However simultaneously a maximum number of 5 simultaneous timeslots can be used in both uplink and downlink.

A commonly used value is class 10 for many GPRS/EGPRS mobiles which uses a maximum of 4 timeslots in downlink direction and 2 timeslots in uplink direction. The first number is the number of downlink timeslots and the second is the number of uplink timeslots allocated for use by the mobile station. Multislot class with values greater than 31 are referred to as high multislot classes.Ī multislot allocation is represented as, for example, 5+2. It is a value between 1 to 45 which the network uses to allocate radio channels in the uplink and downlink direction. The multislot class determines the speed of data transfer available in the Uplink and Downlink directions.
