If the called telephone is attached to another end office, a procedure is used that each end office has a number of outgoing lines to one or more nearby switching centers, called toll offices. These lines are called toll connecting trunks.
Toll connecting trunk is a trunk connecting one or more end offices to a toll center as the first stage of concentration for intertoll or long distance traffic.
Trunking is a method for a system to provide network access to many clients by sharing a set of lines or frequencies instead of providing them individually.
A trunk is a single communication channel between two points, each point being either the switching center or the node.
