PPPoE Dialup Emulation

PPPoE Dialup Emulation

After enabling PPPoE dialup emulation, you can emulate PPPoE dialup on the ONT and locate faults.


  • The user is a user with the operator authority or higher.
  • The OLT and the NMS communicate with each other properly.
  • PPPoE users are configured on the BRAS.
  • The NMS is able to discover an online ONT and data of the Internet access service is configured.


Currently, the mainstream access mode of broadband users is PPPoE dialup. In this mode, all service packets are encapsulated in PPPoE packets and PPPoE dialup authentication is terminated on the BRAS. The ONT is usually deployed on the edge of a network and resides between PPPoE dialup users and the BRAS, connecting PPPoE users to the network.

With the PPPoE dialup emulation function enabled on the ONT, you can emulate PPPoE dialup for testing and report collected test results to the NMS server. After analyzing the test result on the NMS server, you can determine where a fault occurs, which is very useful for daily maintenance and troubleshooting.


  1. In the Main Topology, double-click the required OLT in the Physical Root navigation tree; or right-click the required OLT and choose NE Explorer from the shortcut menu.
  2. Choose GPON > GPON Management from the navigation tree.
  3. On the GPON ONU tab page, set the filter criteria or click to display the GPON ONUs.
  4. Select a record from the ONT list, right-click, and then choose Test > PPPoE Test.
  5. In the dialog box that is displayed, set the related PPPoE emulation parameters, as shown in the following figure.
