    摘要: A method for detecting a failure network terminal in a Passive Optical Network includes: changing timeslots assigned to potential failure network terminals one by one; and determining the failure network terminal according to uplink data frames sent by the potential failure network terminals whose timeslots are changed. Embodiments of the present invention also disclose an apparatus and system for detecting a failure network terminal. The solution of the present invention may detect which Optical Network Unit/Terminal (ONU/ONT) fails and perform the corresponding processing in accordance with embodiments of the present invention, which recovers the system health and improves the network security, stability and self-healing ability.

    摘要: This invention provides a method for upgrading the network rate of a Passive Optical Network (PON), which mainly includes: upgrading the optical fiber line rate of the central office device, and adapting, by the network terminal device, the working rate of the upstream/downstream line automatically to the optical fiber line rate of the central office device according to a downstream data flow transmitted from the central office device. Using the method of this invention, the network rate of the PON can be upgraded without replacing the network terminal and without a manual intervention.
