Embodiment Construction
[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0032] Apply the GPON system composition of the present invention as figure 1 As shown, the optical line terminal (OLT) 11 is connected to several optical network terminals (ONT) 13 in the optical branching network through the optical splitter 12, and the corresponding PLOAM data paths are respectively established with the OLT after the optical network terminal 13 is powered on, and Receive the PLOAM message sent by the OLT, activate and register the optical network terminal (ONT) 13 through the PLOAM message and establish a corresponding OMCI data path. After the OMCI data path is established, the optical line terminal 11 can send downlink OMCI messages to the optical...

The invention discloses a method for analyzing, debugging and simulating the OMCI (Management and Control Interface) information and the PLOAM (Physical Layer Operation Administration and Maintenance) information of a GPON (Gigabit-Capable Passive Optical Network), comprising the following steps that: an A10 and each ONT (Optical Network Terminal) respectively package the received OMCI information and PLOAM information which are sent by an OLT (Optical Line Terminal) into Ethernet data packets of different types; an A20 and a debugging terminal capture all the Ethernet data packets sent from an Ethernet port through the Ethernet port of the ONT; an A30 and the debugging terminal obtains the Ethernet data packets with the OMCI information and the PLOAM information through filtering, respectively analyzing the contents of the OMCI information and the PLOAM information from the Ethernet data packets, and displaying the contents of the OMCI information and the PLOAM information as required, or reorganizing the contents of the OMCI information and the PLOAM information into new OMCI information or PLOAM information, and replying to the OLT through the ONT. The invention solves the problem of more difficult lookup of the OMCI information and the PLOAM information in the testing and engineering application of the GPON.
Description
technical field [0001] The invention relates to a GPON access network, in particular to a method for analyzing, debugging and simulating GPON system OMCI and PLOAM messages. Background technique [0002] GPON (Gigabit-Capable PON) technology is the latest generation of broadband passive optical integrated access technology based on the ITU-TG.984.x standard. It has many advantages such as high bandwidth, high efficiency, large coverage, and rich user interfaces. Most operators regard it as an ideal technology to achieve broadband and comprehensive transformation of access network services. Compared with other PON technologies, the main advantages of GPON are as follows: [0003] (1) It provides unprecedented high bandwidth, the downlink rate is as high as 2.5Gbit / s, and its asymmetrical characteristics are more suitable for the broadband data service market. [0004] (2) Provide full service guarantee of QoS, carry ATM cells and (or) GEM frames at the same time, have good ...
