Simple application of trunk

Introduction to trunk

"trunk" is generally translated as "trunk line, trunk line, long-distance line" in network terms. In routed / switched networks, trunk is often referred to as "relay (transparent transmission)". In voice-level application lines, trunk generally refers to the "backbone network, telephone trunk", that is, the connection circuit or channel between two exchanges or exchanges, which transfers between the devices at both ends and serves as the transmission link for signaling and terminal equipment data.
