-   Diagram displaying the packet core architecture. The packet core includes the following 5G network functions: the A M F, the S M F, the U P F, the U D R, the P C F, the U D M, and the A U S F. The A M F communicates with 5G user equipment over the N1 interface. A G Node B provided by a Microsoft partner communicates with the A M F over the N2 interface and the U P F over the N3 interface. The U P F communicates with the data network over the N6 interface. When operating in 4G mode, the packet core includes M M E Proxy and M M E network functions. The M M E Proxy communicates with the M M E over the S 11 interface. An E Node B provided by a Microsoft partner communicates with the M M E over the S 1 M M E interface.

 Each packet core instance is connected to the local RAN network to provide coverage for cellular wireless devices. You can choose to limit these devices to local connectivity. Alternatively, you can provide multiple routes to the cloud, internet, or other enterprise data centers running IoT and automation applications.
