3 ^m Message terminal UA 8296/00 r^i Section 1 REQUIREMENTS FOR MILITARY COMMUNICATIONS Modern military communications systems rely increasingly on digital data transmission using compact, microprocessor-based terminals. Growing demand is placed on fast, reliable and secure operation in severe environmental conditions and varying combat situations, with a high degree of immunity from enemy ECM techmgues. ^i Philips Usfa digital messaqe transmission terminals provide a continuously developing family of state-of-the-art devices designed to meet the requirements of the fast-developing area of tactical communications. This booklet describes Philips Usfa's personal, hand-held message terminal UA 8296/00 which, together with the compatible Short-Burst Message Terminal UA 8295/00, can be connected in various ways to form a wide variety of secure and efficient tactical communications networks. The ECOI technigues incorporated in the terminal include fast transmission, automatic error correction and a fixed-message-format option. These measures reduce "on-air" time to a minimum, making it difficult to locate or jam the associated transmitter. Data security is further enhanced by message encryption and by the incorporation of a real-time clock and non-volatile memories. FH

The eguipment employs state of the art microprocessor technology and contains a high-grade digital enciphering algorithm. TWI ECCM Message formats Error correction Enciphering Transmit and receive memories Message transmission Message reception The unit contains a data modem for fast transmission, and an automatic error-correction facility which minimises the need to re-transmit messages. By minimising "on-air" time, these features protect the associated transmitter against enemy direction-finding and jamming technigues. Free-format and telegraphy-format messages can be composed and edited from the keyboard. The error-correction code employed allows the correction of seven bit errors within each 127-bit block. To minimise the effects of error bursts, blocks for transmission are interleaved. The enciphering algorithm is implemented in software and can be tailored in accordance with customer's reguirements. The keyword reguired by the algorithm is entered from the keyboard. Separate transmit and receive memories are incorporated, each with a maximum capacity of 2000 characters. The receive memory can store up to eight messages simultaneously. Messages can be transmitted from either memory. The terminal automatically enciphers the message and adds the ID codes of the sending and receiving stations, the automatically-generated keyword and the time of transmission. In the receiving mode, error-detection/-correction and deciphering are also performed automatically.

5 ps*l 'Sfl Off-line mode Automatic acknowledgement Power supply Communicat ions interface Messages in the memory can be enciphered or deciphered off-line; the results can be read from the display. The built-in automatic acknowledgement facility can be selected or disabled from the keyboard. After transmitting a message, the sending terminal waits three seconds for the acknowledgement. The terminal is powered by six standard (AA-size) dry cells or by an external supply of 10-30Vdc. To conserve battery power the display is turned off 30 seconds after the last keystroke; it can be turned on again by pressing any key. The terminal is connected to the radio eguipment via an external 7-pin connector. Input level: to 2.5 volts (AGC circuit incorporated) Input impedance: 600 ohms Output level: 1.5 mv into 150 ohms The built-in FSK data modem operates in the band between 1100Hz and 2300Hz. Transmission rate is 150 or 600 Baud, selected from the keyboard. In the receiving mode, the terminal automatically selects the correct rate. " I p*} T^fid i

6 isst Message terminal UA 8296/00 pw wi [TO j^l Wl fh RSI Section 3 Configuration Key check/change Message composition and editing Message transmission Message reception Message display OPERATION The following functional parameters are established from the keyboard in response to prompts from the microprocessor: - private (i.e. individual) address - group address(es) - fixed key or day's key - automatic acknowledgement on/off - transmission rate (150/600 Bd) The identification code of the original key can be displayed, and a new key can be entered from the keyboard. The keyword itself is never displayed. Free-format and telegraphy-format messages of up to 2000 characters, entered from the keyboard, can be edited with the aid of "scroll left", "scroll right" and "delete" keys in conjunction with the 16-character LED display. Messages can be transmitted either from the transmit or the receive memory, the latter feature enabling the terminal to function as a relay station. The terminal automatically adds the ID codes of the sending and receiving stations, the keyword, and the time of transmission; it also automatically enciphers the message and adds error-correction information. The terminal automatically deciphers the received message. Discrepancies that cannot be dealt with by the error-correction facility are signalled on the display. Any message in the receive memory can be displayed by keying in a single- digit identification number which is automatically allocated when the message is received. The header information is displayed first, and the entire message can be read with the aid of the "scroll" keys.

7 Off-line encryption and decryption Plain text typed into the transmit memory or stored in the receive memory is automatically encrypted on command from the keyboard. The five-character groups of cipher text can then be read from the display with the aid of the " scroll left" key. The decryption process is similar. The terminal displays a message to denote the presence of format errors which prevent successful decryption. wi rei *wi FW Fil rw
