ABSTRACT:
A data transmission control system in which each terminal sends to a node connected to the terminal a call setting signal including data transmission band parameters such as best and worst band values and call priority required for call setting. Each node manages the data transmission band parameters for each call, the node when detecting generation of a call with high priority calculates a new data transmission band of an associated call with low priority as necessary, and sends a control signal for change of the data transmission band to the terminal handling the associated call even during communication of the associated call. The terminal changes the current data transmission band to the data transmission band indicated by the control signal to thereby control the data transmission band even when the terminal is in a communication state, whereby line traffic can be flattened and line operating efficiency can be increased.
