caltrain DESIGN CRITERIA. CHAPTER 6 TRAIN CONTROL COMMUNICATION . CHAPTER 6. TRAIN CONTROL COMMUNICATION . A. GENERAL. The Design Criteria presented in this CHAPTER for mission or operations critical TRAIN CONTROL COMMUNICATION defines the technical requirements used for the development of specifications and the design of the Advanced TRAIN CONTROL System (ATCS) Data Radio COMMUNICATION system, the various telephone interfaces and the Very High Frequency (VHF) Voice Radio COMMUNICATION system. The ATCS Data Radio and the VHF Voice Radio are both independent stand-alone COMMUNICATION systems which are each supported by a caltrain -owned microwave radio network and by various leased telephone subsystems, including T1, 4-Wire (Analog), 4-Wire E&M (Analog), 4-Wire (Digital), 2-Wire (Analog), Frame Relay and DSL for back-haul. The Design Criteria defines the requirements for these COMMUNICATION systems and sub-systems to safely and efficiently fully support the caltrain operations, as well as the requirements to expand these systems in order to support future caltrain COMMUNICATION needs.
