The TCU collects telemetry data from the vehicle, such as position, speed, engine data, connectivity quality, etc., from various sub-systems over data and control busses. It may also provide in-vehicle connectivity via Wifi and Bluetooth and implements the eCall function when applicable.
A telecommunication control unit (TCU), line control unit, or terminal control unit [1] (although terminal control unit may also refer to a terminal cluster controller) is a Front-end processor for mainframes and some minicomputers which supports attachment of one or more telecommunication lines. [2]
The typical modern TCU uses signals from engine sensors, automatic transmission sensors and from other electronic controllers to determine when and how to shift. [2] More modern designs share inputs or obtain information from an input to the ECU, whereas older designs often have their own dedicated inputs and sensors on the engine components.
A remote terminal unit (RTU) is a microprocessor-controlled electronic device that interfaces objects in the physical world to a distributed control system or SCADA (supervisory control and data acquisition) system by transmitting telemetry data to a master system, and by using messages from the master supervisory system to control connected objects.

MIL-STD-1553B, which superseded the earlier 1975 specification MIL-STD-1553A, was published in 1978.The basic difference between the 1553A and 1553B revisions is that in the latter, the options are defined rather than being left for the user to define as required.
The on-board data handling (OBDH) subsystem of a spacecraft is the subsystem which carries and stores data between the various electronics units and the ground segment, via the telemetry, tracking and command (TT&C) subsystem. [1]
Telemetry & Command Station (TCS), RAF Oakhanger, in England, operated by the United Kingdom and supporting the Satellite Control Network through a Memorandum of Agreement between the UK Ministry of Defence and the US Department of Defense; callsign LION. As of 2010, the site includes three sides, two ARTS and an RBC.
The Telemetry Acquisition Unit (TAU) consists of electronic switches for various heaters for the "warm" sides of the telescope. In addition, there are switches for the deployment actuators, and the bulk of the telemetry processors (e.g. measuring temperatures, electric power, fuel levels, etc.). The TAU communicates with the central computer ...
