FTTP replacing UG fed feed internal

[coleyjf]

Hi,

My existing cable pairs are fed via a duct ( duct100?) to a point under the wooden floor inside the house (in the hall) from a small footway box outside the house. (1980's house with suspended wooden floor about 400mm from the concrete raft)   can Openreach use the existing duct or do they have to dig across the garden and bury the new feed  and drill through the wall?  
Also  my current NTA is in a 1st floor office internal cable from the point of entry to said office), if they can't use the duct could they possibly put the new termination  outside that 1st floor room? 

Thanks for any info

Jim

You will need an excavation from the jointbox that houses the CBT to your house wall ,  the closest existing jointbox may not be the one containing the CBT , but as this part of the excavation would be in the public footpath it’s not really your concern , just the route from the path to your house wall ….

I’ve no ideal what you call a NTA is , but if getting FTTP all the existing copper distribution is made redundant, the master socket and any extension sockets etc will not be part of the FTTP installation …although you could reconnect sockets yourself to the SH2 router phone port if you take Digital Voice as part of your broadband package and want to continue to use extension sockets for telephony 

The internal device used with Openreach FTTP  is an ONT ( optical network termination ) a mains powered device, that can be placed within reason wherever you want it …..a first floor room opposite a telegraph pole when it’s  overhead service is likely to be less work and so acceptable to the installation people, if an underground service , they may be less inclined to consider it if it’s a considerable undertaking, but ultimately the installer will in negotiations with you decide, if the request is reasonable, then there is no reason to suspect they would not install the ONT where you want it , but if it would  take hours to accomplish this , they won’t .

Thanks for that, sorry meant NTE not NTA, it's been called so many different things in my ( long long) time both in BT ( And GPO telephones) and since retiring, I forget which one is current!! ( and which one is real!) 

Yes it's a shame they don't feed down the existing mini duct into the under floor area, save a load of digging, but I guess they'd have to cut and draw using the existing multicore (3  pair in my case)  ug cable which would leave no service between the times of fibre provision and service connection, over a week later

The 1st floor point us actually easier to get too than the front wall as there's a spiky hedge along the front wall 🙂 so we'll see what transpires.

I have heard of circumstances where the duct 100 is tried by the civils team before breaking ground , but that’s invariably where there is no service over the copper pair , so should it fail , no existing service is disconnected, and when the duct comes up on the external wall , not through the foundation and inside the property…the chances are the fibre cable can’t be pulled thorough using the copper cable as a draw rope most times it’s not even mentioned in the survey notes , so the process assumes a new duct is required.

Thanks, yes that makes sense.

Getting through Duct 100 is very hit and miss.

Really depends how many bends it has and how long it is.

I always found pushing ROC Fibre Cable through Duct 100 worked better than RFOD because it was more rigged.
