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
Conventional maintenance
This method is applied on regular basis to observe the operation of the system, test
and analyze equipment performance.
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
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.
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.

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.
