High Speed Circuit Switched Data
HSCSD

    (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).
