A communication terminal which sends a frame to another terminal when performing a load distribution process using load distribution information appended to a frame that is sent/received between terminals within a communication network, the communication terminal comprises: a communication control part that specifies a sending port used for sending the frame; a load distribution information originating side designation part that stores load distribution structuring information, which is to be appended to the frame and used for generating the load distribution information, by relating to a sending port; a load distribution information transfer processing part that, when the sending port is specified, retrieves the load distribution structuring information corresponding to the determined sending port from the load distribution information originating side designation part; a send information setting part that structures the frame based on the load distribution structuring information and a load distribution information setting format; and a send frame processing part that sends out the structured frame from the sending port.

A method of connecting a line concentrator to other line concentrators in a switching system, wherein a switching unit accommodates the line concentrator is provided. The method includes the steps of analyzing a call received by the switching unit through the line concentrator, and connecting lines that are accommodated by the line concentrator and are connected to the other line concentrators without connecting through the switching unit when the call is detected to be made between the line concentrator and the other line concentrators. Thus, a call can be made to a specific dial number without connecting through the switching unit provided in the switching system. Additionally, a call can also be made by use of another switching unit when a communication path between the switching unit and the line concentrator is overcrowded.

A method of controlling affiliation of a remote line-collection device with a plurality of switches connected via a network includes the steps of providing each switch with a backup-storage area in advance in addition to a normal storage area, and transferring control data of the remote line-collection device from the normal storage area of a first switch to the backup-storage area of a second switch when affiliation of the remote line-collection device is changed from the first switch to the second switch.
