About ADTRAN

[adinserter block="1"]
ADTRAN, Inc. is a provider of telecommunications networking equipment and internetworking products. Its headquarters are in Huntsville, Alabama. The company is ISO 9001 and TL9000 certified. ADTRAN was a NASDAQ-100 Index stock from 1996 to 1998. It was #85 on BusinessWeeks 100 "Hot Growth Companies" list in 2006. ADTRAN was founded by Mark C. Smith and Lonnie McMillian, and began operations in 1986. The AT&T divestiture of the Regional Bell Operating Companies (RBOCs), with restrictions that effectively barred their manufacturing of equipment, created an opportunity for companies such as ADTRAN to supply network equipment, both to the seven RBOCs and the new and independent telephone companies in the United States.
