DESCRIPTION/FUNCTION


The Advanced Narrowband Digital Voice Terminal (ANDVT) Family comprises the AN/USC-43 Tactical Terminal (TACTERM), the KY-99A Miniaturized Terminal (MINTERM), and the KY-100 Airborne Terminal (AIRTERM). These terminals are handled as UNCLASSIFIED controlled cryptographic items (CCIs) when unkeyed; when keyed they assume the classification of the key. The ANDVT family provides joint interoperability between Service components of US command elements and North Atlantic Treaty Organization allies.

ANDVT Family units are primarily used to satisfy tactical secure voice requirements on high frequency (HF), very high frequency (VHF), and ultra high frequency (UHF) satellite and line-of-sight (LOS) communications; UHF Non-Demand Assigned Multiple Access (Non-DAMA) and DAMA; super high frequency (SHF) and extremely high frequency (EHF) satellite communications (SATCOM) including Milstar; UHF Follow-on (UFO)/EHF; and Fleet Satellite EHF Package (FEP). All ANDVTs must have engineering change proposal-060 (ECP-060)/field change -1 (FC-1) incorporated in order to operate over UHF SATCOM.

TACTERM: The TACTERM normal configuration consists of the Basic Terminal Unit (BTU) (CV-3591) and a communications security module (KYV-5), providing half-duplex, secure transmission of voice or data communications in either point-to-point or netted mode. The peripherals include the split remote control units (SRCUs) Z-ANG and Z-ANH, which replaced the existing PARKHILL type IIIA and IIIB. A "Y" cable will allow remote loading of cryptographic variables from the SRCU Z-ANG. The Navy developed the TACTERM in association with the National Security Agency (NSA).

MINTERM: The functions of the MINTERM are similar to those of the TACTERM; however, its updated design includes an improved modular architecture, and it has been reduced in size. The MINTERM is a low-cost, lightweight, low-power, single channel, half-duplex, narrowband/wideband/wireline terminal providing secure voice and data communications with full key distribution and remote rekey capabilities. The MINTERM is certified to secure traffic up to TOP SECRET.

The MINTERM improvements include the following:

  • Concurrent voice and data modes enable the users to connect both data equipment and voice handsets.
  • VINSON (KY-57/58) mode of operation allows interoperability between the MINTERM and the VINSON wideband COMSEC equipment.
  • Improved SATCOM performance incorporates the enhancements included in ECP-060/FC-1 to the ANDVT. This includes an extended preamble for improved synchronization, selectable receive (RX) or transmit (TX) priority to prevent transmission conflicts, Milstar mode requirements, push-to-talk (PTT) inhibit, and a bridge for signal fades.
  • The latest DOD LPC-10 algorithm (V58) has been enhanced to provide high-quality secure narrowband voice for military handsets and to maintain that quality and intelligibility in noisy acoustical environments.

AIRTERM: NSA is developing AIRTERM. Although originally designed for airborne applications, the Navy has also identified submarine, shipboard, Marine Corps communication vans, and landing craft air cushion (LCAC) requirements. AIRTERM incorporates MINTERM and VINSON operational modes. It is a wideband/narrowband terminal that interoperates with the TACTERM, MINTERM, VINSON, and Single Channel Ground and Airborne Radio System (SINCGARS). The AIRTERM is a lightweight, self-contained secure voice and data terminal that provides secure half-duplex voice, digital data, analog data, and remote-keying capabilities for transmission over radio circuits or wireline media. AIRTERM accepts classified analog voice information and uses advanced speech processing algorithms: LPC-10 at 2.4 kbps in narrowband voice modes and continuously variable slope delta (CVSD) modulation at 12 kbps and 16 kbps in wideband voice modes. The AIRTERM provides the same connectors, with similar functional pinouts, as the VINSON for the wideband operational modes. The AIRTERM is also available with a remote control unit (RCU), Z-AVH, which is functionally equivalent to the Main Terminal Unit (MTU) with regard to external controls.

CHARACTERISTICS


NSA has determined that the ANDVT Family does not process, store, or utilize a date in its operations. Therefore, the year 2000 problem does not affect this product; NSA memo of 12 Jun 98 applies.
