Page 21: Chapter 6 Reliability
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 in form of alarms. -
Page 22: Software Reliability
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. - Page 23 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. 2006-10-04 HUAWEI Confidential Page20, Total35...
