Atlanta, Georgia. World Congress Center, (June 4, 2001) - ZNYX Networks, a leading global provider of High Availability networking and CarrierClass™ telecommunication products, today announced the first CompactPCI® embedded Ethernet switch designed to support the upcoming PICMG 2.16 specification for packet-switched backplanes (CPSB).

ZNYX Networks' ZX4300P is the first Layer 2 Ethernet switch to seamlessly support operation in both standard CompactPCI chassis and the fabric slots of chassis designed to support the upcoming PICMG 2.16 CPSB specification. Several rear transition modules are available to support 5 through 24 10/100 egress ports, depending upon the chassis architecture.

"The ZX4300P offers OEMs and system integrators uncommon flexibility in architecting current and future system solutions," said Connie Austin, President/CEO ZNYX Networks. This compliments our existing state-of-the-art OpenArchitect switching application platform and provides a powerful design environment for building NEBS-compliant, next-generation solutions tailored to an application profile."

Other features of the ZX4300P include non-blocking line-rate switching performance, HotSwap(TM) capabilities, 802.3x and back-pressure flow control. The switch integrates easily with any host operating system, and supports Intel x86, Sun SPARC, and Motorola PowerPC host CPUs.

"We timed the ZX4300P's introduction to support our early-access backplane technology partners," said Alan Deikman, chief technology officer of ZNYX Networks. "The demand for high-density and low cost is best satisfied with a combination of CPSB and the ZX4300P. Customers now have a switch they can use to accelerate their development of CPSB products for earlier deployment."

The first public preview of ZX4300P will be at SuperComm 2001, June 5-7, Atlanta, Georgia World Congress Center, Booth 402D.

General availability of the ZX4300P will be in September at a suggested list price of $1995 for the base CompactPCI switch. Early access pricing and deliveries will be available through sales@znyx.com to promote our technology partners' development efforts.
