Circuit switched data. Data transmission of a continuous bit stream from sender to receiver, as in the GSM CSD service. Data transmitted over a dedicated channel. In a mobile context, amounts to using the voice channel for data with corresponding radio loading and cost implications. Compare with Packet data as in GSM GPRS (General Packet Radio Service) and other mobile packet services such as Ericsson Mobitex, Motorola DataTAC, CDPD in AMPS and PDC-P in Japanese PDC networks. CSD is also the most common mode for fixed line communications, as in ISDN or modem connections.
