Summary This document consists of seven chapters and three appendixes. This chapter introduces the measures taken in reliability design of the BTSAE from the aspects of system, hardware and software.

Content The appendix lists the glossary involved in this manual. The appendix lists the acronyms and abbreviations involved in this manual. Figure 1. Used in highly populated areas with high traffic volume or in the areas where wide coverage is required Used in cities, suburbs, and rural areas where high traffic volume and wide coverage are required, or in the areas where the site for an equipment room is hard to find or the construction cost of an equipment room is too high Used in cities and suburbs where medium traffic volume and wide coverage are required Used in indoor coverage, towns and suburbs where low traffic volume and wide outdoor coverage are required.

Having strong coverage capabilities, the BTSAE is intelligently designed with low power consumption, thus saving the operation expenditure. Some of the features of the BTSAE are low construction cost, fast network deployment, and strong environment adaptability. Configuration of up to six cells in one cabinet Hybrid networking of multiple frequency bands is supported.

Each site supports TRXs. The external storage batteries can provide up to AH power. It complies with the International Protection standard IP55 in terms of water prevention and dust prevention. The BTSAE has a powerful temperature control system, which enables it to adapt to various adverse environments.

However, in severely polluted areas, such as chemical factories, the life of the fan filter unit will be severely affected. It is configured with built-in DELU and a power lightning protection unit. It has the following benefits in terms of installation. All the external cables are introduced into the cabinet through the bottom of the cabinet. A mm high space is reserved for the cabling, which greatly facilitates the maintenance.

Field installation personnel only need to secure the cabinet and install the external cables. The simple and fast installation of the hardware and software greatly reduces the installation time and facilitates fast network deployment. It can meet your requirements in any region. The reserved space provided by Huawei is of two configuration modes:. According to the function of the modules, it can be divided into the following subsystems:. Common subsystem Double-transceiver subsystem RF subsystem Power supply subsystem Monitoring subsystem.

The BTSAE integrates these modules into a cabinet to form a base transceiver station that fully complies with the outdoor protection standards and can operate independently.

The BTS common subsystem performs the following functions:. Managing and controlling other subsystem and modules. Protecting E1 signals from lightning Protecting monitor signals from lightning Connecting cabinets to form a cabinet group Providing lightning protection for the signals between cabinet groups when their distance is 25 meters.

Outputting and inputting signals Forwarding the cabinet group signals from the common subsystem to the DSCB. Providing lighting protection for eight external Boolean value inputs Providing a 2-route serial control bus port.

Providing lighting protection for 4-route E1 signals Providing lighting protection for the signals between BTSAE cabinet groups when their distance is 2 5 meters. Baseband signals processing RF receive processing and transmit processing Power amplification Transmit diversity and 4-way receive diversity PBT.

Processing the RF and baseband signals of two carriers Processing baseband frequency hopping and RF hopping Supporting enhanced functions such as PBT, transmit diversity, and 4way receive diversity.

Sending the multiple channels of the RF signals from the transceiver to the antenna through the duplexer Amplifying the received signals from the antenna and divides the signals into four parts and then sending them to the transceiver Sends the multiple channels of RF Tx signals from the DTRU transmitter to the antenna through the duplexer after combination.

Sends the received signals from the antenna to the duplexer and to the low noise amplifier and divides the signals into several routes and then sends them to the receivers of the DTRUs. Combines the four routes of signals into one route, auto detects the frequencies of the input signals and performs automatic tuning.

Transmitting signals Receiving signals Combining frequency Performing loopback test Amplifying power Outputting the power individually Outputting the combination power. It performs the following functions:. Monitoring the PSU, storage batteries, and the internal environment of the cabinet Inputting 6-route external Boolean values and outputting 2-route Boolean values.

Managing and monitoring the internal environment of the cabinet, the power supply system, and the charging and discharging of the storage batteries, and reporting the monitoring results to the DTMU Collecting the environment parameters such as the temperature, humidity, smoke, and water immersion sent from the sensors, and then reporting the result to the DTMU.

When the temperature exceeds the threshold, the system generates alarms. Description Enhanced full rate speech service Full rate speech service Half rate speech service Adaptive multi-rate 9. By carrying out terminal maintenance, you can operate and maintain sites, cells, and TRXs. The PC forms a. You can see the name, type, location, number, and running status of each NE through the GUI interface. You can view the detailed performance data, alarm data, and configuration data of an NE.

You can also operate or maintain an NE through the topological view. At the same time, it prompts the possible outcome of dangerous operations. With this function, the BTSAE 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 carry out fault recovery measures. It supports both dynamic and static data configurations. Downloading software to boards or modules, or starting and initializing boards or modules Recording the interface tracing messages and running status of the BTS through logs Implementing in-position tests on boards Testing the Abis link of the DTRU, testing channels, and self checking the site,.

System Monitoring The BTSAE 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. Prevention Against Mistakenly Inserted Boards When a functional board is inserted into a wrong slot, it does not come in full contact with the backplane. This prevents the equipment from being damaged. 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.

The power supply system has the power environment monitoring system, which performs the following functions:. When the external power supply fails, the internal storage batteries of the BTSAE can supply power for several hours. An alarm about the failure of the external power supply is sent to the OMC to prompt for proper handling.

When a module fails, an alarm is sent to the OMC. The power supply has a lightning protection function and a function for protection against voltage variation. The entire system is not corrupted when the software fails. That is, the. Regular Check on Key Resources Seizure check is conducted on various software resources in the system. The check mechanism can ensure the release of suspended 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. 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. Other External Interfaces 7. It complies with the following standards:.

The protection level reaches IP The fan filter unit has functions such as waterproof, dustproof, and anti-mildew.
