BICSI
Since the official break-up of AT&T in 1984 in the United States, the Building Industry Consulting Service International (BICSI) assumed the role that AT&T's free service, BICS, fulfilled in helping with the development and design for information technology systems (ITS) such as the ANSI/EIA/TIA 568B structured cabling system standard.
Headquartered in Tampa, Florida, the organization has membership in nearly 100 countries. It certifies cable installers and designers who specialize in complex voice/data cable layouts.
