Overview An SCS consists of an open architecture, standardized media and layout, standard connection interfaces, adherence to national and international standards, and total system design and installation. Other than the structured cabling system, voice, data, video, and building management systems (BMS) have nothing in common except similar transmission characteristics (analog or digital data signals) and delivery methods (conduit, cable tray, raceway, etc.) that support and protect the cabling investment. This tutorial discusses the elements of a structured cabling system and the operational advantages such an approach may enable. Topics 1. Introduction 2. The Foundation for Systems Integration 3.

Introduction Providing an internationally standardized SCS and consolidating cable-delivery methods for all the systems can reduce initial construction costs for the cabling infrastructure of a modern intelligent building by up to 30 percent. The actual level of savings achieved depends upon the configuration and geographical pricing for material and labor. This also gives the structure an inherent ability to respond quickly and cost-effectively to the changing needs of tenants, which impacts the cost to occupy the space. In some cases, additional construction expenditures for the SCS or BMS, such as devices to optimize the use of power consumption, may be necessary to reduce
