PRO175 PRO/DECnet Version: 2.1, October 1989 Submitted by: Digital Equipment Corporation Operating System: P/OS V3.2 Memory Required: 512KB Software Required: DECUS No. PRO177, P/OS Version 3.2 Keywords: Networking, Professional 300 Series - P/OS Abstract: PRO/DECnet enables a Professional 300 Series System to participate as a non-routing (end) node in DECnet computer networks. The Professional node can communicate with other DECnet nodes using either the Communications Port (COMM1) for Asynchronous or Synchronous DDCMP Wide Area Network communications, or the NET1 Port for Ethernet Local Area Network communications, but not both at the same time. The optional PRO/Tool Kit, see DECUS No. PRO178 for a description of this package, contains libraries which allow developers to write applications which communicate in a DECnet network. PRO/DECnet Phase IV networks can contain up to sixty-three network areas, with a maximum of 1023 nodes per network area, given proper network planning. Phase III nodes participating in Phase III/IV networks are limited to the Phase III routing capability of 255 nodes. Phase II nodes are not supported. Phase IV end nodes not directly connected to an Ethernet Local Area Network must connect to a Phase IV full function (routing) node, and can only communicate with Phase III nodes through such a router. The functions available to the PRO/DECnet user depend largely upon the configuration of the rest of the network. Each DECnet product offers its own level of capability and its own set of features to the user. Functions available with PRO/DECnet include Remote DECnet Terminal Utility, Remote File Access and File Transfer, Mail, Phone, Modem Support and Task-to-Task Communication and Network Management.
