Adaptive rate subscriber loop data transmission using Ethernet interfaces
Bibliographic record
Abstract
The increasing demand for Internet and World Wide Web access from the home has stimulated research into finding methods of providing access at rates greater than the 28.8 kb/s offered by current computer modems. Most copper telephone pairs have bandwidth capacities much greater than the 3.4 kHz voice-band. Using this excess bandwidth it is possible to substantially exceed current modem rates. This paper describes an inexpensive and readily deployable network access technology capable of providing bit rates ranging from hundreds of kb/s to potentially greater than 1 Mb/s on existing copper telephone lines. The usable bit rate, which varies depending on the length and gauge of the wire, is adaptively determined at system start up. The results of rate adaption testing are presented, as well as the results of throughput testing when TCP is used to provide flow control across the adaptive rate transmission line. It is also shown that current IBM compatible computers are only capable of supporting data rates of slightly more than 1 Mb/s through Ethernet adaptor cards; providing access rates beyond a few Mb/s is currently unnecessary.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
