The Joint Communications Unit (JCU) is a unit of the Joint Special Operations Command charged to standardize and ensure interoperability of the communication procedures and equipment of JSOC and its subordinate units. JCU was activated at Ft. Bragg (now Fort Liberty), NC in 1980, after the failure of Operation Eagle Claw.
The Joint Communications Support Element (Airborne) (JCSE) is a United States Department of Defense (DoD) standing joint force headquarters expeditionary communications provider that can provide rapid deployable, en route, early entry, and scalable command, control, communications, and computer (C4) support to the unified combatant commands, special operations commands, and other agencies as ...
Plessey System 250, also known as PP250, was the first operational computer to implement capability-based addressing, to check and balance the computation as a pure Church–Turing machine. Plessey built the systems for a British Army message routing project.
The Software Communications Architecture (SCA) is an open architecture framework that defines a standard way for radios to instantiate, configure, and manage waveform applications running on their platform. The SCA separates waveform software from the underlying hardware platform, facilitating waveform software portability and re-use to avoid ...
ATA 100 contains the reference to the ATA numbering system which is a common referencing standard for commercial aircraft documentation. This commonality permits greater ease of learning and understanding for pilots, aircraft maintenance technicians, and engineers alike.
This announcement was followed by another announcement in July, 1975, which introduced the IBM 3760 data entry station, the IBM 3790 communication system, and the new models of the IBM 3270 display system. [4] SNA was designed in the era when the computer industry had not fully adopted the concept of layered communication.
An optical communication system is any form of communications system that uses light as the transmission medium. Equipment consists of a transmitter, which encodes a message into an optical signal, a communication channel, which carries the signal to its destination, and a receiver, which reproduces the message from the received optical signal.
Many radio systems also require the operator to wait a few seconds after depressing the PTT button before speaking, and so this is a recommended practice on all systems. The California Statewide EMS Operations and Communications Resource Manual explains why: Key your transmitter before engaging in speech.
