Patent number: 8462648Abstract: 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: January 22, 2008Date of Patent: June 11, 2013Assignee: British Telecommunications PLCInventors: Ashley Pickering, Trevor P Linney, Christopher M Croot, Philip A Everett, Gary J Dalby

Patent number: 8300528Abstract: Providing an interface device interfacing between an access network and a back-bone network comprises: providing a management device, receiving data readings from a transceiver device indicative of the current or recent line rate of a DSL connection of the access network, and providing the interface device to restrict data flowing to the DSL connection to a new maximum rate selected in accordance with the received data readings from the transceiver device indicative of the current or recent line rate of the DSL connection. When the new maximum rate is greater than the existing maximum rate for the DSL connection at which the interface device is currently provided, the interface device is provisioned (or re-provisioned) only after a delay period. The delay period depends upon the increase amount of in the new maximum rate compared to the existing maximum rate so that the greater the increase, the shorter the delay period.Type: GrantFiled: July 11, 2008Date of Patent: October 30, 2012Assignee: British Telecommunications public limited companyInventors: Philip Everett, Trevor Linney, Gary Dalby, Christopher M.
