ALARM SYSTEM CONCEPT DESCRIPTION General Scope: The general intent and scope of this concept description of the alarm and control system is to generate an acceptable overview of the networking of the alarm system. This is required in order to gain a greater understanding of the methods used to deriver transmit and receive alarm indications from any single facility' The basis of this description will be to allow personnel outside the company to develop an overview understanding of alarm reporting and control response. Events: This concept description will cover the major areas of Alarms, Transmission, Reception and Distribution. The description will address the methods used and results expected. Alarms: MCI Telecommunications maintains an extensive network of communication facilities covering Satellite, Microwave Radio, Fiber Optic Cable and Switching Systems throughout the United States. In order to operate and maintain this communications system it is necessary to receive an extensive number of alarms covering all the possible conditions that any single facility can generate. Alarms which are generated may be detected either using a voltage or grounding method. The method used will be determined by the type of sensing unit that will produce the alarm required. If any type of event can be detected by a sensor that can be converted into an alarm and transmitted to a central point located anywhere in the United States' Once an alarm has been generated and detected on any facility it is then routed to a central processing unit (DataLoc-10) which accepts all the alarms generated at that facility. The central processing unit then compiles all alarms generated at the facility into a single data stream which is formatted and designed to be transmitted across the required transmission system path' Transmission: The transmission system path varies according to the type of equipment used by MCI. Even though the equipment type may change all of the basic interface points remain the same from facility to facility. This is required in order to ensure that all facilities will be able to report to a central location regardless to the equipment used to relay the information. The transmission system excepts the alarm data which was formatted by the DataLoc-10 and process this information and then transmits the data to the nearest Junction' The Junction accepts the incoming alarm data stream and then combines the data with all other alarm data streams reporting through that Junction facility. The Junction then transmits all the alarm data streams to the central reception facility which reprocess the alarm information. Reception:
