Our corporate headquarters and principal administrative, engineering, and manufacturing facilities are located on an 80-acre campus in Cummings Research Park, the nation’s second largest science and technology community. In addition to Huntsville, the company also has engineering facilities in Phoenix, Arizona, Mountain View, California, and Ottawa, Canada. With superb talent and excellent management, the company has steadily grown to a workforce that now approaches 1,700 employees worldwide.

ADTRAN has two distinct operating divisions, CarrierNetworks and Enterprise Networks. The Carrier Networks Division offers products used by service providers to deliver voice and broadband services to a customer’s premises.
