Abstract: Currently, under bitstream access, communications providers are only given limited control over the services they offer. In order to prevent customers being accidently or maliciously reconfigured by a competitor, each communications provider's circuit is isolated from the other communications providers, and dynamic line management profile choice is maintained by the network operator. The present invention proposes allowing greater access to communications providers to configure physical layer configuration parameters associated with a line, through the use of an adaptation gateway. The adaptation gateway is used to manage configuration requests to digital subscriber lines from the communications providers. The adaptation gateway allows configuration of certain DSL line, channel or data path parameters (such as those listed in ITU-T Recommendation G.997.1), but prevents modification to any of those parameters that might affect or cause harm to the service of another line.

Abstract: An access network comprises a plurality of access nodes (DSLAMs), a plurality of network access servers (CP BRASs) and an ANCP relay. The access network control relay component relays data between an access node and a plurality of network access servers and includes one or more interfaces and associated functionality in an ANCP listener component for enabling a connection between the relay component and the access node, for transmitting data and/or messages thereover, and an interface (ANCP Agents) for a connection to be made with each of the plurality of network access servers (via ANCP listeners contained within the BRASs) for transmitting ANCP messages thereover; and a mapping database for storing mapping data to determine to which network access server a message should be transmitted from the relay component, together with a CP authentication database and a workflow processing component for controlling operation of components within the ANCP relay.

Abstract: 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.

Abstract: 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.

Abstract: 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 which performs dynamic line management based on the data.
