High Speed Circuit Switched Data (HSCSD) is a new service that will be introduced in the next expansion phase 2+ for GSM standards. HSCSD allows a substantially higher data transfer rate than with present GSM networks (9600 kbit/s). With the introduction of the new service, manufacturers of mobile and base stations will need to perform numerous new tests. Digital Radiocommunication Test Set CRTC from Rohde&Schwarz, two of which can be combined to produce a multislot test platform CRTx-DUO [1], is ready for the new service.
