Network management training for tactical systems

The Mobile Subscriber Equipment (MSE) provided by GTE is an Army tactical communication system providing battlefield voice and data communications. MSE consists of a number of node center switches, large and small extension node switches, line of sight radio equipment to connect fixed assets, and mobile subscriber terminals. The core element providing net management of MSE is the System Control Center (SCC). The SCC provides all the operational orders to the managed elements and in response expects reports from the managed elements. Orders include such items as COMSEC commands, frequency plans, and trunk group parameters. It is planned that the SCC will be replaced by the Network Management Tool (NMT), which will provide increased capability, more flexibility, and enhanced ease of operation. Adequate training in the use of the NMT will be crucial to the success of the mission. Operators must have sufficient background and understanding of all the aspects of the NMT to ensure the managed units receive timely and accurate information. Also critical is the timely response to the managed units requests for service. In preparation for the introduction of the NMT into MSE, GTE has designed the Communication Network Simulation (CNS) system to provide the operator with simulated tactical situations requiring the exectution of: a sequence of tasks. This training will be accomplished through the use of NMT software integrated with a simulation of the managed units, responding in accord with predefined scenarios. The CNS system will be an in-building simulation of the tactical network. Operators must configure the system, respond to messages, and take appropriate action to emergency situations. Operators work in conjunction with trained instructors. The CNS will provide many operator training stations in parallel and thus will be a cost-effective method for NMT training.
