適用范圍：1 This International Standard defines the means by which a data communication system operating according to the basic mode control procedures defined in ISO/R 1745 can interchange information messages in a fast conversational manner and where the operator plays a significant role in the operation of the terminal.2 This International Standard extends Phase 3 (information transfer) as defined in ISO/R 1745, to allow two stations connected by a data link to reverse their master/slave status, thereby reversing the direction of the information transfer, without leaving Phase 3.3 During one conversation process considered here, only two stations are involved at one time. Conversation with any other station requires termination of the existing data link and establishment of another data link.4 This procedure applies to the following system configurations : point-to-point, centralized multipoint.
