• Inspection Frequency: Full coverage once per quarter
• Execution Requirements: Complete all equipment room inspections within the quarter
• Time Window: Executable at any time during the quarter

Core Value

• Ensure stable operation of core network equipment
• Reduce failure rates through preventive maintenance
• Meet telecom industry maintenance standards
• Optimize equipment lifecycle management

II. Plan Configuration

1. Create Inspection Plan

Operation Path:

1. 【Inspection Management】→【Plan Scheduling】
   
2. Click "New" button

Start Date	2025-Q1 First Day (e.g. 2025-01-01)	Must be quarter start day
Cycle Period	3 months	Quarterly cycle
Trigger Date	3	Generate tasks 3 days in advance
Trigger Time	22:00	Generate next quarter's tasks at 22:00, 3 days before quarter end
Overtime Reporting	No	Cross-quarter completion not allowed
Offline Reporting	No	Offline operation not supported

Key Setting Instructions:
Start date must be set to quarter start day (Jan 1/Apr 1/Jul 1/Oct 1)

III. Task Configuration

1. Single Task Configuration

Operation Steps:

1. Locate target plan
2. Click "Add Task" icon

Parameter Configuration:

Parameter	Value	Description
Task Name	Comprehensive OLT Equipment Inspection	Clear task content
Executing Personnel	Network Maintenance Group	Designated responsible team
Nth Day	1	First day of quarter
Start Time	00:00	Quarter start time
Working Duration	3 months	Full quarter execution window
Execution Frequency	1 time	Single task per quarter

2. Configuration Analysis

• Time Window:
  • Task validity: Quarter start day 00:00 to quarter end day 24:00
  • Flexible execution: Complete within quarter
• Execution Requirements:
  • Cover all OLT equipment rooms
  • Execute according to standard checklist
  • Record key indicators

IV. Task Generation and Execution

1. Automatic Generation Mechanism

• Generation Time: 22:00, 3 days before quarter end
• Generated Content: Next quarter's OLT equipment room inspection tasks
• Task Characteristics:
  • Validity period: Full natural quarter
  • Reminder settings: Push task reminders at quarter start
  • Progress monitoring: Display completion rate

2. Manual Generation Operation

1. Locate target plan
2. Click redo icon in operation column
3. Set time range (e.g. 2025-Q1: 2025-01-01 to 2025-03-31)
4. Click "Confirm" to generate immediately

3. Execution Process

1. Plan Breakdown:
   • Divide execution routes by region
   • Develop monthly execution plan:
     • First month: Complete 30% equipment rooms
     • Second month: Complete 60% equipment rooms
     • Final month: Complete 100% equipment rooms
2. On-site Inspection:
   • Equipment operational status check
   • Environmental parameter monitoring (temperature/humidity)
   • Power/UPS system detection
   • Optical fiber connection quality test
3. Data Reporting:
   • Use specialized testing equipment
   • Automatically synchronize test data
   • Classified reporting of abnormal situations
4. Quarterly Acceptance:
   • System auto-generates quarterly report
   • Completion warning before 20th of final month
   • Complete all inspections before quarter end

V. Best Practices

1. Execution Strategy

Time Period	Execution Focus	Target
Days 1-30	Core hub equipment rooms	30% completion
Days 31-60	Regional backbone equipment rooms	60% completion
Days 61-90	Edge access equipment rooms	100% completion

2. Optimization Suggestions

1. Digital Management:
   • Equipment room QR code identification
   • Mobile scanning input
   • Auto-generate electronic reports
2. Preventive Maintenance:
   • Combine with equipment operational data
   • Predictive replacement of vulnerable parts
   • Establish equipment health records
3. Standardized Operations:
   • Develop checklist templates
   • Key parameter threshold warnings
   • Build typical case library

3. Exception Handling

Exception Type	Solution
Equipment alarm	Immediately initiate emergency repair
Equipment room abnormality	On-site verification within 24 hours
Progress delay	Activate backup team support
New equipment room	Manually add inspection task

VI. Precautions

1. Key Configuration Requirements

• Quarter Definition: Define natural quarters (Jan-Mar/Apr-Jun/Jul-Sep/Oct-Dec)
• Equipment Room List: Update list at quarter start
• Permission Management: Executors need security certification
• Data Security: Encrypted transmission of test data

2. Industry Standards

1. Inspection Specifications:
   • Comply with YD/T 1627 "Technical Requirements for Optical Line Terminal Equipment"
   • Meet GB/T 22239 "Basic Requirements for Network Security Level Protection"
2. Record Requirements:
   • Retain inspection records for at least 2 years
   • Include equipment serial number/software version
   • Electronic signature of maintenance personnel

3. Safety Requirements

• Comply with equipment room access system
• Electrostatic protection before operation
• Two-person presence during backup power testing
• Remote monitoring of sensitive operations
