Ruggedized Cisco Catalyst 4948E Data Center-Class Ethernet Switch for Military / Aerospace Introduced by Parvus

High Performance, MIL-STD Qualified DuraNET 4948 Delivers 52-Ports of Cisco IOS Managed Gigabit and 10 Gigabit Network Connectivity

SAN DIEGO, CALIFORNIA, 23 January 2012 (AFCEA WEST Booth #1817) – Eurotech subsidiary Parvus Corporation announces the DuraNET® 4948, a ruggedized version of Cisco Systems’ high performance Catalyst 4948E data center switch with forty-eight (48) downlink and four (4) uplink ports in a hardened 2U chassis qualified to meet MIL-STD-810G environmental and MIL-STD-461F EMI requirements. This powerful, multilayer switch enables demanding military and civil IP networking technology refresh programs to leverage the best that Cisco switching technology has to offer, but in a ruggedized 19” rack mount solution suitable for Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR) applications.

This rugged Commercial-Off-the-Shelf (COTS) product extends the application use of industry-leading Cisco hardware through mechanical enhancement that support deployment of data and multimedia services in wider thermal, shock, vibration, altitude, and humidity conditions than offered by the standard commercial Cisco version. The DuraNET 4948 integrates redundant aircraft-grade power supplies, internal heaters, enhanced heatsinking, and upgraded cooling fans with efficient front-to-back chassis airflow management to reduce data center operating costs.

Suitable for demanding military ground vehicle, aircraft, and maritime installations, the DuraNET 4948 comes equipped with rugged MIL-38999 connector interfaces, bringing out a total of 48 Gigabit Ethernet downlinks, plus three 10 Gigabit Ethernet uplinks (2 Copper/1 Fiber) and a Gigabit Fiber uplink. The unit features Cisco’s full-featured Enterprise Services IOS software image with the advanced Quality of Service (QoS), high availability, security, and manageability that customers expect from Cisco for critical data center architectures, including advanced Layer 3 routing protocol support, 3DES encryption and network management tools.

Parvus to Supply AT&T Government Solutions with Vehicle Interface Computer for U.S. Army OneTESS War Game Simulation System

Parvus’ DuraCOR 810 Processor Platform to be Deployed on Bradley M2/M3A3, Abrams M1A2 SEP and M109A6 SP Paladin Vehicles

SALT LAKE CITY and ORLANDO – August 5, 2008 – Parvus Corporation announced that AT&T Government Solutions, Inc. has contracted with Parvus to supply the Vehicle Interface Control Unit (VICU) for the U.S. Army’s next generation tactical engagement simulation system. Parvus has received an initial order worth approximately $200,000 for 14 pre-production units. Initial operational capabilities for the One Tactical Engagement Simulation System (OneTESS), deployed at Army training centers, are planned for fiscal 2008 for use on Bradley M2/M3A3, Abrams M1A2 SEP and M109A6 SP Paladin Vehicles.

The VICU component of the OneTESS program is based on Parvus’ Commercial-off-the-Shelf (COTS) processor platform, the DuraCOR® 810, integrated with optional MIL-STD-1553 interfaces from Data Device Corporation (DDC). The modular DuraCOR 810 is a rugged open-architecture solution for military/civil Command, Control, Communications, Computer, Intelligence, Surveillance and Reconnaissance (C4ISR) applications. It is designed to survive harsh mobile environmental conditions experienced under MIL-STD-810F, including extreme temperatures, shock/vibration, and ingress, as well as power requirements of MIL-STD-1275 and MIL-STD-704.

The Army Program Executive Office for Simulation, Training and Instrumentation (PEO STRI) previously announced a contract award to AT&T Government Solutions, Inc. for Phases II and III of OneTESS worth approximately $94 million. The Army’s OneTESS has the capability to support up to brigade-level, scaleable to theater-level, training and testing exercises. OneTESS will provide a live combined arm Force-on-Force (FOF) and Force-on-Target (FOT) training that support all Army tactical missions, and crosses all battlefield operating systems at homestation, Maneuver Combat Training Centers, test ranges, and deployed sites. OneTESS is a component of the Army’s interoperable, systems-of-systems, live-virtual-constructive operational architecture, simulating combat realism for live players.
