摘要： In a passive optical network system in which signals from a master station to plural slave stations are time-division multiplexed and transmitted, the slave stations different in transmission speed are mixedly contained. The master station (OLU) performs ranging for each transmission speed, and grasps all the slave stations different in transmission speed for each transmission speed, and generates a frame including signals of a suitable transmission speed corresponding to each slave station. When the frame is generated, in a downstream signal in which signals of plural transmission speeds are mixed, a dummy signal is set at a place where the transmission speed is changed, and a time necessary to follow a change in level of a received signal due to a change in optical level caused when the transmission speed is changed is secured. Thereby, each ONU avoids a reception error occurring in the time necessary to follow.

摘要： A passive optical network system (PON) has a plurality of OLTs and ONUs with different transmission rates. OLTs with different transmission rates share information of priority frames and destinations, and determine timing for frame transmission to ONUs so that the signal from each of the OLTs does not collide when multiplied in a splitter. OLTs transmit the data to the ONU as a burst signal to prevent the signals with different rates from colliding. ONU acquires the information of the following burst frames. ONU receives only the signal addressed to the own ONU or with the transmission rate of own ONU, therefore errors in ONUs can be avoided. OLT receives only the signal with the transmission rate of own OLT from ONUs based on the transmission timing from the ONUs shared by the line terminators, errors in OLTs can be avoided.

摘要： In an electronic apparatus in which plural substrates are arranged in a perpendicular direction between plural cooling fans in a lower part of a case and plural temperature sensors in an upper part of the case, any temperature variation by 2° C. in three seconds detected by any one of the temperature sensors is determined to be abnormal, and thermal energy is caused to be discharged from surfaces of substrates on two sides of a flame by raising air flow rates of fans. Expansion of the flame to other substrates is thereby prevented.
