Abstract
Data communication is started when a first B channel is established between a source terminal and a destination terminal. Immediately before or after the start of a data transmission phase, the destination terminal is called a second time so that a second B channel may be established. Immediately before or after the data transmission phase, the use of one of the B channels is terminated. Accordingly, time required for data communication can be reduced.
