Dilithium Sells Test Tools Product Line to Ixia

Petaluma – January 24, 2006 – Dilithium, the leading supplier of 3G multimedia solutions, announced today that it has sold its test tools product line to Ixia, a leading global provider of voice and IP network testing solutions.

“Our test products have become the leading test solutions for 3G 324M network operators, OEMs, and terminal manufacturers around the world,” said Paul Zuber, Chief Executive Officer of Dilithium. “However, we have decided to focus all of our efforts on core infrastructure and related businesses such as Multimedia Gateways, which enable video and multimedia solutions across 3G and broadband networks. This business is growing rapidly and we believe it would be very challenging to continue to maintain global leadership in both the test tools and the infrastructure businesses.  Ixia is the leader in measurement solutions for IP networks and the acquisition of DNA and related test products will allow them to further expand their business into mobile networks. Dilithium and Ixia are both committed to ensuring business continuity and we are confident of Ixia serving our existing customers well into the future.”

“The market for mobile video is fast expanding with the introduction of innovative 3G product offerings by wireless carriers and content providers,” said Cliff Hannel, Vice President Acquisitions and Strategy for Ixia.  “This is a new high growth test market for Ixia that would extend our wireless offerings.  The DNA test solution can be used in conjunction with Ixia’s IxLoad and IxVoice products to test a wide array of IP and circuit switched data, voice and signaling infrastructures.”
