Since VM decided to mess up my net connection i made the decision to switch over to ADSL, my flat has a BT line which will be made active next week.

However...the previous owners took out the master socket and left only the junction box (pictured below). BT are telling me that it'll cost £125 to send over an engineer to hook up a new one which i think it a total rip off and doesn't look all that difficult.

The junction box has 2 active cables which i believe are the A and B cables, whilst the others are inactive, i believe it's just a case of buying a new cable and inserting them into the punch down connections on the junction box, and then into the corresponding connectors within a new master socket.

Any advice would be most welcome.

 
The picture is not helpful. Basically you have to wire the active pair onto A and B on the master socket. Polarity is irrelevant, assuming you wont be using ancient equipement!

Use an "IDC tool" in order to insert them properly and avoid any damage.

ADSL is very sensitive, therefore start with the entry point (master socket) as a point of reference. Filter is IMPORTANT, buy a quality professional filter. Then add extentions/wiring as necessary and recheck attenuation(db)/sync speed to confirm. The "bell" wire is irrelevant (sometimes proven to slow you down), do not use it, just the active pair (A and B).

What you have the is standard junction box, find the active pair, and connect it to a new cable to the master socket. Colour codes for pairs depends on the cable but it looks like you got Orange & White and Green & Black.

A and B or pins 2 and 5 on any master socket, or better yet get a BT ADSL nte from ebay
 
White (A)
Orange (B)

if you go by standards, unless the pair was damaged and other wires were used. Just test them when the line is active.

Use an NTE5 as littlesave said just to get rid of old corroded components and make it look the BT way :p
 
Hope I'm not too late into this thread, if you contact BT and say that you want to speak to promotions, say you are coming back fom virgin and they do an offer fr £29.99 for a new installation. Beats £125 if that helps?
 
BT used to offer free installation if there was once a BT line installed, dont know if they do this anymore, I was over 5 years ago that i last worked for them
 
Thanks guys, i'll give BT a call to see if i can get the reduced rate as i'd have to spend at least £20 on the hardware to do it myself.

If i can't get it then i'll give it a go myself.

Insist on the £29.99. I had mine installed yesterday for £29.99. Even if you sort out the socket yourself you will still have to pay for an install if there is no ringtone so let them do it for £29.99.
 
IIRC, You're not supposed to touch this yourself, as technically BT owns everything upto and including your master socket backplate (Front plate is excluded).

Although, I don't think anyone really cares.

As for house insurance, why would a phone line effect it? It runs approximately 3v, no different to putting a couple of AA batteries in your remote :)
 
They've agreed to do it for the £30 so good news on that front, bad news is i just can't get them on the phone long enough to finalise the engineer callout, their phone system has dropped the call 3 times and i've spent over 2 hours on the phone to various people (mostly on hold), the only time i get through to the service guys and their system is down.

Not a good sign that they can't even get their own phone system in order whilst trying to sell me mine.

Got the offer written onto their system though so it should all be ok!
