Founding and early growth The company was founded in 1988. IEEE Spectrum reported that former TRW engineers founded PairGain to develop DSL transceivers and introduced an HDSL system that achieved substantial early market share in business broadband deployments. PairGain completed an initial public offering in 1993.
1999 investigation and internet hoax In 1999, two executives were probed in a criminal investigation. Separately, a fabricated online takeover report in April 1999 temporarily inflated PairGain’s share price. The U.S. Securities and Exchange Commission later filed enforcement action against the individual responsible.
