Networking Diagram

This section describes the networking information about the NEs.

configure the TDM microwave links according to the following network planning information (as shown in Figure 1):

NE11 to NE16 are RTN 950 NEs.
The service capacity accessed by each BTS is provided in Table 1.

To improve transmission reliability of important services, the microwave links between NE11 and NE12, between NE13 and NE14, and between NE13 and NE15 are configured with 1+1 HSB protection.
The ATPC function is enabled to reduce inter-site interference.
