Embodiment Construction

[0015] The present invention will be further described below in combination with the principle diagram and specific operation embodiments.

[0016] The ONU type identification method of the present invention is applied to an OLT system. The OLT system includes an OLT and multiple ONUs. When the ONU goes online, a message is sent to the OLT. The OLT parses out the capability set information of the ONU from the message, where the capability set information includes All port types and port numbers of ONU. Here, ONUs with exactly the same port type and port number are considered to be the same ONU.

[0017] Combine all the port types and port numbers of the ONU in a fixed format to form the identification type of the ONU. The number of digits for the identification type of the ONU is 5 to 15 digits, and the number of digits can be deleted, and the meaning of each bit can also be used. Change accordingly.

[0018] Preferably 15 digits, please refer to figure 1 As shown, in the format o...

Abstract

The invention discloses a method for identifying ONU types, wherein the method is applied to an OLT system. The OLT system comprises an OLT and a plurality of ONUs. When on line, the ONUs can send a message to the OLT. The OLT analyzes the capability set information of the ONUs from the message, and the capability set information comprises all port types and the port quantity of the ONUs. The port types and the port quantity of the ONUs are combined according to a settled format to form the identifying type of the ONUs. The method can completely identify all types of the ONUs under the premise that the OLT system does not need to be upgraded and expanded, and the ONUs manufactured by different manufacturers can be used as long as being inserted into the OLT. In addition, by means of the method for identifying the ONU types, a user can clearly know the functions supported by the ONUs, and the user can configure and manage the ONUs conveniently.

Description

Technical field [0001] The invention relates to optical network technology, in particular to an ONU (optical network unit) type identification method. Background technique [0002] EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network) is a new type of optical fiber access network technology, which adopts a point-to-multipoint structure, passive optical fiber transmission, and provides multiple services on Ethernet. It uses PON technology at the physical layer, Ethernet protocol at the link layer, and uses the PON topology to achieve Ethernet access. A typical EPON system is composed of optical line terminal OLT (Optical Line Terminal), optical distribution node ODN (Optical Distribution Node) and optical network unit ONU (Optical Network Unit). The OLT is placed at the central office and is responsible for the connection, management and maintenance of the control channel. ODN is an FTTH optical cable network based on PON equipment, and its role is to provide...
