ANSI/TIA/EIA-569-A
Design Considerations
1. Purpose of the ANSI/TIA/EIA-569-A Standard
As the complexity of voice and data telecommunications has increased, standards have been established to ensure the operability, flexibility, manageability and longevity of these critical commercial support systems. 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 multi-tenant 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 multi-tenant 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.
