Embodiment Construction

[0034] The present invention will be described in detail below with reference to the drawings and specific implementations of the specification.

[0035] The embodiment of the present invention provides a method for link loopback detection of a PON system, such as figure 1 As shown, the method includes the following steps:

[0036] Step 101. Open the network management interface, set the loopback link detection parameters, turn on the loopback detection function of the core switch disk, and send the first level detection message to each uplink port and the slot port of each service disk through the core switch disk. .

[0037] It should be noted that the Ethernet type in the first level detection message is set by the user. For example, the Ethernet type can be set to Oxeffa.

[0038] Step 102: The core switchboard judges whether the first-level detection message returned from another uplink port or slot port is received within a preset time, if yes, step 104 is executed; otherwise, s...

Abstract

The invention discloses a PON system link loopback detection method and device. A loopback detection function of a core switching disk is opened, and a primary detection message is sent to all upper connecting ports and slot position openings of all service disks respectively; detection is completed if the returned primary detection messages are not received; it is determined that loopback exists in a PON system if the returned primary detection messages are received; the detection is completed if loopback exists between the upper connecting ports; a loopback detection function of service board cards is opened if loopback exists between the upper connecting ports and the slot position openings or loopback exists between the slot position openings, each service board card respectively sends a secondary detection message to a specific ONU, and detection is completed if the service board cards do not receive the returned secondary detection messages; the service board cards and the specific ONU which produce the loopback are accurately positioned according to an ONU authorization number carried in the secondary detection messages and slot position numbers of the service board cards if the service board cards receive the returned secondary detection messages. By means of the PON system link loopback detection method and device, the implementation process is simple, detection results can be timely reported, and PON system link loopback detection efficiency is greatly improved.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for loopback detection of a PON system link. Background technique [0002] With the development of communication technology, users who access broadband become more and more common. Broadband access equipment is connected to the transmission convergence layer equipment on the network side, and the user side is connected to the user’s home gateway or DSL (Digital Subscriber Line) modem. The diversity and complexity of user access have caused the phenomenon of link loopback. For example, users often encounter problems such as not being able to access the Internet or making calls. These problems are mostly caused by the loopback in the system link. The packets coming in from the uplink port are returned to the equipment in some way after exiting the optical line terminal, such as in PON (Passive Optical Network, passive optical fiber). In the network) e...
