Abstract

The method includes obtaining a loop length of a terminal section of the communication line; determining whether there is an impairment in the communication line; if no impairment, classifying the communication line into the first group; if impairment is determined, perform obtaining a location of the impairment in the communication line; determining whether the impairment is located in the terminal section of the communication line based on the loop length; if so, classifying the communication line into a second group; else, classifying the communication line into the first group; wherein, in the first group, it is qualified for an new broadband communication service, and if in the second group, it is not qualified, and wherein, the new broadband communication service is to be deployed over the terminal section of the communication line.

Claims13

Dependent claims

A method of evaluating a communication line in a digital subscriber line (DSL) network, the communication line connecting an access node and an end-user customer-premise equipment (CPE) method comprising:

obtaining a loop length of a terminal section of the communication line, the terminal section of the communication line being between the end-user CPE and a potential insertion point of a fiber;
determining whether there is an impairment in the communication line;
classifying the communication line into a first group in response to a determination that there is no impairment in the communication line;
and
in response to a determination that there is an impairment in the communication line,
obtaining a location of the impairment in the communication line,
determining whether the impairment is located in the terminal section of the communication line based on the loop length,
classifying the communication line into a second group in response to a determination that the impairment is located in the terminal section of the communication line, and
classifying the communication line into the first group in response to a determination that the impairment is not located in the terminal section of the communication line,
wherein, the first group is qualified for a new broadband communication service, and the second group is not qualified for the new broadband communication service, and
wherein, the new broadband communication service is to be deployed over the terminal section of the communication line.
