摘要： Switching process at the occurrence of a path trouble is performed more quickly to reduce the number of packet discards during a traffic transition from a currently used system path to a standby system path within a section to be protected. An OLT (210-W) refers to the DBA information of a PON section and, if receiving no CCM frame at a timing at which the same should be received, then determines that some trouble has occurred on the path (S801) and transmits, to an OAM-compliant NE (200-Z), an application-for-switching frame (1501) to notify the OAM-compliant NE (200-Z) of the abnormal condition. The OAM-compliant NE (200-Z) monitors the occurrence of the trouble within the PON section nearly in real time, starts a switching process (S802) and generates and transmits a standby-system delivery request (321) (S302, S803). An OAM-compliant NE (200-A) switches the communication path to the standby-system passing through an OLT (210-P).

摘要： An optical line terminal (OLT), an optical network unit (ONT) and a passive optical network (PON) system are provided. A user of the ONU or a terminal connected with the ONU can accurately recognize the amount of a bandwidth allocated to the ONU without estimating the communication bandwidth. The OLT notifies each ONU of the amount of the bandwidth allocated to the ONU in response to a request transmitted from the ONU to the OLT. Each ONU receives bandwidth information from the OLT and displays thereon the bandwidth information or notifies the terminal connected with the ONU of the bandwidth information.

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.
摘要翻译： 无源光网络系统（PON）具有多个具有不同传输速率的OLT和ONU。 具有不同传输速率的OLT共享优先级帧和目的地的信息，并确定向ONU发送帧的定时，使得来自每个OLT的信号在分离器中相乘时不会发生冲突。 OLT将数据作为突发信号发送到ONU，以防止具有不同速率的信号相互冲突。 ONU获取以下突发帧的信息。 ONU仅接收寻址到自己的ONU的信号或以自己的ONU的传输速率，因此可以避免ONU中的错误。 基于来自线路终端机共享的ONU的传输定时，OLT仅从ONU接收到自身OLT的传输速率的信号，可以避免OLT中的错误。
