Hi,

I though I update everyone. So we are on the second to last day of the street works request and team of civil engineers has turned up.

That sounds like good news. Trust me it isn't.

They basically don't know why they are there. They have been asked to dig a hole. Which they have done.

However, they're supposed to be putting in chamber... Hmm. Correct me if I'm wrong but isn't that lot power cable?

More when I know more... This is getting out of hand.

Regards,

Gareth

Looks like grey BT duct to me.

Panic over. They found the BT/CATV duct and have dug a chamber sized hole around it.

This could take some time.....

Telecoms duct is grey. CATV is green.

Yeah, they'll put a BT footway box there, depending on the size of it they might want to put a fibre splitter/whatever other type of node there.

I can't quite tell because of the size of the image, but it looks like they've hacked into one of the ducts, doesn't it?

Electrical ducting is red or black depending on voltage IIRC. Water blue, gas yellow.

Are you sure?

The CATV duct AND telecoms duct are one in the same AFAIK. The copper phone lines and CATV enter properties from the same ducts and chambers. Each house has a small wall mounted chamber.

Sorry I should have said this is BT owned CATV not Virgin etc. As featured in the 2010 FTTP trail - just sadly not on that estate.

The above shows the hole now dug for the chamber with the now partially exposed CATV duct.

But, thats my understanding. I'd still like to know what the grey tubes are?

CCTV is usually green ducting, isn't it?.

Ordinarily the answer would be what everyone has said - they are BT ducts. The 2010 FTTP trial complicates things slightly, with regards to exactly what is contained in the BT ducts (i.e. how much is copper and how much is 2010 fibre). However, I don't think it complicates your situation regarding the install of your current FTTC cab - BT are putting a footway box there for ease of access. They may want to put a fibre splitter/aggregation node or whatever in there, but they may also just want ease of access to their ducts for the copper cross-connection of the FTTC cab to your PCP.

The estate doesn't have any FTTP trail fibre. But, the design of the infrastructure is the same as areas which have and is non-standard. It has been done on some new estates but not on others. It is unlikely to be added to any new estates in the future as it was only necessary to support the CATV network.

Thanks for that. Yes I agree I think what people are saying is right. I saw the subcontractor cutting into the tubes to either replace the covering or provide access.

They have continued to work on the chamber over the weekend and it is now installed. I suspect OR will be along on Monday to do the necessary work as they can't leave the cables exposed for long.

The aggregation node is further down the road in a circa 2012 chamber and will also be supporting a number of FTTP PONS. Due to the CATV there are lots of chambers. FTTP is planned for 300/900 homes for installation in Aug/Sept this year.

The FTTC/FTTP installation for the estate has been pretty traumatic for OR we are on our 7th set of roadworks. The village next door had most of the payments dug up to get fibre into the area. The impressive thing is that the CATV doesn't come from the Exchange it comes into the estate from a different direction. BT could have run fibre via that route and potentially saved a lot of messing about.

Anyway, thanks to everyone for all the information. Very much appreciated.
