AGREEMENT 1-2354 Exhibit A -' .--- A derailed description of the communication system is found in the Rail System Specifications Report prepared as part of Conceptual Engineering. The CONSULTANT shall use this as a point of departure for its Preliminary Engineering work. Operations Control Center. The hub of the communications system is the Operations Control Center (OCC), System controllers will be responsible for all facets of the system and shall be able to communicate with passengers at the ftation through the public address system, speak with train operators using the radio system, speak by telephone or radio with maintenance staff throughout the system, interface with the power and signal system through the data system, and view certain areas through the CCTV system. The CONSULTANT will coordinate the needs of all the communication subsystems with the designer team regarding the CMF layout, and equipment space allocations. Fiber Optic Line. It is anticipated the OCC will be tied into the system through a single-mode fiber optic backbone cable nmning the entire length of the system with cable breakouts at e<\cp station's communications building, separately located traction power substations, and all other locations needing a direct voice, data, or video connection with the OCC. The CONSULTANT will specify a backbone set of conduits mnning the length of the system with capacity greater than that required for The CenterLine's fiber optic cable needs, This greater capacity is for the pulling of future cables, Public Address System. This system will have both loudspeakers and variable message signs and allow system controllers at the OCC or at the station itself to notify patrons system wide, at a prescribed set of stations, or at individual stations of system delays, emergencies, etc., while conforming to ADA requirements. The pANMS system will be located near the ticket vending machines, the principal platform waiting area, in elevators and near escalators (if present) , GPS-based Train Location System, This system will conform with the existing GPS-based passenger communication system used on The AUTHORITY's bus fleet. Each light rail cab car will have a unit capable of receiving GPS signals and converting them to a geographic location, The unit will automatically send this location to a central computer over the train's datil radio system, The central computer will compare the trains location with its schedule, determine its arrival time at the next several stations, and then send the appropriate message automatically through the fiber optic system to the station. This is done continually for each revenue train. Radio System, The radio system will be the primary means of communicating throughout the system, As noted in the Rail Systems Specifications Report of the Conceptual Engineering phase, it is expected that the radio system will be a tnmked radio system or an equivalent technology possibly leased from an existing system, The CONSULTANT will evaluate alternative approaches including a "build-your-own" system, leasing time or frequencies from a private owner, and leasing time or frequencies from a governmental agency, Once an optimal approach is identified and approved, the CONSULTANT will complete the specification of all radio equipment to the 30% design level including the detailed listing of all components. Telephone System. The CONSULTANT will coordinate with The AUTHORITY's Information System's group on types of phones used in The CenterLine Project: local phone lines, 45 CD ,"1
