Excellent, thanks everyone. It sounds like I'm safe enough to get the cabinet set up now and start moving all my equipment into there. There's easy access in the roof space from the top of the cupboard to where the phone line comes into the house - there's even lighting up there installed by a previous owner, so if the FTP can be at the side of the house of the front bedroom it should work quite well.

One last question - is there any requirement for an FTP to be a certain distance from gas bottles?

I wouldn't think so. There is nothing 'live' in them.

yes there is -

Direct quote from Chorus install Doc

Various AS/NZS standards detail an exclusion zone for gas regulators for reticulated gas supply and for gas cylinders housed outdoors. No potential sources of ignition can be installed within this zone. A telecommunications ETP (fibre or copper) cannot be installed within the gas regulator exclusion zone.
In order to comply with AS/NZS Standards no new fibre or copper ETPs can be installed within the Gas Regulator Exclusion Zone.
 ASNZS 3000 - Electrical Installations (known as the Australian/New Zealand Wiring Rules) outlines the Exclusion Zone measurements for Gas Cylinders and Reticulated Gas Supply regulators.
 ASNZS 4645 – Gas Distribution Networks outlines the requirement for gas regulators to have sufficient safe clearances from various building features including sources of ignition.
 ASNZS 60079 – Explosive Gas Atmospheres defines sources of ignition.
Any network transitioning the exclusion zone is required to be housed in continuous duct without any joints or junctions.
For NGA installs where the fibre ETP would normally replace the copper ETP, and the existing copper ETP is situated within the exclusion zone, the copper ETP should be left alone. A new fibre ETP outside the exclusion zone will need to be installed. Where a copper backfeed is required, this should be completed at the nearest jackpoint internally, or at the ITP – whichever is most convenient.

Depending on the type of regular/bottle etc - will depend on the distance - but it is from 400 to 3500mm and this is speced in the chorus install docs for all situations (specifics from the standards in plan installer english :-) )

Ooops, My bad. Thanks for that.

My place is scheduled for UFB in September this year so I'm trying to get my 1920s bungalow ready and tidy up my network at the same time. I'm looking at putting in a 9RU 10" wide mini cabinet (http://www.pbtech.co.nz/index.php?z=p&p=CHSDNX1018&name=Dynamix-R10WM9D-9RU-Mini-Cabinet-for-10-Panels----) and relocating my switches, router etc from my home office into the cabinet to be placed in a cupboard towards the back of the house. My main question is do Chorus have requirements about where the ONT is to be placed, will Chorus force me to put the ONT near the front of the house? I've heard that because our power and telephone are currently aerial drops the fibre will be the same, the telephone currently comes in above the master bedroom and I'm not keen to have any equipment in there (the built in wardrobes are going to be ripped out at some point). Ideally I'd like to place it all in a large cupboard at the back of the house as it's where the manhole is and it'll be easy to drop cables down behind the walls, and most importantly it's out of the way.

I was also wondering where do they put the demark point when it's an aerial drop, is it up in the roof or could it go in the cupboard as well?

External fibre termination point (FTP) will be outside high on the building near the aerial drop, but the demarcation boundary will be the electronic fibre box inside (the ONT). This will be in or next to any cabinet you put up if you request it, otherwise without any instruction from you it will likely go in the dumbest possible place next to your TV flashing lights around the living room so that kids can break the fibre input.

Have a look at the flat home hub type cabinets, there are some from Dynamics, Signet, Hubbell etc that mount flat on the wall so you can easily put them somewhere out of the way. They will run a cable from the phone demarc to the new box to interconnect existing phones into the new network. It has to be reasonably accessible, and best to get one big enough to allow space for TV splitters, network switch and router, and to add more things in future.

Time to find a new industry!
