Abstract: An attachment mechanism for attaching to a wall a network device for assisting a communication device in communicating on a network includes a heat radiation member, engaged with and supporting a housing of the network device, for radiating heat from the network device, and an attachment member, engaged with the heat radiation member, for attaching to the wall the heat radiation member engaged with the housing.

Abstract: A network concentrator is mounted on a mounting surface using a mounting piece. The network concentrator includes a mounting hole in a mounting part. If the mounting surface is not magnetic, a protrusion such as a screw is inserted into the mounting hole. If the mounting surface is magnetic, a mounting piece is used. The mounting piece has such a form as to be inserted into the mounting hole, and is provided with a magnet. The magnet is attached to the mounting surface, and a part of the mounting piece is inserted into the mounting hole to mount the network concentrator on the mounting surface.

Abstract: It is an exemplified object of the present invention to provide a media converter so shaped that it may prevent damages and disconnections of an optical fiber cable and facilitates handling of the cable. A media converter of one aspect of the invention includes a converter part, connected to a first medium and an optical fiber cable as a second medium, for converting a signal between the first and second media, and an accommodation part for accommodating the optical fiber cable while maintaining a predetermined curvature.

Abstract: There is provided an accommodation apparatus for a transmission medium, such as an optical fiber cable which includes a housing for accommodating the transmission medium and an arrangement part located in the housing, said arrangement part arranging an orientation of the transmission medium accommodated in the housing so as to prevent the transmission capability of the transmission medium from getting damaged. The arrangement part may include downwardly extending L-shaped posts 116 about which the cable 10 may be wound in a space enclosed by a bottom cover 130. The housing top side 110A is to support an optical to electrical media converter 200 and includes a raised part 114 with an opening 118a for receiving a projecting port 214 of the media connector.

Abstract: A network concentrator is mounted on a mounting surface using a mounting piece. The network concentrator 1 is given a mounting hole in a mounting part. If the mounting surface is not magnetic, a protrusion such as a screw provided on the mounting surface is inserted into the mounting hole. If the mounting surface is magnetic, on the other hand, a mounting piece is used. The mounting piece has such a form as to be inserted into the mounting hole, and is provided with a magnet. The magnet is attached to the mounting surface, and a part of the mounting piece is inserted into the mounting hole, thereby mounting the network concentrator on the mounting surface.

Abstract: A new structure of a communication apparatus allowing cables to be arranged, extra space to be eliminated, and allowing easy operation, is disclosed. A body housing has a flat and cylindrical shape and is provided with connectors at the bottom thereof. The body housing stably stands upright on a stand with the bottom portion thereof being accommodated in the stand. Cables connected to the connectors run through a cable restraint provided in the back side of the stand. The center portion of a front surface of the body housing 100 is slightly recessed allowing easy operation. Also, plural heat-dissipating openings are arranged longitudinally along the both side walls of the body housing.
