User Manual iSiteC ODU3601C CDMA Soft Base Station BTS MaintenanceChapter 1 Routine Maintenance Instructions 1-1 Chapter 1 Routine Maintenance Instructions 1.1 Overview ODU3601C Routine Maintenance Instructions describes in details the contents and methods of ODU3601C routine maintenance operations. It serves as a reference in determining the routine maintenance schedule of a particular site.　1.1.1 Purposes of Routine Maintenance　Normal system operation of ODU3601C in different running environment depends on effective routine maintenance.　ODU3601C routine maintenance is intended to detect and solve problems in due time to prevent trouble.　1.1.2 Classification of Routine Maintenance Operations　I. Classification by implementing methods　l Conventional maintenance　This method is applied on regular basis to observe the operation of the system, test and analyze equipment performance.　l Unconventional maintenance　The unconventional method is to test whether the system performance has degraded by artificially creating some faults.　For example, maintenance engineers may artificially create some faults and test if the alarm system reports alarm correctly.　II. Classification by period length l Unscheduled maintenance　This includes the maintenance operations performed at equipment fault or network adjustment.　For example, maintenance tasks performed due to by user complaint, damage of equipment and line fault. Solving of problems left over by daily maintenance operations is also regarded as unscheduled maintenance operation.　l Daily maintenance　It refers to the maintenance tasks conducted each day.　ODU3601C daily maintenance helps maintenance engineers keep track of the operating conditions of the equipment at any moment so that problems can be solved in time.　When a problem is detected in daily maintenance, record it in detail to help eliminate it in time.　
User Manual iSiteC ODU3601C CDMA Soft Base Station BTS MaintenanceChapter 1 Routine Maintenance Instructions 1-2 l Periodical maintenance　Periodical maintenance refers to the maintenance tasks conducted regularly. Periodical maintenance helps maintenance engineers keep track of the long-term performance of the equipment.　Periodical maintenance includes: monthly maintenance, quarterly maintenance and yearly maintenance.　1.1.3 Usage of Routine Maintenance Records As a maintenance engineer, you are required to fill in the following tables when you conduct the daily, monthly, quarterly and yearly maintenance for your ODU3601C. And specific instructions have been given after those tables. I. Daily unexpected fault handling record　Note down in details the unexpected faults occurred in ODU3601C daily maintenance operations in the table for future reference. The user may modify the record according to the actual needs, or compile the records into manuals. II. Monthly maintenance record　Note down in details the actual maintenance operations carried out during ODU3601C monthly maintenance in the table. For details, see ODU3601C Monthly Maintenance Operation Instruction. III. Quarterly maintenance record　Note down in details the actual maintenance operations carried out during ODU3601C quarterly maintenance in the table. For details, see ODU3601C Quarterly Maintenance Operation Instruction. IV. Yearly maintenance record　Note down in details the actual maintenance operations carried out during ODU3601C yearly maintenance in the table. For details, see ODU3601C Yearly Maintenance Operation Instruction.
