The DRS TA-1035(A)/U Digital Non-secure Voice Telephone (DNVT) with digital data port is a four-wire telephone set which transmits and receives conditioned diphase-modulated digital data, digitized voice and digital loop signaling at 16 or 32 kbps. Loop signaling consists of sequences of cyclically permuted 8-bit control words, each word having minimal correlation with any other word. Loop signaling conforms to Tri-Tac Standards.  1, record 4, English, - digital%20non%2Dsecure%20voice%20telephone

Once a call is established, the TA-1035(A)/U can alternate between voice and data modes. For voice communications, the DNVT uses continuously variable slope delta modulation encoding/decoding at 16 or 32 kbps. Extension network analog data interface is provided via the data port. For data communications, the TA-1035/U data adapter interfaces directly with standard Data Terminal Equipment(DE) such as the AN/UXC-7 tactical facsimile machine and AN/UGC-144 communications terminal. Data calls may be placed manually via keypad or automatically via extension dialing through the data port.  1, record 4, English, - digital%20non%2Dsecure%20voice%20telephone

Il s'agit de la transmission discontinue, qui s'appuie sur le fait que tout signal de parole est en fait composé d'un grand nombre de silences. Dans ce cas, la station mobile, tout comme la station de base, car la fonction peut être mise en service dans les deux sens, n'émet un signal que lorsque celui-ci est porteur d'information.  1, record 9, French, - transmission%20discontinue

A transducer which uses voice sound pressure on a diaphragm to compress carbon granules between electrodes. The resulting resistance variation modulates a battery current flowing between the electrodes, thus translating the acoustic message into an analog electrical signal.(SMICO, 71 : 433) As Mrs. Smith talks into her handset, the minute variations in air pressure caused by her voice result in resistance fluctuations in the carbon transmitter.(ENBELL, 80 : 36)  1, record 11, English, - telephone%20transmitter
