摘要： A management device (100) for use in an access network (10, 19, 20, 30, 40, 100) including a plurality of data connections (18, 19, 20) between end user devices (10) and an aggregation transceiver device (20) where the connections (18, 19, 20) are aggregated for onward connection through the access network (20, 30,40), 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 comprises 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 resynchronisations 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.

摘要： A method of provisioning an interface device (40), the interface device 40 interfacing between an access network (19, 20 30) and a back-bone network (50), the access network including a Digital Subscriber Line, DSL, connection (16, 18, 19, 20) to an end user (terminal 14) and a transceiver device (20) including a DSL transceiver for modulating and demodulating signals sent to and from the end user terminal (14) over the DSL connection, the arrangement of the network apparatus being such that data from a device (62) connected to the back-bone network (50) which is destined for the end user terminal (14) passes through the interface device (40) and then through the access network (30) and wherein the interface device (40) is operable to constrain the rate of flow of data from the backbone network (50) through the interface device (40) towards the end user terminal (14) to a predetermined maximum rate specified for the end user terminal (14). The method comprises: providing a management device (100) for managing the interface device (40); receiving data readings from the transceiver device (20) indicative of the current or recent line rate of the DSL connection; and provisioning the interface device (40) to restrict data flowing to the DSL connection to a new maximum rate selected by the management device (100) in accordance with the received data readings from the transceiver device (20) indicative of the current or recent line rate of the DSL connection, wherein, when the new maximum rate is greater than the existing maximum rate for the DSL connection at which the interface device (40) is currently provisioned, the interface device (40) is provisioned (or re-provisioned) only after a delay period, and wherein the delay period depends upon the amount of the increase in the new maximum rate compared to the existing maximum rate, and wherein, the greater the increase, the shorter the delay period.

摘要： In a method and system for operating an ADSL access network which has a plurality of data connections 19 between the access network and end user devices 10, and in which the access network controls the rate at which data is transferred between the user devices and an onward connection 50, the access network stores a plurality of capped profiles each of which specifies a respective upper data rate to which the connection is limited and which is below the maximum achievable rate for the connection. The access network operates using a Dynamic Line Management (DLM) algorithm which, for a given data connection, operates to enable data transfer at a variable data rate up to the maximum rate, monitors the error performance and signal to noise margin variation for different data rates and, in the event that one or both are outside respective limits for a predetermined period, selects and applies one of the capped profiles to limit the upper data rate, selection being determined by the highest data rate achieved for which the error performance was within acceptable limits.
