1. A system for automatically testing local loops of telecommunications networks, the system comprising:
one or more hardware processors configured by machine-readable instructions to:
obtain attenuation data collected by a computing device communicatively coupleable with a local loop of a telecommunications network, the attenuation data including a first attenuation value for a first tone carried by the local loop, the first attenuation value indicating attenuation for the first tone, and a second attenuation value for a second tone carried by the local loop, the second attenuation indicating attenuation for the second tone, wherein the local loop has a line type and a line length;
calculate a first attenuation threshold based on the line type, the line length, and a frequency of the first tone and calculate a second attenuation threshold based on the line type, the line length, and a frequency of the second tone, the first attenuation threshold indicating an allowable attenuation for the first tone for providing a service over the local loop and the second attenuation threshold indicated an allowable attenuation for the second tone for providing the service over the local loop; and
determine whether at least one of the first attenuation value exceeds the first attenuation threshold or the second attenuation value exceeds the second attenuation threshold.
