those green boxes.

A box in my locality (Nuneaton) has been broken into.

Who would I contact to get it fixed as the little B******s around here seem to enjoy switching the mains switch off, cutting off my BB and CATV

Re: those green boxes.

The police for starters.......and then the firing squad! Kids these days have no fear!

Re: those green boxes.

They never electrocute themselves though. Same with lamp posts. If me or you tried it we'd be in A&E :rolleyes:

0800 052 2000 is your best bet

Re: those green boxes.

We don't have a problem so much with Cabs being broken open where we live on the wirral but down here where I am at the moment in bromley theres being broken into left right and centre. Loads of the cabs have big dents where you can see they have obviosuly been trying to get a crow bar into.

LWH1010 has been crowbarred open again.

LWH1010 --> where is that cab?

Re: those green boxes.

I've been keeping an eye out for these green boxes, in a sad anorak sort of way. There seems to be three types - the tall ones, with lots of doors, that seem sturdy but mysteriously are never vandalised (well not around here); the old, what looks like, iron/steel type with a big chunky lock on the door - these don't seem to be vandalised; and the modern small ones that are forever been broken into. Most of them around here have been given a good kicking so the door(s) is/are all bent in.

So blame progress methinks :)

Re: those green boxes.

People really are sad if they go round smashin these in... what's the point?

What kind of gear do they have in the ones with lots of doors?

They have some of these round our area.

Lots of doors the 5ft tall ones with three doors? They will be around all areas. It's the NTL equivilant of a telephone exchange (so if you don't have Caller ID in your area, that is the box they have to install the hardware in (as you can see there are lots more of these than BT exchanges), also amplifiers to get the signal for TV distributed in the local area, batteries to power the phone exchange in the event of a power cut (as telco is an emergency service or something). Cable modem equipment (is this where the UBRs are?). It's the termination of the NTL backbone into the local cables.

Others with full knowledge of the NTL network will be better placed to elaborate on this though.

The two smaller cabs are very similar for content, one just holds more than the other, nothing powered in there, just lots of terminations.

The big cabs are mux cabs aka nodal cabs.They are the termination point for the fibre. The muxs (multiplexers) turn the light into electric (as well as compressing all the signals etc.) from here on in it is twisted copper pairs to the home, via a DP/ DA cabs. It's not an exchange but it is fed from the exchange/headend/hub/switch. UBRs are kept at the headend etc not within the nodal cabs. It does have batteries in case of a power cut. I'm not sure of the life of them but its around a few days.

The fibre that terminates on the nodal cab is local ring fibre, the main ntl backbone fibre terminates at the headend/switch.

Generally speaking the nodal cab is telco only and they are usually accompanied by the main CATV cab, you will find two or sometimes three cabs sitting right next to each other. They usually feed an area of up to 500 homes.

Re: those green boxes.

There's a tall one near my house but I think it's higher than 5 feet and has doors at the front (2) and one door at each end.

I've also spotted a little green box on my house wall - which I hadn't noticed til now :rolleyes: Not entirely sure what it's for - it's probably only a few meters from the brown box that marks the entry point for the cable.

But this is where CLI hardware would need to be located as this is the first point NTL telco is put through copper?
