Abstract
A method, computer readable storage medium and apparatus for measuring data rates is disclosed. A method that incorporates the teachings of the present disclosure may include, for example, submitting a signal over a cable from a Time Domain Reflectometry (TDR) element, determining a fault in the cable from a reflection of the signal, determining a length of the cable from the reflection of the signal, determining a location of a bridged tap relative to customer premise equipment (CPE) and determining effective downstream bit rates for the cable according to the fault, the length of the cable and the location of the bridged tap relative to the CPE. Additional steps and embodiments are disclosed.
Claims15
A method, comprising:
- determining effective downstream and upstream bit rates of a cable according to a comparison of empirical measurements to a fault by submitting a signal over a cable using a Time Domain Reflectometer (TDR) element;
- and
- determining the fault in the cable from a reflection in the cable of the signal and according to a comparison of a length of a bridged tap and its relative location to customer premise equipment (CPE) with empirical measurements comprising attenuation factors indexed by the length of the bridged tap and its relative location to the CPE.
A non-transitory computer readable storage medium, the storage medium being embedded with computer instructions for causing a computing device to perform the steps of:
- submitting a signal over a cable using a Time Domain Reflectometer (TDR) element;
- determining a fault in the cable from a reflection of the signal and according to a comparison of a length of a bridged tap and its relative location to customer premise equipment (CPE) with empirical measurements comprising attenuation factors indexed by a length of a bridged tap and its relative location to the CPE;
- determining effective downstream bit rates of the cable according to a comparison of empirical measurements to a fault.
