摘要： The OLT manages information of optical intensity and communication bit rate receivable by each ONU, and transmits a signal at suitable optical intensity and a bit rate. The OLT decides a signal transmission plan for each ONU according to a status of accumulated information waiting to be transmitted in the OLT's own device buffer, and inserts the signal transmission plan in a header or payload of a downlink frame, thereby notifying the ONUs of the information prior to transmitting accumulated information (primary signal). The ONU recognizes the signal transmission plan of the OLT according to the time information in a downlink intensity map, receives only a signal having the optical intensity and bit rate suitable for the ONU's own device, and blocks other signals.

摘要： When a neighbor ONU receives a signal with light intensity high enough to secure communication between an OLT and a remote ONU, the light intensity may be excessively high to damage a receiver of the neighbor ONU. In order to avoid such a problem, each ONU is notified of a downstream signal transmission plan (downstream light intensity map) prior to transmission of a downstream signal. Each ONU receives the downstream light intensity map (light intensity transmission schedule of downstream signal) in advance. Thus, the neighbor ONU can block or attenuate an optical signal addressed to the remote ONU, and the remote ONU can determine normal operation even when the remote ONU cannot receive a signal addressed to the neighbor ONU. Thus, the remote ONU can be prevented from issuing a wrong error signal.
摘要翻译：当邻居ONU接收到具有足够高的光强度以保证OLT和远程ONU之间的通信的信号时，光强度可能过高而损坏相邻ONU的接收机。为了避免这样的问题，在发送下行信号之前，向各ONU通知下行信号发送规划（下行光强度图）。每个ONU预先接收下游光强度图（下游信号的光强度传输调度）。因此，邻居ONU可以阻塞或衰减寻址到远程ONU的光信号，并且即使当远程ONU不能接收到寻址到相邻ONU的信号时，远程ONU也可以确定正常操作。因此，可以防止远程ONU发出错误的错误信号。

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： When an ONU accommodating range is enlarged, and ONUs shorter and ONUs longer in a communication path to an OLT are accommodated in a PON at the same time, there is a need to change a light intensity at the time of transmitting a downstream signal in order that both of the ONUs receive a downstream signal from the OLT. When a near-end ONU receives a signal having a light intensity necessary to communicate between the OLT and a far-end ONU, there arises such a problem that the light intensity is as high as an ONU receiver fails. In order to eliminate the ONU failure of the above problem, prior to transmission of the downstream signal, a downstream signal transmission schedule (downstream light intensity map) is notified to all of the ONUs. An optical transceiver of the OLT has a function of adjusting an output light intensity, and adjusts the light intensity to values receivable by the individual ONUs when the signal arrives at the respective ONUs according to route distances to the respective ONUs.

摘要： In a PON, at the time of ranging, an OLT (a master station) measures an optical level of a signal from at least an ONU (a slave station) capable of communicating at plural transmission speeds. The OLT determines the transmission speed applied to the ONU according to the measured level. Incidentally, the ONU may measure an optical level of a ranging request signal and determine the transmission speed. At a normal operation, when the OLT sends information of plural different transmission speeds to the ONU, a timing when a next frame reaches and transmission speed information are notified to the ONU. Based on the timing, the ONU receives only data of the transmission speed that can be handled. Besides, the OLT switches the transmission speed to receive data based on a grant designation transmitted from the plural ONUs to the OLT.

摘要： When data is disclosed to a plurality of users by using a transfer network and a transfer apparatus, data disclosure time control which cannot be adversely affected by the users is performed to reduce the difference in data disclosure time among the users. A transfer network system includes a distribution server serving as a data-distribution-source transfer apparatus, and a network terminal connected to distribution-destination user equipment. The distribution server and the network terminal each have a time keeping function and a time synchronization function for matching the time of the time keeping function with a master clock. The distribution server sends in advance disclosure data and disclosure time to the network terminal. When the time of the time keeping function of the network terminal matches the disclosure time, the network terminal sends the disclosure data to the user equipment.

The network management system includes a plane management table adapted to manage transmission planes defined as a set of paths in the transmission network, and the plane management table has the function to set and manage a transmission plane (working plane) applied during normal operation and besides, a single or a plurality of transmission planes (protection planes) applicable in the event of occurrence of a fault in the transmission network. Then, when a fault occurs in the transmission network, the network management system changes the applied plane to a suitable transmission plane.

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).
