This read-write EnableAdmin object enables or disables bit-swapping, the ADSL mechanism that reallocates bits across subcarriers to compensate for changing line noise without retraining. An admin enables it on lines prone to impulse noise so the connection adapts in real time instead of dropping and resyncing. For example, on a line near a source of intermittent electrical interference, enabling bit-swapping avoids the multi-second resync that a full retrain would cause.
