Have you seen this page? It has most of the BT cabinets listed along with an image.

Re: Cabinet information query

In reply to a post by Vorlon:
I'll have to double check, but the cabinet close to me with the correct number stands alone without vents to my knowledge. Even a recent Google Streetmap confirms that, but I'll have to double check properly to be sure. I wondered if any of the cabinets go through retrofitting.


They often get "re-shelled" (literally the whole of the outside of the cabinet, but not alterations to anything existing inside it already) when they get a fibre twin. This is usually to accommodate the extra "verticals" needed for the links to the fibre twin, which are simply added beside the existing verticals; but sometimes because the existing "shell" is in bad condition.

I don't think I've ever heard of an all-in-one cabinet directly (i.e. at the same location) replacing an existing PCP, either reading these forums or in real life.

If you go to Page 5 of this document, there appears to be a photo of an AIO Cabinet, given its location with photos and descriptions of other solutions-

https://www.southdowns.gov.uk/wp-content/uploads/201...

---

The only obvious internal differences I have noted, without doing a rigorous comparison, is that the Filter/Links plugged in to the Back-Plane in the right-hand side, are coloured Orange, rather than White seen in conventional FTTCs.

The other difference is that in the local FTTC, all of the sockets in each of the loaded Back-Plane groups are occupied, except for the 25th (Brown sockets/fifth row, right-hand end) compared to the obvious gaps in the photo.

Externally, it looks similar to the Huawei 288 near my front-door, with some uncertainty as to its top, whether peaked like that Huawei or flat.

The two upper, narrow, vents in the left-hand door appear to be different wrt to the Huawei, the latter middle one being distinctly larger.

The vents in the R-H door appear to be similar to the local Huawei.

Agreed!

It does looks very similar to an FTTC; but as the photo is specifically in the part of the document covering other less usual Broadband devices, particularly pole-mounted; and is apparently directly related to the adjacent text line-

"Exchange only lines and secondary connection points � Copper rearrangement, All-in-One
cabinets" ...

Of course, it could be that BT has used an FTTC photo on a generic basis.

Perhaps someone has a photo of a known AIO cabinet; or can provide a link to one; or even a good description of one.

Given the apparent similarity to an FTTC, could these be used directly?

----------

The only other attempt at an illustration of an AIO that I have found, is more of a concept drawing - and not very good at that, the labelling being for three items that would also appear in a normal FTTC, eg "Fibre Spool" - and the one possible difference being a rectangular dashed-outline attached and apparently hinged to the inside of the R-H door, labelled-
"
------------------
| Frame for !
|holding MDF|
! |
...
! |
! |
------------------
"
Within the lower part of that label enclosure, there is a sketch of a U-section bar, its open side facing horizontally in to the back-plane area, with probably a hinge at the end of that bar in line almost with the R-H door main hinges; and a short U-shaped bracket, possibly for giving a closing fixing or clip to the inner side of the R-H door.

--------------------

Again I hope someone will produce or link to a photo, good sketc etc, of a known AIO Cabinet.

Nor me. Onesies look like this: image

The relative size of the door-holes makes it look like a standard Huawei 288 to me.

However, the perspective of the open door on the RHS looks wrong - it looks like the door is far too wide to fit in the hole!

Thanks, WWWombat.

Interesting to compare the R-H sides of all of them.

I wonder if anyone can now describe the various contents, which I suspect are small Distribution Frames, to terminate effectively the directly-connected E-side and D-side wiring.

---------

The third, Twitter one, looks as though it can handle only 96 circuits, although apparently wider than my local Huawei 288.

Although apparently covered, the Aysgarth one also seems to be 96 circuits.

Difficult to tell directly with the Warsop one, probably 96 as well; but the photo does show the wider cabinet width.

You see from the larger view that there are 64 filters plugged in, with space for another 64 .

Thanks again!

I had not noted the different grouping, of 36 sockets, with the last four Filter/Links omitted in that AIO.

Compared with the 25 sockets with only the 25th Filter/Link omitted in the Huawei FTTC.

I live and learn!

----------

Have you or anyone else any idea why those omissions take place?

Seems wasteful, unless it is to have some in reserve to cover failures - but that would appear to require wiring changes in the PCP, if it is a conventional FTTC-PCP installation.
