High Speed Circuit Switched Data

High Speed Circuit Switched Data

(communications)
(HSCSD) A planned feature of GSM Phase 2 defining a standard for circuit switched data transmission over a GSM link at up to 57.6 (78.8?) kbps. This is achieved by concatenating up to four consecutive GSM timeslots, each of which is capable of 14.4 kbit/s. It uses multiplexing and compression or filtering.

The following services toward the fixed network are supported: V.34 up to 28.8 kbps and V.110 with rate adaptation up to 38.4 kbps.

HSCSD is aimed at mobile workstation users. As it is circuit switched, it is suited to streaming applications such as video conferencing and multimedia. Bursty applications like electronic mail, are more suited to packet switched data (as in GPRS).
