Corporate history[edit]

Jean-Claude Asscher[edit]

In 1961, Jean-Claude Asscher founded Tekelec-Airtronic, SA, a French electronics company with emphasis on the aviation industry. Jean-Claude Asscher serves as the president and chairman of the board of directors of Tekelec-Airtronic, SA.

In 1971, Jean-Claude Asscher founded Tekelec, Inc. as a North American company specializing in telecommunications products, such as telecommunications test equipment initially. Tekelec was initially financed by proceeds earned by Jean-Claude Asscher through Tekelec-Airtronic.

For many years, Jean-Claude Asscher was president, CEO, and chairman of the board of directors of both Tekelec-Airtronic and Tekelec. In recent years Jean-Claude Asscher has served as only chairman of Tekelec's board of directors while continuing to be the president of Tekelec-Airtronic's board of directors as well as its chairman.[citation needed]

Philip Black[edit]

Asscher found Philip Black, in the early 1980s, who was tasked with re-creating the U.S Tekelec company so that could successfully sell Tekelec Airtronic products in the U.S., or create their own testing products. Philip Black assembled a core crew of people, including Anders Hultin, Bob Hess, Adrian Warren, Peter Rifkin, Annette Michaelson, Michael Leigh, Joseph Noble, Jerome Nathan and Stephan Greppi, among others. This team created, marketed and sold the protocol simulator analyzers, named Chameleon and Chameleon II which fueled the sales of Tekelec for over 10 years. Tekelec successfully competed with two pre-existing competitors, Atlantic Research and Idacom, to become the dominant player in this specific type of test equipment. The company went public in the mid-1980s. Tekelec later transitioned to operating equipment in the form of Signalling System 7 products, under the initial lead of Peter Vicars, who followed Philip Black as CEO.

Peter N Vicars[edit]

Peter N Vicars joined Tekelec and served as its President and Chief Executive Officer from July 1987 until January 1994. During this tenure revenues increased from $13M to $58M while maintain six years of double digit profitability within its core business of testing solutions which represented 85% of corporate revenues. Vicars successfully acquired and integrated a leading SS7 company(Protocol Technologies) to strengthen Tekelec's market position in cellular and switching technology. Based on that acquisition Vicars guided the entry into a new market for the corporation with a breakthrough approach, the Eagle platform and revenues grew to $12M over the first year of product shipments. Vicars is also credited for implementing an expense reduction program, due to the switching product startup development and initial market entry costs, which returned the corporation to profitability.

Franco (Frank) Plastina[edit]

Franco Plastina joined Tekelec and served as President and Chief Executive Officer and as a director in February, 2006. Plastina stepped down from his position as President and CEO of Tekelec in January 2011 following poor results where sales of the main product line, Eagle, dropped off much more sharply than expected, before replacement products (such as policy) became fully available. Krish Prabhu, a member of the Board of Directors, was appointed Interim President and CEO.

Ronald J. de Lange[edit]

Ronald J. de Lange joined Tekelec in July 2005 and most recently served as executive vice president Global Business Solutions before being promoted to CEO in May 2011. He is a 24-year veteran of Lucent Technologies, where he held a number of leadership roles.
