Abstract
The subscriber loop forms the final link between the.subscriber and the actual . .telephone network.The pair of twisted copper wires which form the loop must be well maintained to avoid poor quality service to subscriber or customer.By conducting periodic testing of the subscriber loop, the telephone company .can .ensure the high standards of service that they desire.The purpose of this research project is to design a new loop tester based on a digital signal processing (DSP) chip, replacing the old analog-based testers.The DSP chip uses an analog-digital converter (ADC) to take sample measurements of various signals on the subscriberloop and a digital-analog converter (DAC) to output control signals.Various algorithms are.first analyzed and tested to verify their results for the tests required.Next, these .algorithmsare added to the software running on the DSP chip.The algorithms are then tested versus known input values to qualify the testing procedure and analysis for use on an actual subscriber loop.Finally, the software is used to provide test results of various fault conditions on a pair of twisted copper wires.The results from these tests show that the DSP-based loop tester can measure varying line resistance and capacitance due to faults present on the subscriber loop, which can lead to accurate fault analysis.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
