Maintenance Management

5.2.1 Security ManagementThe BTS3012 authorizes maintenance engineers with hierarchical operation rights to ensure the security. At the same time, it prompts the possible outcome of dangerous operations.

5.2.2 Alarm ManagementThe alarm management function of the BTS3012 can detect and report equipment faults and abnormal functioning in a real time manner.

With this function, the BTS3012 can collect, clear, query, handle, save, explain, prompt, filter, and analyze alarms.

In addition, the online help and layered alarm filtering function help you to quickly locate faults and provide fault recovery methods.

Providing backup management for the active/standby DTMU.



6 Reliability

6.1 System ReliabilityThe BTS3012 is designed after overall analysis on system reliability. The BTS3012 uses the following methods to enhance the system reliability:

Active/standby mode

Load sharing

Redundant configuration

Optimized fault detection of boards and system

Optimized fault isolation

Redundancy

The BTS3012 uses the redundancy design. The key clock bus, control bus, data bus, DTMU modules use 1+1 backup mode. The transceivers mutual aid is also supported.

System Monitoring

The BTS3012 can automatically detect and diagnose faults in the hardware or software and report them through alarms. It can also detect environmental status and report abnormalities in time.

6.2 Hardware ReliabilityThe BTS3012 uses the following methods to enhance hardware reliability:

Prevention against Mistakenly Inserted Boards

Redundancy Design of Fan Box

Protection against Excessive Rise in Temperature of the DTRU

Reliability Design for Power Supply

Excellent Lightning Protection Design



Prevention against Mistakenly Inserted Boards

When a functional board is inserted into a wrong slot, it cannot get into full contact with the backplane. This prevents the equipment from being damaged.

Redundancy Design of Fan Box

The fan uses N+1 redundancy backup mode. If a fan is faulty, the other fans run at full speed. Under normal temperature, this design can meet the heat dissipation requirement.

Protection against Excessive Rise in Temperature of the DTRU

When the temperature around the last level power amplifier is too high, the power amplifier reports the excessive rise in temperature through an alarm, and then enters into the automatic protection state.

Reliability Design for Power Supply The power supply has the lightning protection function and the protection

function against voltage variation.

The BTS3012 provides the power failure protection for programs and key data.

The boards provide protection against excessive voltage and current.

The boards provide protection against reverse-polarity connection.

Excellent Lightning Protection Design

The BTS3012 needs no external lightning protection device. The antenna ports of the DDPU have the 8KA/40KA lightning protection capability. The lightning protection of the BTS3012 is implemented by directly connecting the conductor inside the DDPU antenna ports to the ground.

6.3 Software ReliabilitySoftware reliability is reflected in the powerful capability of error tolerance. The entire system will not get corrupted when the software fails. That is, the system has self-healing capability. Error tolerance of the BTS3012 is shown in the following aspects.

Regular Check on Key Resources

Seizure check is conducted on various software resources in the system. The check mechanism can ensure the release of hung-up resources and the output of the related logs and alarms.

Task Monitoring

When the software is active, the task monitoring function can monitor any possible fault in the software or hardware. In addition, detected faults can be reported. Task status and system abnormalities can also be monitored.



Data Check

The system can perform regular or event-driven checks on data consistency, restore the data consistency selectively or preferably, and output related logs and alarms.

Saving Operation Log Information

The system records user operations within a certain period and saves the recorded information to the system operation logs. The operation logs can be used to locate errors or exceptions because of incorrect operations so that the system can be restored to the normal state.
