6 Reliability
6.1 System Reliability
The BTS3012 is designed after overall analysis on system reliability. The
BTS3012 uses the following methods to enhance the system reliability:
z
Active/standby mode
z
Load sharing
z
Redundant configuration
z
Optimized fault detection of boards and system
z
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 in form of alarms. It can also detect environmental
status and report abnormalities in time.
6.2 Hardware Reliability
The BTS3012 uses the following methods to enhance hardware reliability:
z
Prevention against Mistakenly Inserted Boards
z
Redundancy Design of Fan Box
z
Protection against Excessive Rise in Temperature of the DTRU
z
Reliability Design for Power Supply
z
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.

Page18, Total35
Document Title
Security Level
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
z
The power supply has the lightning protection function and the protection
function against voltage variation.
z
The BTS3012 provides the power failure protection for programs and key
data.
z
The boards provide protection against excessive voltage and current.
z
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 Reliability
Software 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 the error or exception because of incorrect operation so that the
system can be restored to the normal state.
