TSA Structured Cabling System Guidelines Issue Date: 04/24/181.INTRODUCTIONThis document provides direction for a telecommunications wiring system for TSA spaces or buildings tosupport TSA’s mission and operations. Its purpose is to enable the planning and installation of buildingwiring with minimal advance knowledge of the telecommunications products used.Building wiring represents a significant investment. A variety of wiring plans and media exist in buildingstoday, resulting in an increase in labor costs for move, add and change (MAC) activities. Also, selectivere-wiring is occurring in some locations where the existing media does not provide sufficient bandwidthtransport capabilities.These guidelines are to apply to future installations and renovations of buildings and work areas.The content of this document follows EIA/TIA guidelines. It represents a subset of the appropriateEIA/TIA standards refined to meet specific TSA requirements. All cabling standards contained herein areinstaller independent.1.1ScopeThis content of this document defines guidelines for structured telecommunications wiring within TSAfacilities or buildings. This includes all components from work area connections to local inter-buildingfacilities. Deviation is discouraged, although, designers will review and document if necessary.1.2Structured Cabling SystemsThe specifications contained in this document originate from the recommended use of structured cablingsystems for all communications wiring requirements. These systems are composed of cabling segmentsthat generally correspond to the vertical and horizontal dimensions of buildings and campuses. Byinterconnecting these segments to one another in prescribed ways, complete end-to-end connections existto support the physical wiring needs of various systems. Standards refer to each such segment of cablingas a subsystem.When at all possible, install structured cabling systems as fully as possible in their plant andadministrative buildings. This may lead to a certain degree of pre-wiring at workstations where presentequipment needs are minimal or even nonexistent. Pre-wiring
