The ASSB-256 wire-in Encryption module is a low rate voice HF modem for secure communications. The ASSB-256 can be fitted to most modern HF transceivers and VHF/UHF radios. Secure Voice communications are critical to protecting private information and confidential conversations from casual eavesdroppers, the public, business competitors, criminals, terrorists and enemies. Add-on Voice security units used to keep confidential information away from unwanted listeners to protect businesses, property and personnel.
A voice part of the ASSB-256 includes all elements of typical digital voice encryption system: a digital speech coder (vocoder) which transforms the speech into a digital bit stream, a digital encryption and decryption block to encode and decode the bit stream, and a modem to transmit and receive the encrypted digital information.
The user of the ASSB-256 can work with one of 3 (three! – 600, 1200 or 2400 bps) Digital Voice rates of built-in vocoder selected by user in depending on the current propagating conditions. The ASSB-256 will automatically detect and processes the incoming Digital Voice with different rates (Autobauding). The ASSB-256 will automatically detect and processes the incoming clear or encrypted Digital Voice (Automode). A data part of the Defender is a 3 rate HF modem – 600, 1200 and 2400 bps. The ASSB-256 has an ability to be upgraded with any future improvements via upgrade file. The programming and key loading is occurred via PC.
The ASSB-256 is supplied with ASSB-256 wiring loom and comes in two versions v1-vocoder 600/1200bps or v2-vocoder 1200/2400bps
