Abstract
A first physical layer device includes a first transmitter and a first receiver. The first transmitter transmits first data to a second physical layer device over a medium at a first line rate during a first transmit period. The first receiver is configured to not receive data during the first transmit period and an echo reflection period occurring after the first transmit period. The echo reflection period is based on a length of the medium between the first physical layer device and the second physical layer device. The first receiver is configured to, after the echo reflection period, receive second data from the second physical layer device over the medium at a second line rate that is less than the first line rate.
Claims20
A first physical layer device, comprising:
- a first transmitter transmitting first data to a second physical layer device over a medium at a first line rate during a first transmit period;
- and
- a first receiver configured to:
- not receive data during the first transmit period and an echo reflection period occurring after the first transmit period,
- wherein the echo reflection period is based on a length of the medium between the first physical layer device and the second physical layer device;
- and
- after the echo reflection period, receive second data from the second physical layer device over the medium at a second line rate that is less than the first line rate.
A physical layer device, comprising:
- a first receiver receiving first data at a first line rate from a second physical layer device over a medium during a first receive period;
- and
- a first transmitter configured to:
- not transmit data during a first period, equal to one-half of an echo reflection period, after the first receive period,
- wherein the echo reflection period is based on a length of the medium between the first physical layer device and the second physical layer device;
- and
- after the first period, transmit second data to the second physical layer device over the medium at a second line rate that is less than the first line rate.
