Architecture for the Converged Public Network

Catena Networks today announced that Bob Machlin, former Vice President of Marketing for Cascade Communications, and more recently, Vice President of Marketing for Ascend Communications, joined as President and Chief Executive Officer.

At Ascend Communications, Machlin helped the company become the worldwide leader in Remote Access, Frame Relay and ATM wide area networking (WAN) solutions for service providers globally. As a key member of the executive management team, he helped grow revenues from $1.2 billion to over $2.4 billion and the company's market value from $4 billion to $24 billion at the time of the Lucent acquisition - the largest telecom equipment merger in history.
