NWK Network Equip Tech

Network Equipment Technologies, Inc. (NYSE: NWK) today announced the successful completion of Joint Interoperability Test Command (JITC) Interoperability Certification for its VX 900 VoIP Gateway with software release 4.3.5 version 55, for Tactical Network Element (T-NE) and Strategic Network Element (S-NE).

The VX900 is currently used by the Army, Air Force, Marines, Navy, JCSE, SOCOM and other Joint Commands.

In order to be certified by JITC, the VX 900 had to pass both Interoperability (IO) Certification and Information Assurance (IA) Accreditation. These certifications allow the product to be added to the Defense Information Systems Agency's (DISA) Approved Products List.

DISA's JITC certification is required for all voice networking equipment connecting to the U.S. Department of Defense core network. In December 2002 this requirement became law with the signing of Public Law 107-314, PDF SEC 353 (S348/H354).

"NET's products are deployed in many government networks," said Gary Lau, General Manager of NET's Federal Group. "Completion of these certifications, and acceptance on DISA's Approved Products List, assures our clients and government agencies that our communication equipment will perform flawlessly in all their mission critical applications. Obtaining the JITC certifications is not only essential for deployments within the Defense Switched Network, but also for other customers who require secure communications solutions with proven reliability under extreme conditions."
