ANDVT


ANDVT is an acronym for Advanced Narrowband Digital Voice Terminal.

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.

ANDVT uses a 39 Tone HF Modem Coupled with the LPC-10 Vocoder for digital voice communications.
