Comms Switching and Control Sys
Abstract
(U) Tactical Voice Switching System (TVSS): The TVSS is a modular Integrated Services Digital Network (ISDN) circuit switch capable system that provides Voice Over Internet Protocol telecommunications, multiplexing, transmission encryption, and group modem capabilities in one system for tactical telephony voice communications. TVSS is reaching end of life and is planned to be removed from the fleet inventory by the end of FY21. (U) Combat Data Network (CDN), formerly Data Distribution System - Modular (DDS-M): The CDN provides the commander a modular, integrated, and interoperable Internet Protocol (IP) - based Local Area Network (LAN) and Wide Area Network (WAN) capability that forms the data communications backbone to tactical organizations within a Marine Air-Ground Task Force (MAGTF). The CDN provides an extension of the Defense Information System Network (DISN), Secret Internet Protocol Router Network (SIPRNet), Sensitive But Unclassified (SBU), Non-secure Internet Protocol Router Network (NIPRNet) as well as a coalition networking. The CDN provides Marine Corps maneuver elements with a modular and scalable IP data transport capability by providing computers, servers, routers, data switches, cabling, multiple connections to various tactical transmission devices, contains integral In-line Network Encryption (INE) device supporting IP Security (IPSec), and Virtual Private Networking (VPN). CDN is currently designated as the Common Hosting Environment (CHE) for tactical networking. CHE will consolidate like capabilities from various programs of record, primarily server capacity and network access switching, under a single program of record. CHE will simplify the equipment string and will help reduce the overall Size, Weight, and Power (SWaP) requirements for the MAGTF. In FY21 the Combat Operations Center (COC) requirements PE 0206313 Project 2275 transitions into the Combat Data Network (CDN) program under the title Common Hosting Environment (CHE).
