Abstract: A frame transmission apparatus includes multiple ports provided in a line unit, and a setting control unit. The setting control unit checks the normality of the frame transfer state within the apparatus by transferring a maintenance management frame from a first port to a second port within the apparatus. When the first port is a logical port configured by link aggregation of multiple physical ports, the setting control unit selects each of the multiple physical ports as a transmission source port and transfers multiple maintenance management frames from the multiple physical ports to the second port.

Abstract: A radiological image-capturing device includes: a first read control section that executes a first read mode in which electric signals stored in a plurality of pixels are read out simultaneously in units of a plurality of rows; and an emission-start determining section that determines that the emission of radiation from a radiation source onto an image-capturing panel has started when the values of the electric signals read by the first read control section have become greater than an arbitrarily settable threshold. If it is determined by the emission-start determining section that the emission of the radiation has started, the first read control section terminates the reading of the electric signals, and thereby brings the image-capturing panel into an exposure state.

Abstract: A network system includes a maintenance terminal and a switch that transfers a packet. Upon receiving a link-trace message packet, the switch transfers, when links to the destination constitute a link aggregation, the link-trace message packet to all physical links constituting the link aggregation. In response to the link-trace message packet, the switch receives a link-trace reply packet from each of the physical links, and generates link-trace result data. the link-trace result data is output to the maintenance terminal.
