Abstract
The invention provides a communication method and system for use in a network for digital data exchange/transfer through a circuit switched network. According to the method and system, a call is given the attribute of an intermittent transfer mode, and a device for identifying attributes is provided on network controls in connection paths so that the network control establishes a path only in response to a data transfer request from identified call and releases the path when the call is held on standby for data transfer.
