Patent number: 10516581Abstract: 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.Type: GrantFiled: March 27, 2014Date of Patent: December 24, 2019Assignee: BRITISH TELECOMMUNICATIONS public limited companyInventors: Christopher Marcus Croot, Trevor Philip Linney

Patent number: 9166871Abstract: 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.Type: GrantFiled: February 5, 2013Date of Patent: October 20, 2015Assignee: British Telecommunications PLCInventors: Ashley Pickering, Trevor Philip Linney, Christopher Marcus Croot, Philip Anthony Everett, Gary John Dalby
