link to pic above, inside the cover is a load of junction blocks type things. Two wires link to the pole, one wire goes to a white splitter thing maybe , and then two wires leave this thing and go to neighbouring properties

there's another smaller black box on the back wall with a similar rats nest in..

It is a BT distribution point. A set of terminals to connect the pairs on the multi-pair cable to the individual cables to subscriber's premises.

It belongs to BT and must not be interfered with in any way other than by OpenReach technicians.

If a person tampers with the box and accidently ( or intentionally ) disrupts telephone service to one or more of the subscribers then that person will be at risk of charges which could include compensation to those subscribers who lost service ( and possibly business ) as a result of the tampering.

It's a mini cabinet! Woo! Must check where it is on the FTTC rollout then i can get FTTH..

hrmm..

ok, so here's the other box of rats nest that is down stream of the large one pictured above

is this a mini distro point? I'm looking to demolish the wall this device is on.. Should i get Bt up ahead of time to remove this and put a couple of new wires in to new master sockets off the distro above? The building is to be converted to 4 residential units. Will large numbers of sockets on a distro box impact the broadband provision (is it sharing wires or is it using redundant cores in the existing ?

thanks!

No, there's (normally) no sharing.
The incoming cable will be 10, 20, whatever pairs - all electrically separate. All these boxes are is a set of terminals to link incoming and outgoing pairs.

Say it was a 10 pair incoming cable - that could feed 10 separate houses with one pair each. Or if some of the customers were businesses, there might be several pairs to one business. A dropwire to a single premises might be 2 or 3 pairs for a domestic - the spare pairs will be coiled up and left inside the box for future use, with just one pair connected to a service. Typically the inside of these boxes looks like a plate of thin spaghetti has been thrown in and the cover slapped on before it escaped !

This is how the phone system typically works. At the exchange there will be some very large cables (perhaps 10s of thousands of pairs in total) that radiate out to the green cabinets on the streets (or joint boxes inside the manholes). Here, smaller cables radiate out to smaller distribution points (like those you are enquiring about), and so on until a single service arrives at your house. At each distribution point, cable pairs will be connected together so that there is a pair of wires from your master socket all the way back to the exchange. As long as the cable isn't faulty, your service will be completely separate and unaffected by all others in the larger cables.

The large black ones are called BT 41,the grey one is a BT 66,there is a good chance that the top one is a distribution point (DP) and possible feeding multiple end users,it is classed as a E DP,contact openreach if you need it removing as third party damages could be very costly if you knock of any of the other end users when you start your building work.Chances are if you own the house openreach will do this for free because it will prevent any future access problems,they used to put DP's in peoples gardens when there houses were owned by the council but now the houses are in private hands the householders are not happy with Hairy arsed openreach engineers trampling through their gardens.
