Hi all

 

I've recently had residential fibre installed by Chorus. (Not because I need it, but for future-proofing.) They have fitted a Nokia G-140WC. It seems ideal as a small residential gateway, all I need. But, I am told that despite this in NZ I require a downstream modem. Please tell me why, using the least number of acronyms!

Hi I think you are referring to the fact the ont appears to be an all in one unit that includes the residential router.

Well it does, how ever for mainly logistical reasons no RSP will use it, it's far less hassle for them to provide you a separate downstream router.

On the modem terminology, technically the ONT is the modem, the modulator, demodulator aspect of the term modem in this case being the translation of gpon encoded light waves to electrical ethernet signals, a seperate router is required to provide you a local LAN.

The answer has been explained in this thread multiple times. Or to sum up, BECAUSE. And the response to your WHY?, is yes the Gen3 ont can do it all, but in NZ that's simply not the way the industry uses it, so you will need an extra piece of kit, a Router, that's it, nothing further to know.
