摘要： A method and apparatus in which a data stream generated by a previous network node, a cumulative phase offset report (CPOR) and a client rate report (CRR) are received. A counter accumulating a PHY-scaled stream clock (IPSCk) is sampled at a nominal sampling period (Tps) to obtain a cumulative PHY-scaled count (CPSC). A PHY-scaled stream phase offset (PSPO) is calculated that indicates phase difference between a PHY-scaled stream nominal bit count (LPSD) and an incoming PHY-scaled count delta (IPSD), where IPSD indicates CPSC increment between successive CPSC samples. The data stream is demultiplexed to obtain CBR carrier streams that include a previous network node CPOR (CPOR-P) and a previous network node CPO (CPO-P). A CPO is calculated that is a function of CPO-P and the PSPO. CPO-P is replaced with the calculated CPO. The CBR carrier streams are multiplexed into intermediate-network-node data streams that are transmitted from the intermediate-network-node.

摘要： Certain features relate to improving the link-fault tolerance in a distributed antenna system (DAS) by utilizing a series of synchronous communication frames. A receiving remote unit or a head-end unit in the DAS can predict the start of incoming communication frames based on frame information extracted from previously received communication frames. For example, a remote unit can be configured to receive one or more communication frames, each of the one or more communication frames including a start-of-frame field. After a period of time corresponding to the frame repetition rate, the remote unit can search for an additional start-of-frame field, indicating the receipt of the next communication frame. The remote unit can extract the payload data from the next communication frame based on the predicted value for the additional start-of-frame field.

摘要： A cell processing method and apparatus are provided. The method includes: obtaining, by a first sending end, a first timestamp compensation time; adding, by the first sending end, the first timestamp compensation time to a first timestamp carried in a first cell, where the first timestamp is a sending time of the first cell; and sending, by the first sending end to a receiving end, the first cell that is added with the first timestamp compensation time, so that the receiving end forwards the first cell according to the first timestamp that is added with the first timestamp compensation time. In the present invention, a first timestamp compensation time is added to a first timestamp carried in a first cell, which improves cell forwarding efficiency of the receiving end and prevents the occurrence of cell accumulation in a link.

摘要： The present invention relates to computing apparatus as an element of a network structure using a method for acquiring and maintaining cell locked data transfer amongst a number of computing apparatuses which can be full mesh interconnected by full duplex data transfer links. A predefined number of symbols transmitted as a cell is followed by a variable number of idle symbols to ensure the nominally simultaneous start of the cell transfers throughout the network without a central control. At specific positions of the cells each computing apparatus broadcasts a list of its transmission requests and receiver capabilities to all other computing apparatuses. Each of the interconnected computing apparatuses executes the same arbitration procedure based on the identical data set of transmission requests and receiver capabilities. As a result transmission paths are assigned for direct transmission and for payload forwarding. The transmission paths can be assigned per cell period individually for both directions of each link. Several packet protocols assigned over the cell transmission layer can coexist in the network.

摘要： Certain features relate to improving the link-fault tolerance in a distributed antenna system (DAS) by utilizing a series of synchronous Ethernet frames. A receiving remote unit or a head-end unit in the DAS can predict the start of incoming Ethernet frames based on frame information extracted from previously received Ethernet frames. For example, a remote unit can be configured to receive one or more Ethernet frames, each of the one or more Ethernet frames including a start-of-frame field. After a period of time corresponding to the frame repetition rate, the remote unit can search for an additional start-of-frame field, indicating the receipt of the next Ethernet frame. The remote unit can extract the payload data from the next Ethernet frame based on the predicted value for the additional start-of-frame field.

摘要： A communications system includes a physical layer device (PLD) and a logical link device (LLD), each having respective send and receive interfaces being substantially identical to define symmetrical interfaces for the system. Accordingly, design and manufacturing is simplified compared to conventional systems. In addition, advantages are also provided in terms of loopback capability and packaging options. The PLD comprises a PLD send interface including PLD parallel information outputs, and a PLD receive interface including PLD parallel information inputs. Similarly, the LLD comprises an LLD receive interface including LLD parallel information inputs, and an LLD send interface including LLD parallel information outputs. Parallel communications channels connect the PLD information outputs to respective LLD information inputs, and connect the LLD information outputs to respective PLD information inputs. The PLD send interface and the LLD send interface are substantially identical, and the PLD receive interface and the LLD receive interface are substantially identical to thereby define the symmetrical interfaces for the system. In view of the symmetrical interfaces, the PLD and the LLD may operate in a push-push configuration. Deskewing features are also provided.

摘要： In a method for terminating a plurality of ATM lines for a base station modulator/demodulator in a mobile communication system for data communication between upper stations and a base station by a transmission method wherein ATM cells are mapped utilizing an existing leased line as a physical medium sublayer, when an increase in capacity of the base station necessitates leased line interfaces corresponding to a plurality of upper stations, processing is carried out in such a manner that leased line numbers are added to respective HEC regions of ATM cells sent from each upper station into a leased line interface section, whereby the addition of the function of the leased line interface section involved in an increase in the leased line can be minimized and the additional function can be simply designed utilizing a conventional technique. By virtue of this constitution, a method for receiving a plurality of ATM lines can be realized which can efficiently utilize VCI filters and can distinguish each upper station in a leased line interface section.

摘要： A method of transmitting data includes synchronizing a system clock with a real time clock. Digital data is collected from multiple sources at a system clock time. A sample counter provides a count for each system clock time. The digital data for each source is associated with the count. A data cell is composed from the digital data associated with at least one count and a source identifier. A data frame is created from the data cells from every source. A cell frame is created from a plurality of data frames, and a time frame is composed from a plurality of cell frames. A heads-up cell including the count is transmitted before the time frame. A time/count cell including the count and the real time is transmitted with the associated time frame.

摘要： In a system having independently-clocked job-performing circuits (e.g., payload processors) and independently-clocked job-ordering circuits (e.g., request and payload suppliers), coordinating mechanisms are provided for coordinating exchanges between the independently-clocked circuits. The coordinating mechanisms include those that use transmitted time-stamps for scheduling contention-free performances within the job-performing circuits of requested jobs. The coordinating mechanisms additionally or alternatively include static and dynamic rate constraining means that are configured to prevent a faster-clocked one of the independently-clocked circuits from overwhelming a more slowly-clocked other of the independently-clocked circuits. In one implementation, independently-clocked telecommunication-shelves house a distributed set of line cards and switch cards. An asynchronous interconnect is provided between the independently-clocked shelves for carrying job requests and payload data between the distributed line cards and the distributed switch cards. The multi-shelf system is scalable and robust because additional or replacement line and switch cards may be inserted into one or another of the independently-clocked shelves as desired and because a unified clock-tree is not needed for synchronizing activities within the interconnected, but independently clocked shelves.
