Problems solved by technology

The agreement stipulates that when the ONU receives the ONU-ID issued by the OLT, it will enter the O4 state from O3, but it does not stipulate the action and state transition of the ONU when the equipment serial number authentication fails.

Embodiment Construction

[0022] A method for processing illegal optical network units by a GPON system according to the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 2 As shown, a deactivation process of a method for processing an illegal optical network unit by a GPON system includes the following steps:

[0024] In step 1, the OLT sends to the ONU an effective DS frame with a downstream frame synchronization signal PSYNC (Physical Synchronization) used for synchronization between the ONU and the OLT, and uses this signal to synchronize the OLT and the ONU. At this time, the ONU is in the O1 state, which is the initial state.

[0025] In step 2, the OLT sends a PLOAM message (upstream-overhead PLOAM) carrying an upstream overhead parameter indication to the ONU. The PLOAM message is defined by ITU-T G.984.3. At this time, the ONU is in the O2 state, that is, the standby state.

[0026] Step...

Abstract

The invention provides a method for processing an illegal optical network unit (ONU) by a GPON system, comprising the following steps: firstly, the ONU reports an equipment serial number of the ONU to an OLT; secondly, a detecting device detects the received equipment serial number, if the equipment serial number is illegal, the detecting device records the equipment serial number, and the OLT sends a message of entering into an emergency stopping state to the ONU. The invention makes up the blank of a GPON protocol, provides a method for reasonably processing the illegal ONU under the condition that the equipment serial number of the ONU does not pass the authentification and provides the condition of the action and the state of the ONU.

Description

technical field [0001] The invention relates to a method for processing an optical network unit (ONU), in particular to a method for processing an illegal optical network unit by a GPON system. Background technique [0002] GPON is a broadband passive optical access technology proposed by ITU-T (International Telecommunication Union Telecommunication Standardization Bureau). The GPON system generally consists of an OLT (Optical Line Termination, Optical Line Termination) at the central office, an ONU (Optical Network Unit, Optical Network Unit) at the user end, and an ODN (Optical Distribution Network). A point-to-multipoint network topology is adopted between the OLT and the ONU, such as figure 1 shown. [0003] According to the GPON protocol, when the ONU is connected to the GPON system, it will report its equipment serial number to the OLT (if the OLT requires a password, it should also report the password) for equipment authentication. If the authentication passes, the...
