Network bridge that moves Link-11 shipboard data over Ethernet introduced by Sabtech

Posted by John Keller

YORBA LINDA, Calif., 14 June 2013. Sabtech Industries in Yorba Linda, Calif., is introducing the PowerNet ATDS Bridge system to help aerospace and defense communications applications extend Airborne Tactical Data Systems (ATDS) serial (MILSTD-188-203-1A, Appendix D2) data communications over a military network.

ATDS is for equipment that supports Tactical Digital Information Link-A (TADIL-A) or its NATO designation, Link-11. The PowerNet Bridge provides a transparent hardware and protocol conversion that enables Data Terminal Set (DTS), Tactical Data System (TDS), and cryptographic equipment to communicate over a network without modification to either end.

Moving the ATDS link to a network architecture eliminates cable length limitations and enables redundant paths through the network fabric to improve the survivability of the interface.

The PowerNet Bridge system consists of two PowerNet servers, one connected to the legacy ATDS device at each end of the interface. The servers connect together over a dedicated or shared Ethernet network.

In operation, the servers convert the ATDS channel protocol into Ethernet packets that convert back to ATDS at the distant end. The PowerNet server typically is mounted near the legacy equipment to make the ATDS cable run as short as possible.

Designed with redundant capability, the PowerNet Bridge system is equipped with dual Ethernet ports to increase reliability. When configured to operate in dual port mode, if one interface or network path is not available, operation continues without delay or interruption on the surviving path.

Several form factors are available including, a 6U VME board, a 19-inch rackmount system, or an enclosed ruggedized version. PowerNet ATDS is also available as a standalone system.
