摘要： A communication system comprises a passive optical network (PON) having an optical line terminal (OLT) coupled to a plurality of optical network terminals (ONTs) through a power splitter. Each ONT is coupled to the power splitter via a subscriber line. A switch is coupled to each subscriber line, and all of the switches are coupled to a control element. A power element is configured to receive optical signals communicated by the PON and to convert the optical signals into electrical power for use by the control element. The OLT is configured to detect a rogue ONT and to communicate with the control element for opening the switch that is coupled to the subscriber line of the rogue ONT, thereby optically isolating the rogue ONT from the rest of the PON.

摘要： A telecommunications access module comprises at least one bonding engine that receives packet data and bonds subscriber line pairs together to form a bonding group over which packet fragments are transmitted. A database maintains a list of communications subscriber line pairs that form the bonding group. A processor is configured to determine whether an incoming packet subject to fragmentation is long enough to fragment across multiple subscriber line pairs. If the incoming packet can be fragmented, the processor is configured to calculate a cost function for minimum packet fragment sizes that is proportional to the end-of-fragment arrival time at the far end of each subscriber line pair and calculate remainders of packet fragment length. The packet is fragmented based on the calculated cost function and remainders of any packet fragment lengths and allocated to the subscriber line pairs and transmitted.

摘要： A system and method transmits data and receives data packets within a bonding engine. The data packets are fragmented into a plurality of packet fragments for communication across a bonded group of subscriber lines. A Frame Check Sequence (FCS) in the data packet is inverted on one direction of the bonding group to prevent any data packets from propagating towards the network during a loopback condition.
摘要翻译：系统和方法发送数据并在绑定引擎内接收数据包。数据分组被分段成多个分组片段，用于通过绑定的用户线路组进行通信。数据包中的帧校验序列（FCS）在绑定组的一个方向上被反转，以防止任何数据分组在环回条件期间向网络传播。
