TRANSMISSION APPARATUS AND TRANSMISSION METHOD

摘要

A transmission apparatus includes: a first input-output unit; a second input-output unit; a third input-output unit located in a first direction that is a transmission direction from the first input output unit and the second input-output unit; and a switch coupled to the first input-output unit, the second input-output unit, and the third input-output unit, wherein the first input-output unit requests the third input-output unit via the switch to notify in a second direction opposite to the first direction of a defect upon detecting the defect, wherein the third input-output unit transmits defect information indicating the defect to one of the first input-output unit and the second input-output unit via the switch in response to a requesting from the first input-output unit.
