Method and apparatus for transmission line testing

An apparatus comprising:

• a transmission line interface to connect to a transmission line;
• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the processor to perform operations comprising:
• applying, at a customer premises device, a test signal to the transmission line coupled to the customer premises device;
• measuring, at the customer premises device, a reflection of the test signal;
• determining whether the transmission line supports a transmission service based on the reflection of the test signal;
• and
• generating an output indicative of whether the transmission line supports the transmission service.

A processor-readable storage device storing instructions that, when executed by a processor, cause the processor to perform operations comprising:

• applying, at a customer premises device, a test signal to a transmission line coupled to the customer premises device;
• measuring, at the customer premises device, a reflection of the test signal;
• generating an estimated achievable data rate of the transmission line based on the reflection of the test signal;
• determining whether the transmission line supports a transmission service based on the estimated achievable data rate;
• generating an output indicative of whether the transmission line supports the transmission service;
• and
• after generating the output, enabling a computing device to send and receive digital signals via the transmission line.
