Came across this diminutive cabinet while out and about in the Lake District, it is quite dominated by its huge neighbour. The cabinets are in a fairly small hamlet, so I wonder how many subscribers it can serve? We were staying in a nearby hotel and the proprietor is now enjoying "Superfast" broadband. He has also installed a new mesh wifi system which no doubt serves well the demands of the modern day traveller.

Looking at that primary cross-connection cabinet, I can deduce that it dates from 1981 at the earliest (the T logo of the recently created then privatised British Telecommunications plc) and is the "tiny brother" of the fibre-glass family. As for the number of circuits that can be squeezed into it, I would say a couple of hundred. Perhaps Black Sheep will be able to disclose the "official" size?
I would say that its Huawei equipped "fibre twin" is probably capable of providing a G.993.2 based service for every one of the circuits that transit through P1 . . .

Thanks burakkucat. :)

It's hard to say how many circuits run through Cab1 without looking at our CSS Database, just as it's almost an impossibility to give an accurate capacity figure, without actually looking inside the Cab.
The reason being that the older 'threaded' system of connecting, that sees individual 'verticals' (verts) of 100pr cables would maybe house a total of four in a Cab of that size ..... whereby if the more modern Krone, Quante or the very latest push connection blocks were used, you could easily triple the Cab's capacity.
The smallest Exchange in the UK (as was back when I worked up in the Lake District), was Buttermere ... and it only had 20-odd 'subscribers' as they were then referred to working off it. That's 20 in total, not 20 in a Cab !!! Memory also recalls that a good few of those circuits were also a PABX system at the only hotel there was down the road. :)

'subscribers' as they were then referred to working off it.
Has the term 'subscriber' gone out of fashion, then?
-
Oh yes, a long time ago ............. they were moved to 'Customers', then to todays terminology of 'End Users'. :)

I hope the individual(s) who made that decision budgetted to update all the technical documents and international/european protocol standards? ::)

Ok, thanks to all, I was just curious as I'd never seen such a beast and found the juxtaposition of the two cabinets amusing. ;)
