hardware and software dependencies, X.25 configuration guidelines, and software licensing information.
