Wireline Validation Engineer

Sample of Work

- Add an ONT to an existing PON and get it activated on the PON

- Log into the OLT and verify the ONT status, verify the configuration is good

- Check the light levels on both ONT and OLT, add attenuation as needed

- Add optics to the OLT and run a fiber to the upstream BNG to establish physical connectivity

- Set up the profiles on the BNG to dynamically add new subscribers

- Ensure the ONT is manageably by the NMS (ADTRAN AOE or Nokia AMS or similar management systems)

- Connect a Spirent Test Center 10G port to the ONT UNI

- Send DHCP traffic from the STC up the network

- Log into the BNG and check to see the subscriber status

- Track the DHCP server response to make sure the response was received by STC to establish a successful connection

- Set up multiple upstream and downstream traffic flows with varying sizes to test the network performance and scale

- Verify the traffic at different aggregation points in the network (ONT, OLT PON port, backplane, OLT uplink, BNG downlink, routing table etc.)

- Apply the necessary static route configuration on the BNG to establish management connectivity to the OLTs
