JTNC Frequently Asked Questions   What is the Joint Tactical Networking Center? As part of the Department of Defense (DoD), the Joint Tactical Networking Center (JTNC) supports the Department’s goal of rapid identification, characterization, procurement, fielding and sustainment of modular, innovative tactical communications products that ensure secure, interoperable, and resilient Command, Control, Communications, Computer, Intelligence, Surveillance, and Reconnaissance (C4ISR) capabilities​.  The JTNC concurrently supports the Under Secretary of Defense for Acquisition and Sustainment (A&S), DoD Chief Information Officer (DoD CIO), and Service initiatives by providing technical expertise for waveform exportability and to facilitate standardization of key waveform interfaces.  The intent is to minimize duplication of waveform developments, increase wireless communications software reuse, promote effective information sharing, and integrate command and control (C2) capabilities. What authority establishes the JTNC? ​The Joint Tactical Networking Center is a Joint organization chartered in January 2014 and revalidated in March of 2016 by the Department of Defense and falls under the governance and oversight of USD(A&S), DoD CIO, and the Army Acquisition Executive (AAE).  The AAE has further delegated JTNC executive oversight to Program Executive Office Command Control Communications-Tactical (PEO C3T). ​What value does the JTNC provide? ​ The JTNC operates a cyber-hardened DoD-wide Information Repository (IR) that provides software code and relevant documentation for reuse based on legal agreements between government and software developers.  The JTNC performs technical analyses of candidate waveform information repository products that result in preliminary characterization of these products as to whether they meet DoD standards and policies for interoperable and secure joint tactical networking.  The JTNC provides a validated open architecture framework that identifies standard non-proprietary interfaces that separate the waveform/network manager software from the radio set, permitting common waveforms and network managers to be deployed across multiple radio sets and vendors.  Additionally, the JTNC supports the various DoD agencies overseeing the protection of critical technologies of wireless communications exported under commercial and/or Foreign Military Sales and licenses ​What is the JTNC responsible for? - Operation and maintenance of a common cyber-hardened DoD Information Repository (IR).  - Sustainment and evolution of the Software Communications Architecture (SCA), Application Program Interfaces (API), and wireless communications standards. - Conducting technical analyses of waveforms, software, and associated artifacts, and recommending designation of such products as exportable and compliant or certified with regard to DoD applicable policies.  How is the JTNC organized? ​The JTNC consists of two primary functional directorate that perform five core functions in support of the DoD: Information Repository, Technical Analysis, Open Systems Architecture Standards, Exportability Analysis and Licensing​ Review, and Technical Advisory What has the DoD Information Repository enabled?​ ​The DoD IR provides the security, configuration management, and software distribution of DoD waveforms and associated artifacts.  As a central waveform distribution center within the DoD, the DoD IR is responsible for the cyber protection and storage of the waveform artifacts.  It provides a consistent cataloging of the waveform software to assist software developers in the reuse of the government-managed software. The DoD IR Directorate operates and maintains an online interface accessible from the Internet for DoD IR registered users. The site is common access card (CAC) protected and requires users to register with the DoD IR to upload or download waveforms.
