Operational Requirements for the Remote Maintenance Monitoring System (RMMS).

This operational requirements document was prepared for use in support of the development and implementation of a Remote Maintenance Monitoring System RMMS for the National Airspace System NAS. Fundamental concepts of RMMS operation and the system description have been previously developed by the Airway Facilities Service AAF. The information generated by the Remote Monitoring Subsystem RMS at the equipment site shall be directly available to the responsible maintenance personnel at their work center. Initially, a Maintenance Processor Subsystem MPS will be installed at the ARTCC where communications lines with enroute equipment and major airports presently exist. Future MPSs shall be located at sector offices, or major workcenters. The MPS shall monitor the status of all equipment for a specific geographical area and shall automatically notify the monitoring facilities of the equipment alarms. The monitoring facility shall be alerted of an alarm by both visual and aural signals describing where alarm has occurred, the type of alarm, and which equipment is alarming. The MPS shall serve as the primary collection point, processor, and distribution center for all RMM and Maintenance Management System MMS data. The RMMS will remote many routine maintenance functions currently performed at the remote equipment sites and will permit them to be accomplished at any suitably equipped work center.
