In case 2, device 1 occupies first slot in first frame, second slot in second frame and third slot in third frame.In dynamic time-division multiple access, a scheduling algorithm dynamically reserves a variable number of time slots in each frame to variable bit-rate data streams, based on the traffic demand of each data stream.

In all these cases, multiplexer scans the various lines in order and fills the frames and transmits them across the channel.

GSM Tutorial | Time Division Multiple Access (TDMA)

With statistical TDM, time slots are not preassigned to particular data sources. Rather, user data are buffered and transmitted as rapidly as possible using available time slots. As with a synchronous TDM, the statistical multiplexer has a number of I/O lines on one side and a higher speed multiplexed line on the other.
