Chapter 1 - System Architecture
Confidential and Proprietary Information of ZTE CORPORATION 15
ZXG10 OB06 (V1.0) looks concise, features compact structure, high
performance of electromagnetic shielding and good heat dissipation.
Both the front door and back door of the cabinet can be opened to
facilitate maintenance.
5. Modular design in software/hardware.
The software/hardware of the ZXG10 OB06 (V1.0) is of a modular
design to reduce the types of its boards and modules, enhance the
integration of the boards, facilitate installation and maintenance for the
projects, and improve the reliability of the system.
6. Advanced software radio technology.
With the advanced software radio technology, the ZXG10 OB06 (V1.0)
ensures that the RF components would work stably and reliably. It
improves the consistency of the equipment in batches and the massive
production of the equipment.
7. Flexible and reliable Abis interface
Advanced flow control algorithms and variable rate signaling link
technology are used so that multiple logical signaling links can be
configured on the 64 Kbit/s physical link to fully share the bandwidth.
In case of ZXG10 OB06 (V1.0) cascading, if one ZXG10 OB06 (V1.0) is
powered off, the Abis interface link can provide auto-bridging
protection.
8. Secure and reliable power supply system.
The power supply module of the ZXG10 OB06 (V1.0) provides such
functions as lightning protection and electromagnetic filtration. The
PSM provides AC input protection (overvoltage/undervoltage protection)
and DC output protection (overvolt
age/undervoltage protection),
lightening/surge prevention, burst interference resistance, cycle drop
prevention, conduction interference
resistance and anti-
electromagnetic radiation functions.
Since there will be nobody on duty for an outdoor BTS, the power
system is configured with an intelligent control function for equipment
start to protect the system, that is, when the temperature is lower
than -20
˚ C, the DC output will be automatically cut off, and when the
temperature is higher than -20 ˚ C, the DC output will be automatically
restored.
The power system accommodates external high-capacity batteries, and
provides a function for management of secondary power down and
batteries.
9. Perfect environment monitoring capability
Internal smog, flood and over-high/over-low temperature can be
detected automatically.
10. Good heat design
The system features direct heat dissipation by wind. Fans of high wind
pressure and large wind capacity are used, thus ensuring quick and
effective heat dissipation for the modules.
Independ
ent air ducts are design ed for the AEM and TRM, so that the
distance of heat dissipation is shortened for higher efficiency.
