In accordance with teachings of the present disclosure, a method includes—at a network element communicatively coupled to a y-cable through two transmitters of the network element—transmitting data from a transmitter through the y-cable to a client and withholding transmission from the other transmitter, and determining whether receivers have received a backward defect indicator from the client. The method further includes determining that an interruption has occurred within a transmission media between the network element and the client, based on the determinations of whether the receivers have received the backward defect indicator from the client. The method also includes, based on the determination of the interruption, transmitting data from the other transmitter through the y-cable to the client and withholding transmission from the transmitter.
