Westell Technologies, Inc. is an Aurora, Illinois company whose primary business is producing DSL modems for the home and small office. Westell is the last company to manufacture DSL modems in the United States; however, on May 21, 2007, Westell announced plans to outsource manufacturing.
Westell was founded in October 1980 in Willowbrook, Illinois, and initially produced electronic equipment used for signaling and transmission on telephone lines leased to private customers. Beginning in 1992, Westell began developing ADSL products. By the time of its IPO in 1995, Westell was a prominent DSLAM manufacturer. The company moved out of this business in the wake of the stock market downturn of 2002, and now focuses primarily on manufacturing DSL modems.
Westell's other businesses include Network Service Access (NSA) products and conferencing services through a subsidiary, ConferencePlus.
