摘要： An optical access system that sends packets in a given time slot more efficiently without wasting bandwidth. The uplink channel from slave devices to a master device is divided into time slots. The sending slave device reads out upstream packets from its send packet buffer when an assigned time slot comes. If the maximum frame size is reached in the middle of a packet, the slave device suspends further reading until a next assigned time slot comes. The packets are sent to the master device, each being set off by a start and end delimiters. Detection of a start delimiter causes the master device to begin writing each received data word into a receive packet buffer, which is terminated by the end delimiter of that packet. Received packets are retrieved from their memory locations specified by a read address that includes the sender's slave device number.
摘要翻译：光接入系统能够更有效地发送给定时隙中的报文，而不会浪费带宽。从从设备到主设备的上行信道分为时隙。当分配的时隙到来时，发送从设备从其发送分组缓冲区读出上行分组。如果在分组中间达到最大帧大小，则从设备将暂停进一步读取，直到下一个分配的时隙到来。这些数据包被发送到主设备，每个设备都由一个起始和终止分隔符来设置。起始分隔符的检测使得主设备开始将每个接收到的数据字写入接收分组缓冲器，接收分组缓冲器由该分组的结束分隔符终止。从包含发送方从设备编号的读取地址指定的存储单元检索接收到的数据包。

摘要： A communication system is provided for preventing delivery of unnecessary packets to a user terminal and thereby improving transmission efficiency. In the communication system, an OLT communication interface transfers packets between a local office and a subscriber or transmits filter-setting data and receives filter-state data. An ONU communication interface transfers packets between the local office and the subscriber or receives the filter-setting data and transmitting the filter-state data. A terminal address managing unit obtains and manages a terminal address from a connected terminal. A packet filter performs an operation of filtering packets transmitted from an optical line terminal with respect to the connected terminal on the basis of at least one of delivery information, registered information and the filter-setting data.

摘要： In a communication system comprising a network unit and a plurality of subscriber units connected to the network unit, the network unit generates a message in which validity of transmission grant information is set for the subscriber units, and suspends a transmission of polling information to allocate a transmission grant to the subscriber units by using the transmission grant information for a fixed time in consideration of a processing time of the subscriber units from a time when the message has been completely transmitted. Also, when a disconnection state of an inputted cell from the subscriber units is detected, the network unit may suspend an input disconnection detecting operation for a fixed time from a time when the message and the polling information have been completely transmitted. Furthermore, a switchover of an input disconnection detection/transmission grant information may be suspended by mutually exchanging messages.

摘要： A communication device capable of restraining the packet transmission efficiency from lowering. An address storing unit extracts, from uplink packets, the addresses of terminals connected to sub-units and registers the addresses in an address management table. An address extracting unit extracts the address of a destination terminal included in a downlink packet output from a layer 2 switch, and an address determining unit determines whether or not the address of the destination terminal is registered in the address management table. In accordance with the result of the determination, a packet output unit outputs the downlink packet to a corresponding coupler.
