The function of audit programs is to detect and to eliminate erroneous or inconsistent information in the CS memory All of the audit programs are scheduled by the MAC program for routine execution throughout the day usually on an hourly basis Most of the audit programs can be requested via the TTY Also the audit programs are requested by the MAC program when program indicators warn of possible trouble 12 02 To detect errors in the CS audit programs use the following methods a Compare redundant distinct from duplicate information Redundant information exists if it can be found in a number of different forms within the CS Duplicate information exists when an exact copy of it is available in a PS or in a different CS b Determine whether portions of the information violate certain restrictions c Compare information in the CS with associated backup information in the PSs 12 03 When the audit program detects either a restriction violation or a disagreement between redundant information all equipment associated with the suspect CS memory location is made idle and is available for use when required When a disagreement between the PS and the CS memory is detected the audit program corrects the CS Audit program results are printed out by the maintenance TTY of the master control center 12 04 emergency action control program combines the individual audits into groups for use when the existence of trouble
