board integration, facilitating project installation and maintenance, and 
improving the reliability of the system.  
6.  Advanced software radio technology. 
The ZXG10 BTS (V2.9) uses software radio technology to ensure the 
long-term reliable operation of the RF parts and improve the batch 
consistency and mass productivity of 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. 
An E1 can be shared by 15 carriers (under special configuration). 
When multiple BTSs are cascaded, the automatic crossover protection 
function is provided for the Abis interface link when any BTS is 
powered off. 
8.  Secure and reliable power supply system.  
 
The primary power supply supports -48 V supply; the secondary power 
supply with a distributed design is integrated in various modules, 
improving the reliability of the system.  
9.  Perfect environment monitoring capability 
Providing inputs for 10 pairs of external environment trunk nodes, and 
outputs for 8 pairs of trunk nodes. 
10. Good heat design 
A fan layer is designed on the carrier shelf of each layer and can hold 
two fans, monitoring and collecting the temperature inside the carrier 
shelf, thus automatically adjusting the rotational speed of the fans.  
Each layer of the carrier shelf has a separate ventilation duct, and heat 
is dissipated out of the rack through the common duct of the rack. 
11. Convenient local operation and maintenance 
It adopts a standard RS232 interface to connect with the local 
operation and maintenance terminal to spare special cables. 
The local operation and maintenance terminal is easy to learn and use 
since it is consistent with the OMCR interface. 
Perfect local operation and maintenance 
Rapid and reliable online software upgrade.
