70 -- TACTICAL DATA NETWORK (TDN) AND DIGITAL TECHNICAL CONTROL (DTC) SOL M67854-98-R-2089 DUE 091598 POC Mr. Stephen Riffe, Contracting Officer, (703) 784-5822 Ext. 228, Fax 5826 WEB: MARCORSYSCOM WEB PAGE, http://www.marcorsyscom.usmc.mil/mcscctq/. E-MAIL: Contracting Officer, riffes@quantico.usmc.mil. The Marine Corps Systems Command has a requirement for a combined planned procurement of two major Marine Corps Communications Electronics Systems; the Tactical Data Network (TDN) and the Digital Technical Control (DTC). Both Programs are currently in the Engineering and Manufacturing Development (EMD) phase and have completed fabrication of prototypes. A milestone III Production decision is anticipated in April 1998. The TDN augments existing Marine Air Ground Task Force (MAGTF) communications infrastructure to provide the commander an integrated data network, forming the communications backbone for MAGTF tactical data systems and Defense Message System (DMS). The TDN consists of a network of GATEWAYS and SERVERS interconnected with one another and their subscribers via a combination of common user long-haul transmission systems, local area networks, single channel radios, and the switched telephone system. This network provides its subscribers with basic data transfer and switching services; accessto strategic, supporting establishment, joint, and other service component tactical data networks; network management capabilities; and value-added services such as message handling, directory services, file sharing, and terminal emulation support. A GATEWAY is envisioned to consist of computers, routers, LAN hubs, MODEMS for access to the switched telephone network, link encryption devices, multilevel security guards, patch panels, diagnostic equipment, and uninterruptable power supplies permanently mounted in a shelter for transport on a heavy-variant HMMWV. A SERVER is envisioned to consist of a computer, router, LAN hubs and cabling, radio net interface units, link encryption devices, patch panel, and uninterruptable power supply mounted in three transit cases, each of which can be two-man carry. The planned acquisition quantities of TDN Gateways and Servers are as follows: 13 Gateways, 288 Servers, and 14 Top Secret Servers firm with options for 180 Gateways and 159 Servers. In addition there are twopre-planned upgrades scheduled for the TDN program. These Block upgrades will incorporate the additional functionalities of Top Secret (TS) DMS messaging and Multi-Level Security (MLS) products as available in Block II; and Asynchronous Transfer Mode (ATM), Video Teleconferencing (VTC), IP Fax Capability and a Wireless LAN capability in Block III. The Digital Technical Control (DTC) will provide a deployable, digital technical control capability for communications support organizations organic to a Marine Air Ground Task Force (MAGTF). The DTC facilitates the installation, operation, restoration, and management of individual circuits and digital trunks. It provides the primary interface between subscriber systems/networks within a local area and long-haul multichannel transmission systems. It can add, drop and insert digital circuits into multiplexed digital groups; provide a source of stable timing to connected equipment; condition analog circuits; and perform analog/digital, 2-wire/4-wire, and signaling conversions. The DTC contains the monitoring, testing, and patching equipment required by technical controllers to monitor, troubleshoot and restore faulty circuits and trunks. The DTC will be in an S280 shelter for transport on a 5-ton truck. There is a planned upgrade of the DTC to incorporate Asynchronous Transfer Mode in FY 00/01. The planned acquisition quantities of Digital Technical Control facilities are as follows: 10 DTCs firm with options for an additional 20 systems. The solicitation is open to public entities under the Authority of 10 USC 4532 and 10 USC 2208(j). Accordingly, the following public entity is available as a potential source under the contract to be awarded under this solicitation: Tobyhanna Army Depot, Business Management Directorate, Attn: SIOTY-BU (Mr. John Lesniak), 11 Hap Arnold Boulevard, Tobyhanna, PA 18466-5051.
