I'm looking at potentially suitable locations for an ONT in the house, so that we can investigate our share of installation costs. 

Without boring you with details, it's not going to be a standard simple install. Due to alck of data cabling, limited power points and reliance on WiFi in important areas of the house ONT location will need to be quite some distance from the ETP.  We will probably have to pay for extra fibre. 

I'd like to be forearmed with a few location options to discuss with install tech.

I've read the chorus guidelines for new home wiring, which includes a section detailing size and physical requirements for a star-wire box.  This doesn't provide any indication of temperature requirements or airflow e.g could I stick it in a hot water cupboard?

It would also be useful to know how much noise and heat an ONT produces.  As the TV area in the lounge may be an option

Anyone have this info?

The ONT from Chorus (Alcatel), Enable/UFF (Huawei) or NorthPower (Erricson) are all boxes that don't have fans so are completely silent.

In regards to heat, as long as it's not too hot then it should be fine.

Typically behind the TV is a common place to install the ONT as that is the "media hub" of the house. Otherwise in the computer room or wherever else is appropriate for the ONT to have the ISPs Router plugged into the ONT.

Hi Mike,

The Chorus ONT doesn't generate noise (there are no fans).
A hot water cupboard is definitely not suitable (neither is a ceiling cavity).

Some of the requirements we give the installers are:
- attached to a wall stud
- minimum 300mm from the floor to the bottom of the ONT
- dry location with good ventilation

 

I can't remember these off the top of my head, but you should allow ~200mm clearance around and the ONT (I think the sides might be slightly less, but 200mm is a safe bet.) let me know if 
you really, really need the exact info and I can go find it.

Operating temp is around 0deg to 40deg ambient.

Thanks,
Brent

Thanks for the advice.  Our office cupboard might work: -
- It's sizable.
- It's cool.
- Fibre/power/phone/data can be run down into the top of it from the roof space.  
- The phone cable (?Cat5?) runs directly above it (don't know if that matters).

Cat 6 cables run from the office to the lounge and bedroom.  If I have each cable cut at the cupboard and terminate the new ends into a four outlet plate in the cupboard ceiling I will end up with the following CAt6 cables: -
- Cupboard to lounge
- Cupboard to bedroom
- 2 x Cupboard to office

If I install the RGW in the cupboard too it can become a little hub.  

The catch is the fibre would have to go up the side of the house (2 levels) into the roof space and along to the office cupboard. It's cavity construction with foam/stucco outer cladding and still under warranty so new holes in the wall are a non-starter.  

There is an existing phone line from the ETP into the roof space, so maybe that could be used to draw the fibre up into the roof?

Probably 15m of fibre from the ETP to the cupboard.

Also you don't need to have the ONT near your other networking stuff. You can run CAT6 cables between the ONT and your RGW. If you do this run at least 2, preferably 4. Also the Chorus ONTs produce alot of light from their LEDs. The light also shines out of the vents so you can't just put some black tape over them. You wouldn't want an ONT in your bedroom because of this. And might also be annoying near the TV if you watch TV / movies at night with the lights off.

That's OK it can produce as much light as it want's in the office cupboard.  Might even be handy, as there is no light in there at the moment.

How would I run 2 or 4 Cat6 cables from the NT to the RGW? 

The RGWs I have seen only have 1 port for connecting to the ONT, 4 ports for LAN.

My parents' one is in the hot water cupboard. It's about 2.5 months old at this point and hasn't died yet, so an office cupboard should be fine :)

Mine is in the garage and is lukewarm to the touch - my router gets warmer than the ONT.

When I was referring to running 2 or 4 Network cables. I was meaning in the situation of the ONT and the RGW being in completely different areas of the house. Installs have been done with the ONT being in the garage. And the RGW being in a cupboard in the centre of the house with all the other networking gear. Yes you will of course only be using 1 network cable to connect the ONT to the RGW. But in remote ONT situations the installers don't like installing the ONT if there is only 1 network cable available to link it back to the RGW. As it means that the other ports on the ONT can't be used in the future.

Ok thanks for the clarification, I'm easily confused.  It's easier to put the ONT and RGW in the same place.
