    摘要: An interconnection between fully synchronous networks and next-generation frame communications networks is disclosed. A means of bidirectional frame format conversion between a synchronous multiplexing system and a logical multiplexing system is provided, along with a method of transmitting data between different networks on a path as if it were being transmitted in the same network. Further, when converting network control information in an STM network into data suitable for a packet network, even across the boundary of a synchronous multiplexing system and a logical multiplexing system, a unified communication management means is provided over the whole path.

    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: A transmission device uses transmission delay time of reciprocation with the terminal and time information of the transmission device to create a correction value of time information of the terminal and transmits it to the terminal. The terminal includes expected arrival time information based on the time information of the terminal and the correction value received from the transmission device in a frame transmitted to the transmission device. The transmission device compares reception time of the frame with the expected arrival time information in the frame. If they match, the time information of the terminal synchronizes with the time information of the transmission device. If they do not match, the transmission device transmits a new correction value to the terminal. The terminal transmits a frame including expected arrival time information using the new correction value to the transmission device.

    摘要: For a user signal (signal requesting for provision of services) input to a signal transport network, header information for transmission in the signal transport network is given at a portal edge of the signal transport network on the user side. The information given at this time includes a time stamp indicating the time of receiving the user signal by the edge. In a server on the service provider side, the time stamp is referred to, and services are provided for each user. Specifically, a response process schedule for each user is produced from the time stamp, and waiting time is reduced and a priority process is performed in accordance with the time of issuing the request by the user.

    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: An optical communication system has a master station and a plurality of slave stations connected thereto via an optical fiber network, which is provided with an optical splitter and a relay unit which relays signals transmitted/received between the master station and the plurality of slave stations. The master station includes a first controller for performing ranging between the master station and the relay unit, and the relay unit includes a second controller for performing ranging between the relay unit and the plurality of slave stations. The master station determines, on the basis of the results of ranging performed by the first and second controllers as well as reports from the slave stations, timings for the slave stations to transmit signals to the master station, and receives signals multiplexed through the optical fiber network from the slave stations.

    摘要: Communication time period measuring frames are simultaneously sent from an OAM adaptive device on a transmission side, to both a working path and a protection path. In an OAM adaptive device on a reception side, reception times of the frames having arrived from both the paths are checked so as to measure a time period difference between both the paths. The time period difference is fed back to a logic distance adjustment function of each PON section to determine required communication time periods of the PON sections respectively included in a working system and a protection system. Communication time periods of the working system and the protection system in a packet communication network are arbitrated in order to decrease a packet loss at line switching in a packet relaying network.
