Burst switching apparatus for a hybrid switching and transmission system adapted to carry multimedia traffic components including voice and data in multi-slotted frames, in which components of the traffic to be transmitted from the sources thereof are assigned to respective selected slots in each frame to assure transmission of information generated by each active source within a predetermined bandwidth, and the bandwidth is reallocated as necessary to provide additional slots within each frame to the active sources on a frame-by-frame basis to accommodate the respective bandwidths required for the information generated by those sources from among the total available bandwidth of the system. The reallocation to provide additional slots is achieved by a combination of external control of bandwidth and dynamic allocation of bandwidth, by which the additional slots that are temporarily assigned to any active source are obtained from among those slots to which other sources have priority, on a frame-by-frame basis for only so long as the sources having priority to the temporarily assigned slots are inactive.
