High Speed Circuit Switched Data (HSCSD) is a new circuit switched data bearer (CSD) that offers considerably higher throughput than is currently available with CSD. HSCSD is similar to CSD in that a subscriber is allocated a single core time slot for the duration of the call. This timeslot is still limited to 9 600 bits per second throughput. However, using HSCSD the MTN network can also allocate the subscriber up to three additional timeslots as they become available on the network. Un-used resources on the network are put to work and not “wasted”.

By using the three additional time slots the subscriber will experience data transfer speeds up to four times the existing data transfer rates. In reality, handsets will initially support three timeslots for downloads (3 x 9 600 = 28 800 bps) and two timeslots for uploads, due to design constraints. There are two possible configurations that allow the subscriber to decide how many time slots to dedicate to either downloads (down) or uploads (up). These are: 3 down, 1 up, or 2 down, 2 up. Data transfer speeds are expected to increase by a further 50% within the next six months.
