Enterasys Adds Tenor 's Technology, Exec

Telecom equipment maker Enterasys Networks has bought the technology assets of multiservice switch maker Tenor Networks for an undisclosed sum.

Tenor folded in February after using up $123 million in venture capital over four years. Its last round came in August 2000.

The deal advances "our current core routing development path, and speed time to market for adding high-performance IP/MPLS capabilities to our portfolio of enterprise routers," Enterasys CEO William K. O'Brien said.

In addition, Enterasys hired Tenor cofounder Leon K. Woo as executive vice president of engineering. He will lead the company's research and development from its new headquarters in Andover, Mass.

Previously, Woo was vice president of research and development at 3Com's switching division. The establishment of the 3Com Switching Division resulted from the acquisition of Synernetics in 1994, a company Woo co-founded.

Tom Bunce, Enterasys' former exceutive vice president of engineering, will move into a "customer advocacy role."

Woo will be joined by other Tenor engineers, including Robert Ryan, former Vice president of research and development and co-founder of Tenor, who will head Enterasys' advanced core routing group.

Tenor was based in Acton, Mass., and was among a handful of area networking startups whose technology was well regarded but ultimately failed when the telecom market slumped. Others included Cereva Networks and Gotham Networks.
