One of the country’s major cell phone service providers had an advertising campaign that portrayed a technician in various remote locations checking the signal by asking, “Can you hear me now?” While dropped calls and weak signals are annoying, most of the time the technology works. How is it possible that we are able to make a telephone call, whether from a cell phone, pay phone, or our home, to almost anywhere in the world? In a word - standards. Telecommunications carriers, service providers, and equipment manufacturers all use standards to ensure reliable transmission and interoperability between equipment.
Accredited standard developers in the area of telecommunications are the Telecommunications Industry Association (TIA) and the Alliance for Telecommunications Industry Solutions (ATIS).
TIA is responsible for developing standards for telecommunications equipment that connects to the U.S. telecommunications network.
ATIS is involved in the U.S. national telecommunications standards for the network to which the equipment attaches. Other groups within ATIS are responsible for developing standards, guidelines and operating procedures that make the interoperability of existing and emerging telecommunications products and services possible.
