As one of its first major purchases after the 1982 Breakup of the Bell System, AT&T purchased the company for $250 million in 1989. The company grew to become a major supplier in the digital subscriber line (DSL) industry as that expanded. When AT&T spun off Lucent in 1996, Paradyne moved to the new company. Lucent quickly sold Paradyne to Texas Pacific Group (TPG Capital) for $175 million where it became Paradyne Networks.^[1] The company changed hands several times since then and has been owned by DZS since 2005.
