VDict mobile



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
applications like electronic mail, are more suited to
packet switched data (as in GPRS).
