Tham khảo tài liệu 'cabling standard - tia 569-a - technical spec overview', công nghệ thông tin, quản trị mạng phục vụ nhu cầu học tập, nghiên cứu và làm việc hiệu quả | TECH INFO 1/13/05 12:15 PM Page 12 A TECHNICAL INFORMATION P P E ANSI/TIA/EIA-569-A N ANSI/TIA/EIA-569-A Pathways and Spaces D As the complexity of voice and data telecommunications has increased, I standards have been established to ensure the operability, flexibility, manageability and longevity of these critical commercial support systems. X Telecommunications now encompasses voice, data and video transmission of business information, fire/security, audio, environmental and other intelligent building controls over media that includes fiber optics, specialized copper data cabling, microwave and radiowave. This booklet concisely describes the architectural design elements of cabling pathways and dedicated rooms for telecommunications equipment. A multitenant commercial building has a life expectancy of at least 50 years. Software, hardware and communications gear have far shorter lifespans of one to five years. Moreover, in a multitenant environment, continuous moves, adds and changes are inevitable. It is the purpose of standards to guide design and ease future changes—by planning for the future now. These standards are intended to provide for a generic structured cabling plant, capable of running any voice or data application foreseeable in the next 10 to 15 years.
