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.
The HDMS includes several components: a chassis for rack mounting up to 32 modems per chassis to conserve space and energy, an Intelligent Network Controller (TM) to manage the modems as one integrated unit and the modems themselves. These modems include the HD/FAST (TM) dual modem card featuring 28.8 Kbs and the HD/4232bis dual modem card featuring 14.4 Kbs. Network managers can select the modem standards best suited to their specific network requirements, such as V.34 with MNP 10 Adverse Channel Protocol. Users even have the option of mixing and matching various modems and security types simultaneously.
HDMS plus Chassis (TM)
Each HDMS plus chassis can accommodate 32 High Density (HD) modems and the Intelligent Network Controller (INC). Up to eight chassis can be daisy chained, allowing 254 modems to be controlled by a single INC. A V.24/EIA-232 interface is provided for each modem. The HD/FAST modem is also available with a V.35 interface (optional) for high-speed applications.
