I'm going to be making the move to NBN HFC, and have a few questions about how it will be setup. I am currently using the provided Optus cable modem router on bridge mode to a separate wireless router. My understanding is that a NBN modem will be provide, so that should just replace the Optus cable modem and I don't need to purchase any additional hardware. Is my understanding correct? Will the existing (Optus) coaxial outlet be used, or will the technician create a new outlet for the NBN connection? I assume the cutover to NBN will not coincide with when my monthly Optus plan rolls over to the next month. Will I get charged a pro-rata amount only for the month, or do I need to pony up for the whole month? If it is the latter, is it possible to have both connections available to test? I assume this would depend on my previous question as to whether a new outlet is created. Thank you in advance for your answers!
