E-47A device for cryptographic protection of voice information

E-47A device is designed for voice information encryption when operating in radio networks over simplex communication channels with S1-TCHR, S1-TCH and S1-FL-BI interface parameters and also over SW (short waves) aviation channels and satellite digital channels.
This device is designed for operation within standard communication complex like TKS-2E installed on board the airplanes, helicopters and other vehicles.
