Abstract
A CM (105) receives requests for data transfer from a series of UMs (101-103) and from an EM (104). The requests contain the UM (101-103) or EM (104) address and the size of the data packet to be transferred. The CM (105) processes the requests on a FIFO basis, stores the requests in a queue and schedules either a small data channel (415) or a large data channel (420), depending on the packet size to be transferred, an acknowledgement channel (425) and also the corresponding number of required timeslots. The CM (105) picks the first request off the queue and sends a grant to the particular UM (101-103) or EM (104) which receive the grant and immediately access either the assigned small or large data channels (415, 420) in the required number of timeslots and the acknowledgement channel (425).
