Abstract
The invention discloses a method used for adjusting a line rate, an apparatus and a system thereof. The method is characterized in that when an OLT carries out line rate adjusting, an adjusting instruction is sent to an ONU; when confirmation information sent by the ONU is received before adjusting initial time is up, the OLT adjusts a current line rate to a second line rate from a first line rate; if the rate can not be adjusted to the second line rate, the OLT rolls back to the first line rate; after the rate is adjusted to the second line rate, the OLT starts a first timer; if a rate adjusting success message sent by the ONU is received before the first timer expires, the OLT sends a success response message to the ONU so that the OLT uses the second line rate to interact with the ONU; and if the rate adjusting success message is not received when the first timer expires, the OLT rolls back to the first line rate. When an abnormity is generated, the OLT rolls back to the original line rate and work is performed so that equipment of both sides can interact normally after one-side line rate adjusting is failed, and continuity and stability of service bearing are guaranteed.
