Embodiment Construction

[0029] figure 1 It is a flowchart of a data synchronization method for an Ethernet passive optical network device according to an embodiment of the present invention, refer to figure 1 :

[0030] S11. After the OLT detects that the ONU is registered and online, before automatically sending the configuration parameters, it first sends a capability set query message;

[0031] S12. After receiving the capability set query message, the ONU reports the current capability set information to the OLT;

[0032] S13. According to the current capability set information of the ONU, the OLT selects the configuration parameters that match the current capability set information of the ONU from the configuration parameters to be delivered, and delivers it to the ONU.

[0033] figure 2 It is a flowchart of a data synchronization method for an Ethernet passive optical network device according to another embodiment of the present invention, please refer to figure 2 :

[0034] S21. After t...

Abstract

The invention discloses a data synchronization method and an optical line terminal of an Ethernet passive optical network device. The method includes that the optical line terminal obtains current capability set information of each optical network unit, according to the current capability set information of each optical network unit, the optical line terminal chooses a configuration parameter from configuration parameters to be issued and issues the chosen configuration parameter to each optical network unit, wherein the chosen configuration parameter is matched with the current capability set information of each optical network unit. Due to the technical scheme, the data synchronization method and the optical line terminal of the Ethernet passive optical network device is more perfect.

Description

technical field [0001] The invention relates to the field of EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network) equipment, in particular to a data synchronization method for Ethernet passive optical network equipment and an optical line terminal. Background technique [0002] Passive optical network has been widely deployed and applied in the access network. At present, after the OLT (Optical Line Terminal) in EPON is automatically issued, every time the ONU (Optical Network Unit) goes online, the OLT will automatically issue the Configure the parameters, and the OLT sends the configuration frames of all parameters to each ONU sequentially according to the configuration parameters saved locally to be delivered, and the ONUs respond in turn after receiving the corresponding configuration frames. Therefore, when there are many configuration items or the OLT downloads When there are many ONUs connected, the configuration time will be longer. Contents of...
