Abstract
A method and apparatus to determine performance of a subscriber loop includes using a database containing information pertaining to physical characteristics of a subscriber loop (or group of subscriber loops). Based on the information, a data communications speed of the subscriber loop is estimated. An actual data communications speed of the subscriber loop is determined and compared to the estimated data communications speed. The information in the database is updated based on the comparison.
Claims27
A method of determining communications channel performance, comprising:
- calculating a data communications speed of the communications channel based on records, used for high-speed access qualification;
- determining an actual data communications speed of the communications channel;
- and
- comparing the calculated data communications speed and the actual data communications speed to determine if the records are accurate.
An article comprising at least one storage medium containing instructions that when executed cause one or more systems to:
- access records pertaining to characteristics of a communications channel;
- determine variance between a predicted data communications speed of the communications channel based on the records and an actual data communications speed of the communications channel;
- and
- update the records based on the determined variance.
A system comprising:
- an interface adapted to access records pertaining to characteristics of a communications channel;
- and
- a controller adapted to receive an estimated bandwidth of the communications channel that is calculated based on the records;
- the controller adapted to receive an indication of an actual bandwidth of the communications channel;
- the controller adapted to update the records to reduce a variance between the calculated bandwidth and the estimated bandwidth.
