maintenance. Since the signals are transmitted through fewer 

intermediate links along the path, the reliability of transmission is 
higher. This networking mode is typically employed in densely 

populated urban areas. 

2.  Chain networking mode 

The chain networking mode of the ZXG10-BTS (V2.9) is shown in 

Figure 76.

Each line represents a bidirectional E1 line. The specific ID DIP switch 

at the site should be set based on the actual configuration.   
Chain networking is also applicable to the one-site multi-BTS situation. 

Since signals go through more links, the line reliability is relatively poor. 
This networking mode is applicable to stripe-like areas with a small 

population, thus saving a large number of transmission devices. To 
prevent the clock performance deterioration, it is recommended no 

more than four BTSs be cascaded in the chain networking mode.  

3.  Tree networking mode 

The tree networking mode of the ZXG10-BTS (V2.9) is shown in Figure

Each line represents a bidirectional E1 line. The specific ID DIP switch at 

the site should be set based on the actual configuration.   

The tree networking mode is applicable to large yet sparsely populated 

areas. This mode is complicated, in which signals have to pass many 
nodes and the line reliability is relatively low. And the fault from the 

upper-level SITE may affect the proper running of the lower-level SITE. In 
the tree networking mode, the BTS connected with BSC is the central node, 

which may branch into five nodes, or BTSs.
