Quintum Technologies announced that the US Navy has operationally demonstrated its Tenor VoIP switching platform as an effective solution for implementing highly efficient secure ship-to-shore voice communications. During the Navy's Trident Warrior '04 (TW04) exercise in October 2004, the Automated Digital Network System (ADNS) demonstrated the Navy's ability to use Quintum's Tenor switches to eliminate outmoded, inefficient time division multiplexing (TDM) voice network connections in favor of the converged transport of both voice and data communications over a more economical common IP-based satellite link.
With the Tenor switching platform, unencrypted ship-to-shore VoIP calls required approximately 8.5 kbps of network bandwidth, versus the 8 kbps to 64 kbps per channel required under TDM. Use of a common network link for voice and data traffic also allowed the Navy to dynamically allocate additional available network bandwidth for data since voice utilization is typically less than 20%, so that data applications can benefit from increased bandwidth over 80% of the time. In addition, the Tenor-enabled VoIP connectivity can be used for secure telephone calls and fax transmission. Quintum provided the Navy with customized software to support its requirements for secure VoIP calls. The Tenor switches successfully supported encrypted STU-III calls over IP at 24 kbps gross bandwidth.
Other benefits of the Tenor platform include the capability to use multiple paths for IP traffic, which improved service availability from 53% to 90%, and consistently high call quality.
Just as important, the implementation did not require the Navy to replace or modify any of its existing phones, PBXs or IP network infrastructure. Quintum Tenor VoIP MultiPath Switches have a unique MultiPath architecture and intelligent call routing capabilities which make them particularly well-suited for integration with existing telephony environments and for simplified implementation on existing IP data networks.
"This pilot project validates VoIP as a transport for ship-to-shore voice and fax communications in general and the Quintum Tenor platform in particular," said Callis Goodrich of SPAWAR Systems Center San Diego, Chief Engineer of the US Navy Automated Digital Network System (ADNS). "Quintum's robust technology and responsive technical support services enabled ADNS to demonstrate how our next-generation network architecture can create the more robust communication environment required to support increasingly complex military operations - while at the same time reducing infrastructure costs."
One of the primary objectives of ADNS is to move the Navy to a fully IP-based transport architecture with differentiated Quality of Service (QoS) for various applications. The demonstration of the Tenors during the TW04 exercises specifically focused on the use of VoIP on a small ship.
"The Navy's testing of Quintum's Tenor solution during its TW04 exercises demonstrates once again the adaptability of our VoIP switching architecture in supporting a full range of communication environments and how easy we make it for organizations of all types to reap the full potential benefits of VoIP," said Chuck Rutledge, Vice President of Marketing for Quintum Technologies. "It is particularly rewarding to see our technology deployed in a way that could substantially benefit US military forces as they perform duties of such a vital nature to our nation and the world."
