| 20090175199 | Arrangement and Method of Configuring Digital Subscriber Lines - An arrangement, method, and node for configuring subscriber lines in a digital access network. A configuration tool downloads configuration parameters from the network into the access nodes, which configure the subscriber lines according to the configuration parameters. An automated monitoring tool monitors performance parameters for the subscriber lines. The monitoring tool compares a value of a first monitored performance parameter on each subscriber line with a predefined threshold value, and based on a result of the comparison, either changes a value of a first configuration parameter or repeats the monitoring of the first performance parameter. | 07-09-2009 |
| 20100017836 | Method and Device for Stream Adaptation - A stream adaptation device and method of adapting source data streams to the attainable transmission rate of a bandwidth-limited channel such as a Digital Subscriber Line (DSL). A plurality of transcoding units each receive a source stream at a given rate and transcode the stream into a plurality of transcoded streams of lower transmission rates. A polling unit retrieves the current quality of the DSL line from an IPDSLAM to which the DSL line is connected. A controller calculates the rates to be used on the DSL line for the different source streams. A selector then selects a combination of an original source stream and/or transcoded streams of lesser rates that fits the quality of the DSL line. A multiplexer combines the selected source streams and/or transcoded streams onto the DSL line. | 01-21-2010 |

| 20100189433 | SYSTEM AND METHOD FOR LONG BACKHAUL LINK EXTENSION IN A PASSIVE OPTICAL NETWORK - A system and method of extending a trunk reach of a passive optical network, PON. An optical network termination, ONT, processes upstream and downstream PON signals on a trunk fiber with an optical line termination, OLT, at a central office. An extender device may be implemented at a user's home, a remote node, or at the central office. The extender device includes a time division multiplexing, TDM, unit for multiplexing the PON signals, a forward error correction, FEC1 unit for applying an FEC to the PON signals, and a regenerator for applying optical-electrical-optical, OEO, regeneration to the PON signals. | 07-29-2010 |
| 20100235432 | Distributed Server Network for Providing Triple and Play Services to End Users - A distributed server framework for distributing streamed electronic content to users. The framework includes a central server connected to regional edge servers, which are connected to local groups of access servers closest to the users. A file sharing protocol maintains hit lists indicating the relative popularity of various content. To reduce the traffic load from the central server and regional servers, popular material is stored on the access servers; less popular material is stored on the edge servers; and seldom requested material is stored on the central server. A sliding window and cursor mechanism enable smart distribution of hot material and breaking news among the access servers. | 09-16-2010 |
| 20100310255 | Remote powering for FTTX via existing wire - The present invention relates to a powering method, a powering system, a cabinet and a central office for powering a copper-centric fiber to the x (FTTX) architecture. The architecture comprises at least one point to point or point to multipoint optical distribution network (ODN) between an optical line termination (OLT) or first Ethernet Switch positioned at a central office (CO) and an optical network unit or second Ethernet switch positioned at a cabinet (CAB) or building closer to a network terminal (CPE). The ODN is an active or passive network. The architecture further comprises at least one signalling coaxial or twisted wire pair line between the ONU or second Ethernet switch (ES) and one network terminal (CPE). What particularly characterizes the present invention is that the ONU or the second ES is powered remotely from the central office (CO) via at least one powering twisted wire pair line extending between the central office (CO) and the cabinet (CAB) or building. | 12-09-2010 |

| 20120020668 | Method And An Interconnecting Node For Use In An Access Network - The invention relates to an interconnecting node for use in interconnecting a passive optical network (PON) and a copper wire xDSL access network, wherein said interconnecting node comprises an optical network unit (ONU) arranged to be connected to an optical line termination (OLT) over the PON network; and at least one xDSL access device connectable to at least one user end xDSL equipment over the copper wire xDSL access network. The interconnecting node is characterized in thatit further comprises a clocking interconnect between the ONU unit and the at least one xDSL access device arranged to distribute a clock signal obtained from optical network transmissions received in the ONU unit over the PON network to an timing reference input of the at least one xDSL access device. The invention also relates to a further interconnecting node, methods for use in interconnecting nodes, a central office optical network apparatus and an access network. | 01-26-2012 |
