Networking Diagram

This section describes the networking information about the NEs.

Configure microwave links according to the network planning information (as shown in Figure 1).

NE32 to NE34 are RTN 950 NEs.
The AM function is enabled for each microwave link.
To improve transmission reliability of important services, the microwave links between NE32 and NE33 are configured as a 1+1 HSB protection group.
The service capacity accessed by each BTS is provided in Table 1.
Table 1 Service capacity accessed by each BTS

BTS BTS32 BTS33 BTS34

Capacity of high-priority services (Mbit/s) 5 1 4

Capacity of low-priority services (Mbit/s) 24 15 4

NOTE:
High-priority services are services that require transmission guarantees. High-priority services cannot be discarded in modulation scheme shifts. Low-priority services are services that do not require transmission guarantees. Low-priority services can be discarded in modulation scheme shifts.
