circuit switched data (CSD)

The CSD service (Circuit Switched Data) is a data transmission service in GSM networks

.This circuit switched CSD service operates at 9.6 kbit/s and is characterised by its low bit error rate, which is achieved by special radio protocols and complex error correction. In order for the CSD service to work without errors, a perfect radio connection between the mobile phone or the radio modem and the base station is required. Radio connections that are susceptible to interference reduce the relatively low data rate and increase the probability of errors.
