Nortel Networks announced that John Roth, vice chairman and chief executive, would resume his role as president, following the resignation of Dave House.
House, who was formerly chief executive of Bay Networks, has left the company a year after Bay was acquired by the Canadian giant. At the same time, Nortel said that it had combined its wireless and fixed wire product units to provide converged services for telecoms operators.
Roth said: "Service providers are redefining their business as voice and data, and wireline and wireless services converge. We established first mover advantage with them in the transition from circuit to packet technologies. Now we're doing the same as the worlds of wireless and wireline come together."
