Abstract: Technologies for robust data transmission include a network port logic having a physical coding sublayer (PCS). The PCS may transmit a series of rapid alignment markers (RAMs) to a link partner, with each RAM indicative of a counter value. The PCS transitions to a sleep state if the counter value equals two and a low power idle (LPI) command is set by an upper-layer client. The PCS transitions to an active state if the counter value equals one and the LPI command is not set. The PCS may receive a low power idle symbol (LI) from the link partner and start a guard timer in response to receipt of the LI symbol. The PCS transitions to a sleep state if the guard timer expires and transitions to the active state if data other than LI is received prior to expiration of the guard timer. Other embodiments are described and claimed.

In some aspects an indication of a packet type is provided with a page message to enable an access terminal to determine whether to receive the packet. In some aspects a local link interface may be selectively disabled or enabled to limit traffic at an access terminal.
