Internetworking set another record level with 33% revenue growth compared to third quarter 2007, and Optical Access achieved a record level with 21% growth. This combined with a strong performance by our HDSL products led to our 11% revenue increase compared to third quarter 2007. While the industry is facing uncertainty in the near term, we believe our strong operating metrics combined with the long-term opportunities in our growth areas place us in a solid position.”

The Company also reported that the provision for income taxes in the third quarter of 2008 continued to be unusually high due to delays in federal legislation required to extend research tax credits for the 2008 year. This legislation was finally enacted in the fourth quarter and will apply retroactively for the 2008 year.
