German: Enhanced Circuit Switched Data
Japanese: 高速回線交換データ(ECSD)

Communications engineering. A further development of HSCSD. Together with EDGE it leads to a considerable rise in the data rate of GSM. This is gained through the bundling of data channels and the absence of an error correction. ECSD works with an adaptive modification of the data rate according to the transmission quality.
