1. A physical-layer device, comprising:
- a first sublayer to receive a first continuous bitstream from a media-independent interface and to provide a second continuous bitstream to the media-independent interface; and
a second sublayer to transmit first signals corresponding to the first continuous bitstream during a first plurality of time windows and to receive second signals corresponding to the second continuous bitstream during a second plurality of time windows distinct from the first plurality of time windows, wherein the first sublayer comprises;
one or more layers to generate a third bitstream based on the first continuous bitstream; and
a time-division duplexing adapter to adapt a rate of the third bitstream and insert pad bits into the third bitstream in locations corresponding to times during which the second sublayer does not transmit the first signals, the times comprising the second plurality of time windows.

Abstract
A physical-layer device includes a first sublayer to receive a first continuous bitstream from a media-independent interface and to provide a second continuous bitstream to the media-independent interface. The physical-layer device also includes a second sublayer to transmit first signals corresponding to the first continuous bitstream onto an external link during a first plurality of time windows and to receive second signals corresponding to the second continuous bitstream from the external link during a second plurality of time windows. The second plurality of time windows is distinct from the first plurality of time windows.
