Long Haul Communications

Abstract

The Defense Information System Network (DISN) is the Department of Defense (DoD) consolidated worldwide telecommunications capability providing secure, end-to-end information transport for DoD operations, providing the warfighters and the Combatant Commanders (COCOMs) with a robust Command, Control, Communications, Computers, and Intelligence (C4I) infrastructure to support DoD mission and business requirements. DISN Operational Support Systems: The DISN Operational Support Systems (OSS) provides the Information Technology (IT) components that instrument and automate the Operations, Administration, Maintenance, and Provisioning (OAM&P) functions for the DISN. OSS funds the engineering and integration efforts needed to integrate the management of network components into a single DISN-wide view for DISN managers and operators. This facilitates more responsiveness to users' provisioning requirements, quicker detection of and response to problems and outages, network tuning for more efficiency and performance, and more cost-effective management. As the DISN undergoes continuous technology refreshment, management capabilities of new components must be integrated into the OSS. The OSS incorporates a Service Oriented Architecture and is adhering to industry standards and best practices. DISA works actively with the Military Services to ensure that the DISN OSS and the Services' tactical networks share information and provide an end-to-end view for network operators. DISN Systems Engineering Support: Funding supports systems engineering for technology refreshment of the Defense Red Switch Network (DRSN). This includes,(a) complete development of a modified version of the DSS-2A switch as a replacement for large capacity SDS-1 Red Switches that are at End-of-Life (EOL), and (b) to develop replacements for components and peripherals of the Red Switch to keep the entire DRSN system sustainable. The products developed and accredited as a result of this effort will be purchased and fielded by the Military Services and other authorized users of the network. *Distributed Tactical Communications System (DTCS): The **DTCS is a new variation of the Iridium Satellite Phone commercial offering used by the warfighter under the Enhanced Mobile Satellite Service (EMSS). The variation improves Iridium’s capability to network and sub-network users to improve performance, reduce end-to-end latency and improve data handling to the handset. New handsets are required with software modifications to allow Iridium satellites to “relay” information between the satellites. A separate Network Management capability is required since the new service cannot leverage current the standard commercial Iridium Network Manager. Funding provides engineering, development and testing resources to transition the Naval Surface Weapons Center’s (NSWC) Technology Prototype to a fully fielded operational capability. NEADN/PNVC: The National Emergency Action Decision Network (NEADN) provides system engineering, development and testing of the Presidential and National Voice Conferencing (PNVC) equipment for senior leaders. The PNVC system provides a military satellite-based, world-wide, survivable, secure, and near toll-quality voice conferencing capability for the President, Secretary of Defense, Chairman, Joint Chiefs of Staff, and other senior national/military leaders. By implementing new technology capabilities (e.g. Ethernet-Framing and higher data rate), this project provides improved performance to the survivable voice conferencing capability. Specifically, the project funding supports the acquisition activities for the PNVC baseband equipment, including critical and essential engineering required to develop new vocoder and cryptographic, and audio-summing equipment. PNVC baseband development and production schedule is synchronized with the fielding of military Advanced Extremely High Frequency (AEHF) satellite communications (SATCOM) terminals. If funding is not provided, the DISN will not be able to support the new and changing missions of the warfighter, technology refreshment efforts, and changing technology. Lack of sufficient funding will significantly impact the implementation of an enhanced, survivable voice conferencing capability to the President and other decision makers.

Document Details

• Document Type: R2 Budgetary Justification
• Publication Date: Oct 01, 2011
• Source ID: 0303126K_7_0400_PB_2011
• Change Summary Explanation: The FY 2009 reduction of -$0.377 million due to below budgeted execution of DISN systems Engineering Support on the DSS-2A Switch. The FY 2010 reduction of -$0.249 million is a result of Congressional taxes for FFRDC related costs and Economic Assumptions. The DoD did not estimate FY 2011 cost when the FY 2010 President’s Budget was prepared.
