Title: METHOD AND APPARATUS FOR OPERATING A TELECOMMUNICATIONS ACCESS NETWORK
Abstract:
An access network including twisted metallic pair connection to transmit data, including an access network modem connected to the twisted metallic pair connection and a broadband speed estimation tool including a web server and a line length, further deployment factors and speed determiner module. The web server to receive a deployment indication identifying a twisted metallic pair connection, an expected type of deployment and a type of DSL protocol of transmission. The line length, further deployment factors and speed determiner module is operable to determine, from the identification of the twisted metallic pair and the type of DSL protocol, an estimate of the length of the twisted metallic pair and, from the expected type of deployment, associated deployment factors, an estimated potential achievable data rate at which the DSL protocol can transmit data over the twisted metallic pair in dependence upon the determined estimate of the length and in dependence upon the determined associated deployment factors and the type of DSL protocol. The access network comprises a line management subsystem which determines an appropriate value for each configuration parameters in dependence upon the estimated data rate and causes the modem to operate in accordance with the determined values of the configuration parameters.
