Abstract: A useful technique for configuring radio equipment as networking radio equipment is provided. Networking radio equipment 3A connected to a first node via a first link and to a second node via a second link includes a first frame processing unit 31a, a second frame processing unit 31b, and a controller 33. The first frame processing unit 31a performs framing/deframing of a layer 1 frame flowing over the first link, and includes a first port that allows input/output of a layer 2 frame. The second frame processing unit 31b performs framing/deframing of a layer 1 frame flowing over the second link, and includes a second port that allows input/output of a layer 2 frame. The controller 33 controls the radio equipment 3A, and includes a control port that allows input/output of a layer 2 frame. A layer 2 switch 35 determines destination of the layer 2 frame.

Abstract: The invention provides a circuit-mounted board which can improve the reliability in the operations of a system having expansion slots. The load adjustment board is a circuit-mounted board to be used by being inserted into the expansion slot of the system, and comprises a plurality of connection pins to obtain electric connection with another board, and devices each having variable electric property, such as a variable resistance or a variable capacitor, provided for each connection pin. One end of each device is connected to the respective connection pin, and the other end is fixed to the predetermined potential (ground, for example). The board is inserted into a vacant slot of the expansion slots of the system to suppress reflection noise etc.
