TDM
Short for Time Division Multiplexing, a type of multiplexing that combines data streams by assigning each stream a different time slot in a set. TDM repeatedly transmits a fixed sequence of time slots over a single transmission channel. Within T-Carrier systems, such as T-1 and T-3, TDM combines Pulse Code Modulated (PCM)streams created for each conversation or data stream.

- TDMA
Short for Time Division Multiple Access, a technology for delivering digital wireless service using time-division multiplexing (TDM). TDMA works by dividing a radio frequency into time slots and then allocating slots to multiple calls. In this way, a single frequency can support multiple, simultaneous data channels. TDMA is used by the GSM digital cellular system.
- TDR
Time Domain Reflectometry is used to pinpoint flaws and problems in underground and aerial wire, cabling, and fiber optics. Time Domain Reflectometers send a signal down the conductor and measure the time it takes for the signal — or part of the signal — to return. The signal’s reflection begins at the flaw point. Once […]
- TEM
Short for telecommunications equipment manufacturer.
- TCP-Friendly Rate Control
TCP-Friendly Rate Control (TFRC) is a congestion control mechanism designed for unicast flows operating in an Internet environment and competing with TCP traffic. It is designed for applications that use a fixed packet size, and vary their sending rate in packets per second in response to congestion. TFRC is a receiver-based mechanism, with the calculation […]
- Thin Film Transistor (TFT)
Short for thin film transistor, a type of LCD flat-panel display screen, in which each pixel is controlled by from one to four transistors. The TFT technology provides the best resolution of all the flat-panel techniques, but it is also the most expensive. TFT screens are sometimes called active-matrix LCDs.
