4.1.4.2 Card Management Data The standard provides MTI 800 series network management message class to control the following types of network management activity: • System condition management, which is used to establish and report system availability and to give instructions pertaining to message handling during periods of system unavailability • System security management, which is used to control security aspects of the interchange system such as key and password management and security alerts. These messages may be used as part of a security procedure, e.g., automatic periodic key changes • System accounting management, which is used to identify the end of a reconciliation period. These messages may be used as part of a reconciliation process • System audit controls management, which is used to test integrity of interchange links and/or used as a part of an integrity check or failure recovery scheme • Batch and file transfer header and trailer control management, which is used to denote the start and/or end of batch or file transfer File Action Instruction/Notification Messages (362/340) can be utilized to inform the receiver of a file action to be completed. The sender can periodically specify that the receiver acknowledge the receipt of the most recently sent group of instruction messages. The Da ta Record data element present in these message classes is utilized for the actual transfer of data and may or may not be based on the message types identified in this standard. Data Record data element is variable length and its structure and the content can be specified by the parties involved in the exchange. This allows parties in the transmission to further define the requirements of the Data Record data element, allowing the File Action Instruction/Notification messages to be utilized for Card Management transactions as proposed by the WP4. The types of file actions that are defined by the standard are listed below: • Add record • Change record • Delete record • Replace record • Inquiry • Replace file • Add file • Delete File • Card administration • Reserved for private use Page 17
