Microcom HDMS Modem Management System
Part Number: MCR-1285030

Microcom HDMS Intelligent Network Controller. The Controller Card and Adapter Supports Eight Chassis (254 Modems) and Features Security Management, Configuration Management, Real Time Alarms and Summary Reports.


The Microcom HDMS plus (TM) (High Density Management System) is a modem management system for dial-up networks. It provides operational statistics, security, modem control, real-time monitoring and configuration of multiple channels in a single system. The HDMS plus eases network growing pains, providing comprehensive network management and security capabilities for central sites. When you install an HDMS, you effectively bring in extra networking staff on duty 24 hours a day to monitor your modem network. Not only does this "extra staff" recognize immediately when a problem occurs, it is also able to swiftly isolate the problem, call for help and take immediate action so that modem users on the network are not inconvenienced by down time.

Until HDMS, network managers had few choices when they wanted to expand their dial-up modem networks. To increase host capacity, they simply purchased new modems. The result was a hodgepodge of modems stacked haphazardly on top of each other. Not only did the modems occupy significant amounts of space, but when a modem failed, it was difficult to isolate and quickly troubleshoot the problem. The result: an inefficient network, a frazzled manager and frustrated users.

Intelligent Network Controller (INC)

The "brains" of the HDMS, the INC, provides real-time monitoring of EIA-232 signals, alarms, statistics, diagnostics, modem set-up and remote standalone configuration capabilities. The INC also provides dial access security with event logging, port grouping and clocked operations.

Operators can access the INC using a VT-100 compatible terminal or Microcom's PC-based HDMS/Relay (TM). Based on RELAY communications software, HDMS/Relay is a data management application that allows operators to collect HDMS data and alarms and back-up system configurations on a PC.

Additional features include: threshold processing with remote alarm posting, dry contact alarm relay and automatic remedial action.

The INC negotiates supported features with each HD modem in the system. Any HD modem can be installed in any chassis slot allowing for mixing and matching of modes and security types. More importantly, all modems and cards are upgradeable, enabling the user to easily adapt and expand the system in response to growth in the corporate network.

Secondary Controller (Optional)

In multiple chassis systems, a secondary controller card in each slave chassis provides an LED display of EIA-232 signals and acts as an interchassis communications driver.
