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, fiche 1, Anglais, - 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, fiche 1, Anglais, - digital%20non%2Dsecure%20voice%20telephone

The best known operational demand-assignment multiple-access(DAMA) system is called SPADE(Single-channel per carrier PCM Multiple-Access Demand-Assignment Equipment).... SPADE increased the traffic handling capabilities of INTELSAT satellites and made the establishment of new small capacity links more economical.... In the SPADE system a specific satellite radio-frequency band is divided on the basis of assigning a single data or PCM converted voice channel per RF carrier.... Neither end of a channel is permanently connected with any given terminal, and the channels are paired to form two-way circuits within the demand-assignment pool.  1, fiche 2, Anglais, - Single%2DChannel%20per%20Carrier%2C%20PCM%20Multiple%2DAccess%2C%20Demand%2DAssignment%20Equipment

Le système SPADE. Introduit par INTELSAT dans un réseau vers 1971, c'est le premier système à porteuses monovoies utilisant un répéteur de 36MHz de couverture globale d'un satellite d'INTELSAT (tels ceux de satellites INTELSAT IV, IV-A et V). La bande du répéteur est divisée en 800 canaux de 45 kHz chacun constituant une réserve commune de fréquences utilisables à la demande par n'importe quelle station du réseau. La parole est transmise sous forme de signaux numériques avec modulation par impulsions et codage.  1, fiche 2, Français, - %C3%89quipement%20d%27acc%C3%A8s%20multiple%20avec%20affectation%20%C3%A0%20la%20demande%2C%20par%20porteuses%20monovoies%20et%20modulation%20par%20impulsions%20et%20codage
