    • A Gigabit- capable Passive Optical Network (GPON), including an enhanced Optical Line Termination (OLT) and Optical Network Units (ONUs), provides enhanced features, e.g., features defined in XG-PON. One or more of the ONUs are enhanced ONUs. The enhanced OLT communicates with the ONUs via downstream frames and upstream bursts, each downstream frame and upstream burst being compliant with a GPON framing format. The enhanced OLT transmits downstream frames to the ONUs, the downstream frames including downstream sub-frames with at least one downstream sub-frame being an overhead sub-frame that includes information of the enhanced features. The enhanced OLT receives upstream bursts from the ONUs, the upstream bursts including upstream sub-frames, each upstream sub-frame including an upstream identifier field that indicates to the enhanced OLT whether the upstream sub-frame is an overhead sub-frame. The enhanced OLT and the enhanced ONUs perform network operations to provide the enhanced features specified in the overhead sub-frame.
    • 包括增强型光线路终端(OLT)和光网络单元(ONU)的包括千兆比特能量的无源光网络(GPON)提供了增强的特性,例如在XG-PON中定义的特性。 一个或多个ONU是增强型ONU。 增强型OLT通过下行帧和上行突发与ONU进行通信,每个下行帧和上行突发符合GPON成帧格式。 增强型OLT将下行帧传输到ONU,下行帧包括具有至少一个下行子帧的下行子帧,该至少一个下行子帧是包括增强特征的信息的开销子帧。 增强型OLT从ONU接收上行突发,上行突发包括上行子帧,每个上行子帧包括上行识别符字段,该字段向增强型OLT指示上行子帧是否是开销子帧。 增强型OLT和增强型ONU执行网络操作,以提供开销子帧中指定的增强功能。

    • A system, method, and node for efficiently packing payload of variable or arbitrary frame lengths into a TDM telecommunications system transmission. A transmitting unit transmits a plurality of frames w hose concatenation does not precisely fit into the interval between TDM framing synchronisation patterns to a receiving unit An offset value is determined, which specifies the consequent delay in transmission of a TDM framing synchronization pattern. The offset value is then sent to the receiving unit in conjunction with the TDM framing signal. The receiving unit receives the plurality of frames and the offset value and reconstructs a precise reference instant derived front the offset value By reconstructing the precise interval boundary, the receiving unit remains synchronised with the transmitting unit.

    • A system provides multidimensional tuple Hilbert ordering within a linear storage structure to enable more consistent and efficient access to stored multidimensional tuples. The database system comprises a tuple storage module that receives multidimensional data elements, where each multidimensional data element is defined by a plurality of different object types, and where each object is associated with a different dimension within a multidimensional data space. The tuple storage module further forms a respective tuple for each of the multidimensional data elements by mapping each object to an associated reference and applies a Hilbert function to the references of each of the tuples to determine a respective Hilbert ordering for each of the tuples. The system further comprises a linear data storage structure that includes a B-tree for storing the Hilbert ordering.
    • 系统在线性存储结构中提供多维元组希尔伯特(Hilbert)元组排序,以便更加一致和有效地访问存储的多维元组。 数据库系统包括接收多维数据元素的元组存储模块,其中每个多维数据元素由多个不同对象类型定义,并且其中每个对象与多维数据空间内的不同维度相关联。 元组存储模块还通过将每个对象映射到相关联的引用来为每个多维数据元素形成相应的元组,并将希尔伯特函数应用于每个元组的引用,以确定每个元组的相应希尔伯特顺序。 该系统还包括线性数据存储结构,其包括用于存储希尔伯特(Hilbert)顺序的B树。
