20120099424 | DYNAMIC LINE MANAGEMENT - A Digital Subscriber Line Access Multiplexor (DSLAM) for operation within an access network includes a plurality of digital subscriber line modems for terminating a plurality of corresponding digital subscriber lines and aggregating them for onward connection through the access network. The DSLAM is operable, each time a data connection is established or re-established over one of the digital subscriber lines, to generate line data about the data connection at the DSLAM, to store the line data, to wait a predetermined period of time, to determine if the data connection is still operating successfully since the establishment of the connection without having suffered loss of connection during the predetermined period and then to transmit the line data to a management device | 04-26-2012 |
20130215773 | DATA COMMUNICATION - A management device is used in an access network including a plurality of data connections between end user devices and an aggregation transceiver device where the connections are aggregated for onward connection through the access network. The access network stores a plurality of different profiles, each of which specifies a set of values for a plurality of parameters associated with each data connection. The device applies one of the stored profiles to each connection, and receives a notification in the event of one of a predetermined set of notifiable events occurring on the connection. It is determined if more than a predetermined number of notifications are received within a predetermined period for a respective connection and, in the event of such a determination being made, a different one of the profiles is caused to be applied to the connection. | 08-22-2013 |

20110191472 | DYNAMIC LINE MANAGEMENT - A management device for use in an access network including a plurality of data connections between end user devices and an aggregation transceiver device where the connections are aggregated for onward connection through the access network, the access network storing in association with each data connection a Dynamic Line Management, DLM, profile which specifies a set of values for a plurality of parameters associated with the respective data connection, together with a stability level specifying a desired level of stability for the data connection. The device includes means for receiving monitoring data specifying the stability of each respective data connection over a predetermined period of time; means for selecting a DLM profile to be applied to the connection in dependence on both the monitoring data and the stored stability level associated with the data connection; and means for requesting an OSS system of the access network to apply the selected profile to the data connection. The DLM profile selection means disregards any resynchronizations or errors estimated to have occurred as a result of an area wide event such as a thunderstorm. It performs this estimation by detecting a large number of retrains and or errors occurring within a predetermined short test period. | 08-04-2011 |

20140233724 | DIGITAL SUBSCRIBER LINE MANAGEMENT USING VIRTUAL NOISE CALCULATION - A digital subscriber line management system is provided. It comprises a device for calculating a set of values specifying a virtual noise mask. The device includes a receiver for receiving or otherwise obtaining a set of measurements of noise levels experienced at a digital subscriber line transceiver at each of a plurality of frequencies at different times, and a processor for calculating, in respect or each frequency, a combined value based on a plurality of measurements taken at different times, and for generating the set of values specifying a virtual noise mask in dependence upon the combined values. | 08-21-2014 |
