However, the ABis interface of a large number of base station controllers (BSC) is connected to the SDH network of the transmission network. Therefore, the base station side uses the PTN network, while the BSC side uses the SDH network. At this time, the service needs to cross the PTN The network communicates with the SDH network.

Among them, A1 and A2 belong to one core office, and B1 and B2 belong to another core office. The principle of cross-network communication and protection in Figure 1 is as follows: In the SDH network, the C2 network element is connected to the BSC switch, the service of the BSC will be dispatched to the A2 device, and the service of the base station C1 will also be transmitted to the landing device A1 through the PTN network.
