Introduction
Analysis of the core content of the standard
This standard specifies the technical requirements for the network management system of terrestrial digital TV transmitters and repeaters, mainly including:
- Network management system architecture with hierarchical management
- Implementation of three communication protocols: TCP/IP, UDP and SNMP
- RJ45 physical interface and 100Mbit/s communication rate requirement
- Three-level fault classification system (suspension/poor broadcasting/indicator deviation)
Comparison of key technical requirements
| Technical elements | TCP/IP protocol | UDP protocol | SNMP protocol |
|---|---|---|---|
| Default port | 6000 | 6001 | 161 |
| Data format | Hexadecimal (starting with 0x) High byte first | ASN.1 encoding OID format {1.3.6.1.4.1.ABCDE} | |
| Typical applications | Operation diagram distribution Equipment control | Status query Fault reporting | MIB information collection Network monitoring |
Fault management specification
The standard defines a three-level fault classification mechanism:
- Level 1 fault: Severe fault that causes broadcast suspension (such as power outage, cooling system failure)
- Level 2 fault: Intermediate fault that causes poor broadcast (such as amplifier module overload, power abnormality)
- Level 3 fault: Minor fault with deviation of individual indicators
The typical fault handling process should be followed:
Real-time monitoring → Fault classification → Automatic alarm → Log recording → Maintenance response
Implementation suggestions
Key points of system deployment
- Use dual network card redundancy design to ensure network reliability
- Configure NTP time synchronization to ensure consistent clocks of all network devices
- Implement SNMP TrapActive alarm function
Parameter configuration specification
Key parameter setting example:
// Transmitter power threshold setting parameter code 0x101B (output power threshold) = 5000 // Unit: Watt parameter code 0x101C (reflected power threshold) = 100 // Unit: Watt
