Tekelec reported another decline in quarterly revenue this morning, but its financial results exceeded expectations of Wall Street analysts.

The Morrisville company makes software and other telecommunications technology that helps move data and video over high-speed and wireless networks.

Tekelec reshuffled its top management and slashed jobs this year as it shifts to focus on faster-growing parts of its business. It's counting on increasing demand for products tied to next-generation wireless networks.

In May, the company laid off about 50 people at its Morrisville headquarters as part of a broader restructuring to cut costs. Tekelec employs about 1,250 people worldwide, including about 625 in the Triangle.

Second-quarter revenue was $96.8 million, down 12 percent from a year earlier. Excluding some charges, Tekelec's net income was $5.8 million, or 8 cents a share.

Tekelec has promoted a former Lucent Technologies executive as its new CEO.

Ron de Lange joined the Morrisville-based telecommunications technology company in 2005 and has been "the primary architect of the company's product strategy." He replaces interim CEO Krish Prabhu, who took the job in January after Frank Plastina abruptly resigned after 5 years as CEO.

De Lange, 52, takes over as Tekelec goes through a key transition. The company, which makes software and other technology used by mobile-phone carriers, has seen sales slow and is shifting its focus to the next generation of wireless networks that carry more data and video.
