Pomona, Calif., and Fremont, Calif. – February 22, 2002 – Rockwell Collins, Inc. (NYSE:COL), a world leader in the design, production and support of communications and aviation electronics solutions and ZNYX Networks, a leading global provider of high-availability embedded Ethernet solutions, today announced that ZNYX Networks’ embedded switch design and OpenArchitect™ software have been exclusively selected and approved by Rockwell Collins for integration with its new eTES™ commercial in-flight entertainment systems.

“To stay competitive, airlines need more to differentiate themselves than offering extra leg room,” says Connie Austin, CEO of ZNYX Networks. “Our high availability embedded Ethernet technology is adding value to Rockwell Collins’ avionics solutions by enabling sophisticated airborne services.” Applications supported by the e-TES system include movies-on-demand and in-flight Internet services.

ZNYX Networks’ embedded switch design and OpenArchitect software provide sophisticated data switching services for the new Rockwell Collins eTES in-flight entertainment systems, scheduled to ship in mid-2002. These systems offer airlines and their passengers with unprecedented and robust communications and entertainment services, such as in-flight Internet connectivity, e-mail access, on-demand audio and video to every seat in a configured aircraft.

“Providing passengers with more than 80 full-length, feature films or in-flight Web browsing requires a networking solution capable of unparalleled performance,” said Dan Bergen, director of product marketing for Rockwell Collins Passenger Systems. “Given the demanding environment of aircraft avionics, Rockwell Collins is pleased to use the ZNYX switch design and OpenArchitect software in our eTES systems.”

Rockwell Collins has licensed the hardware design to the ZNYX Networks ZX4500 embedded switch. This design includes a silicon-based switching fabric, microprocessor chip, memory chips and network interface chips. The design provides 24 10/100 Mbit Ethernet ports and dual 1 gigabit Ethernet port. Rockwell Collins has configured the form factor of the design to fit its custom airborne hardware.

Rockwell Collins has also licensed the Ethernet routing software platform, OpenArchitect for Managed Switches. OpenArchitect, running on the microprocessor, provides extensive routing protocols such as Spanning tree, VLAN, OSPF, VRRP and QoS. These protocols support the creation of policies for managing packet flow between components within the eTES system and to passengers over the airborne network. OpenArchitect interfaces with the silicon-based switching fabric to execute packet routing at full line speeds – up to 6.6 million packets per second.

Rockwell Collins is manufacturing the switch hardware for the eTES and installing OpenArchitect on each switch. ZNYX Networks provides a binary master of the OpenArchitect software platform and develops future releases.
