ABSTRACT:
A data communication method includes the steps of: sending a communication procedure signal prior to data communication; sending a data signal; and sending a stop signal for stopping an echo suppressor function on a communication network; wherein the stop signal is sent prior to the data signal in such a way that a time interval during which no signal is generated does not occur, after the stop signal is sent, until the data signal is sent. A data communication apparatus includes: a communication unit for sending and receiving a data signal; a discrimination unit for discriminating if the apparatus is a calling station; and a control unit for controlling to change a communication controlling mode based on the output from the discrimination unit.
