Abstract
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.
