I've noticed that our fibre ONT box is has a cable connecting to a regular old fashioned phone jack. The phone jack has another cable in which I presume is the old copper line.

Does anyone know why the ONT device is connected to the phone jack? Would it cause any problem to disconnect it? We don't use a landline and it's just more cables getting in the way.

Thanks.

Yep you can disconnect it.

The ONT can have a phone service running on it if the provider supports it. As you don't have a phone line activated you don't need to have it connected.

Thanks very much. Do you know if it's easy to take out of the ONT box itself? It seems to be wired into the ONT and I haven't tried opening the box itself.

If it's not connected with an easily removable plug you might be wise to post a photo.

Assuming it is just for a landline connection, it was probably Chorus ticking a box to allow a landline at some point. Based on my parents experience, the Chorus tech said it was all wired up so all the existing phone jacks in the house would still work. Problem was it was internally wired but they didn't connect the ONT to the existing phone network with the cable you mention.

I didn't realise how it had been done so was tasked with calling the ISP for help. Turns out simply running the appropriate cable from POTS1 on the ONT to the phone jack livens up the network. I then tested then asked my Dad if he figured out how the mechanical bells in one of the corded phones still rung powered by a tube of light 🤣

The base of the ONT that terminates the fibre (Not the ONT itself) will have an RJ45 in it, this will be what is connected to the house wiring. then if a land line service is ordered, You would connect this RJ45 to either the POTS port on the ONT, or the Phone port on the modem from the ISP to liven up the phone ports around the house.

Hmmmm

Hmm, I'm not sure how exciting a photo will be. It's just a white cable disappearing into the ONT box.

Has anyone opened up their ONT box? Or had an electrician do it?

you personally are not allow to do it nor is a electrician, the only people who can do it are chorus (or which ever LFC are in your area) its their equipment and their network.

if you post a photo people can tell you what you are looking at

RJ11 in the ONT/RGW. My Install definitely has an RJ45 in the termination box on the wall.

Here's the under side of the box. The phone connection is the white cable on the bottom left, and as you can see it doesn't have an easy to remove plug.

Hi, bit of a sloppy install I would say, normally the existing house wiring is terminated on the RJ45 to the right of the cable, and a short fly lead can patch from either the ATA port on the ONT if supplied via that or from your ISPs router is supplied from that. So that cable to the very left would normally not exist. I take it its just a copper lead with an RJ45 on it?

I can't tell what's on the end really as it's inside the box. It could be just a bare wire onto a terminal of some sort. The other end is wired into the normal telephone jack as pictured:

Hi, all a bit rubbish, if it were me and assuming your not using the phone wiring in the house, take to it with a pair of pliers up near the ont, and off with its head.

Just check inside that phone connector first, but snip

What would you be checking for? I think you might be right about the snip by the ONT box.

Hi, just checking its not opti5e, which would contain unterminated fibre, just need to check that if you snip it you cover the end to protect from possibly exposed fibre cores, bit of tape over the end would do, if its just copper then all good
