Why do we call these things modems anyway? Isn't the 5366TN really a gateway/router? I don't think it's doing any modulating/demodulating, wouldn't the incoming signal be digital already?
@juzdu my guess would be for ease of referencing. You are right, for most people the 5366 would the router and/or a wireless acess point. In someway there is the modulation and demodulation of the VOIP function in the unit. It is also support ADSL connections, working as a Modem. I could be wrong, it also supports FTTC, which is like a pseudo ADSL, working as a modem.
No Darren, sorry, wasn't having a go at you at all, was just a random musing.
Is there something holding you to Optus? You sound really angry...might be time to try someone else given NBN is pretty switchable. I recently came back to Optus after using Kogan for NBN...I was an Optus cable customer for nearly 20 years but Optus wouldn't give me a good NBN deal until I finally disconnected. So I was with Kogan for a month then switched back to Optus.
Mind you I'm so used to poor customer service these days I've become a bit immune to it, and learned how to play the game a lot better.
