The digital nonsecure voice terminal (Digital Nonsecure Voice Terminal) is a ruggedized field telephone. It is operable as a tabletop device in tents, shelters, and office environments. It also may be operated outdoors while strapped to a tree or pole. The Digital Nonsecure Voice Terminal is designed for durability to exposure of the elements during operation and transportation. Voice communication is accomplished through the handset. Digital data from an external device interfaces through the TA-1042A/U’s digital data port (DDP). The Digital Nonsecure Voice Terminal transmits and receives full duplex, conditioned diphase digital voice and loop signaling information at 16 or 32 kb/s rates. The Digital Nonsecure Voice Terminal is a nonsecure telephone with no encryption capability. It digitizes voice information using continuously variable slope delta (CVSD) modulation. Digital communication transmissions, both to and from the Digital Nonsecure Voice Terminal, are accomplished using a conditioned diphase (CDP) data transmission method. This is accomplished by using the DDP. The Digital Nonsecure Voice Terminal operates in both common battery mode and local battery point-to-point mode, but not simultaneously.
