Integrated Services Digital Network - Integrated Services Digital Network (ISDN) is a circuit-switched telephone network system, designed to allow digital transmission of voice and data over ordinary telephone copper wires, resulting in better quality and higher data speeds than are available with analog. More broadly, ISDN is a set of protocols for establishing and breaking circuit switched connections, and for advanced call features for the user.
HF Spectral Occupancy Experiment - The HF Spectral Occupancy Experiment is a programme of research undertaken by the Digital Communications Department at University of Manchester Institute of Science and Technology to measure and analyse the usage of the high frequency (HF) portion of the electromagnetic spectrum (3MHz to 30 MHz) over Northern Europe.
Near-Term Digital Radio - The Near-Term Digital Radio (NTDR) program provided a prototype mobile ad-hoc network (MANET) radio system to the United States Army. The MANET protocols were provided by Bolt, Beranek and Newman; the radio hardware was supplied by ITT.
Digital Process Communications - Digital Process Communications protocols originated with the first smart transmitters for process measurement made by Honeywell in the 1980s. Since then other process instrument manufacturers have produced smart transmitters.
DAVIC - DAVIC, Digital Audio Video Council, was founded in 1994 with the aim of promoting the success of interactive digital audio-visual applications and services by promulgating specifications of open interfaces and protocols that maximise interoperability, not only across geographical boundaries but also across diverse applications, services and industries. It was a non-profit international organization based in Switzerland.
