I can see your NBN-FTTC 50/20 install is progressing.
You need to do some of the install yourself.
You will need to UNPLUG ALL exisitng phones/modems, and setup the new NCD + MODEM to the socket.
Pay attention to the 4x blue lights on the NCD once completed. If you dont get the first 3x lights solid, let me know.
You may check the setup guide that we've created for NBN-FTTC here.
