-002 MUXserver 100 Network Reference Manual

This document is the MUXserver 100 Network Reference Manual, providing comprehensive information for setting up, managing, monitoring, and troubleshooting the MUXserver 100 and its remote DECmux II units. It is intended for server managers responsible for these systems.

The MUXserver 100 acts as a high-performance, low-cost remote terminal server on an Ethernet Local Area Network (LAN), allowing up to sixteen terminals to connect to computer systems and resources. These terminals connect via DECmux II units located at remote sites, using statistically multiplexed synchronous links (composite links, configurable as RS-232 or RS-422). The MUXserver 100 operates as the MASTER, while DECmux II units function as SLAVES.

The manual is structured into several key areas:

• Environment Overview: Explains the MUXserver 100's role in a LAN, LAT architecture, statistical multiplexing, composite links, and the server manager's responsibilities. It details privileged and non-privileged commands and the server's database structure.
• Setup and Configuration: Provides in-depth instructions for configuring login and privileged passwords, server-wide characteristics (e.g., network operation, loading/dumping), composite link parameters (speed, line type, Master/Slave mode), network mapping for logical connections between ports, and individual terminal port characteristics (e.g., access, autobaud, flow control, printer setup).
• Management and Monitoring: Covers commands for security management, controlling terminal user access, broadcasting messages, and remotely managing the MUXserver 100 via Ethernet. It also details monitoring tools (e.g., SHOW commands for counters, nodes, server status, ports, users, queues, and communications links).
• Troubleshooting: Offers a guide to diagnose and resolve problems across various components, including server hardware, composite links, individual ports, service nodes, and the Ethernet. It outlines diagnostic tests and procedures for contacting Digital Equipment Corporation for service.
• Command References: Contains a complete alphabetical reference for all MUXserver 100 commands, including syntax and descriptions, as well as a dedicated section for DECmux II commands.
• Diagnostics and Specifications: Describes available diagnostic tests, categorizes and explains status/error messages from both the MUXserver 100 and its communications processor, and provides detailed hardware specifications for both the MUXserver 100 and DECmux II units.

In essence, this manual serves as the definitive reference for anyone tasked with the technical operation and maintenance of the MUXserver 100 network.
