Abstract
A resource usage of a switching section can be reduced and operations for connection can be facilitated in high speed even if a failure occurs on the switching section by a line switching method. The line switching method in an asynchronous transfer mode exchange including a line concentration and distribution device, to which a subscriber circuit for accommodating a plurality of subscribers, is connected and a switching section, includes the steps of comparing information for identifying a path of a subscriber's cell with information registered in a monitor table, detecting that a first subscriber circuit for accommodating a called subscriber is connected to a same line concentration and distribution device to which a second subscriber circuit for accommodating calling subscriber is connected, and looping back and connecting the call sent from the calling subscriber to the called subscriber without passing through the switching section.
