ABSTRACT:
A dynamic band allocation system wherein the bands of a SD-I line 20 are divided into a sub-rate band used by sub-rate units and a bit multiplex band, the sub-rate band being used as an on-demand band where a trunk and a channel are selected dynamically for connection according to demand, the bit multiplex band being divided into a fixed connection band and a fixed allocation band wherein terminals having a small speed unit are bit multiplexed so that the sum of the signaling speed of the terminals is closest to the speed of the sub-rate unit, and when call is originated from the terminal, selecting only the trunk matching its signaling speed for connection, and further dividing the on-demand band into areas for voice and for data, wherein the ratio of the division of voice/data is changed according to the traffic from time to time.
