Capabilities

This global contract provides DoD VTC users a bridging service using industry standard technology for interoperability and multi-point VTC requirements. Increased flexibility was added to the system by providing subscribers a way to access VTC users on other tactical and non-DoD networks such as FTS2001, commercial networks (Accunet, Sprint, etc.), and tactical networks. DISN Video Services will allow subscribers to access the Navy’s tactical VTC to the Fleet (Video Information Exchange System [VIXS]).
