Hatherleigh Cab 1 capacity

Hi all

Cab 1 on Hatherleigh exchange (WWHATH) has been out of capacity since the end of 2015, I have tweeted CDAS on a few occasions but have had no reply

A friend of mine has just moved on to this cab and obviously can't place an order yet, does anyone know if the cabinet is full eg waiting for another cabinet or just waiting for more line cards etc.

Thanks

Well I aven't done any receint checks on that cabinet since the last time I did a full exchange check, sadly BTW blocks my IP after about 50 to 100 checks so I cannot do any more checks, but if I recall that was a rather full cabinet back then.

--------+---------+-------
Type    | Cabinet | Amount
--------+---------+-------
FTTC    |    1    |   590 
ADSLx   |    1    |     7 
NONE    |    1    |     4 
--------+---------+-------

The above information has probably changed since the May 8th 2015 when I was able to do the checks last.

Not really sure on the max amount of lines a fibre cabinet can support before it requires an additional cabinet installed.

I think the largest cabinets can support 288 VDSL connections.

I think its higher than that due to there are several FTTC cabinets on my exchange in London that handle 775 lines, I think it would be silly to only allow only the first 288 lines leaving about 480 lines without fibre, codelook says that it has passed 675 properties.

Maybe there was additional FTTC's installed for them, or added capacity, who knows.

Paul

I'm pretty confident that's the largest cab.

Average take up is only around 20% at the moment though, so even on 775 lines, that would only be around 160.

Properties passed just simply means that those 675 lines have the option of FTTC, not that there is capacity for that number of lines as such.

As you say, there is the option to add an additional fibre cabinet should the demand warrant it.

Well I know I am not going out and knocking on all those doors asking if they have fibre LOL, so I guess we will never know who has it and who doesn't LOL.

The back plane of sockets on the right-hand side, may be for 288 eventual connections; but my local cabinet, a Huawei 288 FTTC, had only 48 of the Filter-Links fitted whn RFSd at the end of March 2014.

In June 2015, it had another 48 added as I talked with the person doing it.

About two months back, it with the associated PCP had 63 actual Upgrades, might be about 70 now - not many requests for upgrades from the approaching 300 D-side lines from the PCP.

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

When the FTTC was being installed, the BT lad about to do the FTTC end of the link connections mentioned "100 pair links".

When the FTTC was opened for other reasons recently, I noted that there were only two link cables coming up from the almost 4 inch duct, with a second empty duct.

The two link cables about 1 inch diameter, apparently have 100 pairs of wires each; and two pairs of wires are needed to complete the upgrade, thus the present complement of 96 Filter-Links more or less matches the available link wiring.

One of the two pairs is to extend the E-side pair to the FTTC; and the other pair extends the D-side pair.


So it appears that when the present 98 F-L limit is approached, not only will more Filter-Links be required; but additional 100 pair Link Cables.

It took about 5 minutes to fit the second batch of 48 Filter-Links.

I suspect that it will probably be about 2 days, to draw in the Link Cables underground, with an almost 180 degree reversal in the Underground chamber about 5 metres away from the FTTC, towards the Exchange the FTTC.

Followed by 40 metres including past the FTTC, to another UG chamber about 5 metres from the PCP, where there must be a 90 degree turn to access the PCP about two metres away.

And at both cabinets there is the 90 degree vertical bends to actually enter the cabinets.

Obviously I don't know the spcifics of your situation; but it is probably very similar.

The fibre cab on PCP1 is a ECI cabinet the normal size not the 288.
Last week I spotted workmen and a lorry with a green cabinet on the back, I thought great another fibre cab is going in.

But nope for some reason the existing PCP has been completely removed and a brandnew one installed, so god knows what is going on.

The old one might of been too small to cater for possible new lines, so a newer larger cabinet was installed.

Paul

This is the one that was removed not sure why as it was the newer style, prob a couple of years old.

Hmm, that's not an old looking PCP Cabinet that I was expecting to see.
That looks like a rather modern cabinet, maybe rust from the river behind it, or maybe some defects in the cabinets outer shell.

I am assuming it was just the outer shell that was replaced, it would take a very long time to replace the entire internal wiring, normally when everything is being moved over to a completely new cabinet, they have to install it as close to the other one, or an agreed suitable location agreed by their planning team.

So if it was just the outer shell that was replaced then there was a structure issue with the old cabinet, maybe somebody welded the doors shut LOL

In our case a couple of years back, our new PCP cabinet was installed about a few feet from our old cabinet, however our old one has been left in place.
I am not fully sure if we have been moved over to the new cabinet due to the last time I was there I didn't see any padlock on the PCP cabinet, but that was a long time ago.

Paul

Yes mate it wall all done in a day so I presume just the shell was changed over.

Ok, then I would think something was wrong with the previous shell, maybe a vehicle caught it, or like I already said it was vandalised etc.

Paul

It's common for PCPs of all ages to be re-shelled when they're FTTC-enabled; usually because of the two extra verticals which the PCP needs. It isn't set in stone though, sometimes villages with tiny PCPs get twinned with a fibre cabinet which is smaller.

The largest Huawei cabinets handle 288 connections, 6 x 48 port cards. We've 2 of them serving our PCP here, one full the other part way through card 5.

Drove past today to see 3 OR vans, and the PCP and fibre cabinets wide open, looks like they were feeding more pairs to the fibre cab as could see bundles of cable lying on the floor outside.

God know's what is happening, still showing at wait list. However about a week or so ago this cabinet was put up beside the fibre cabinet any idea's what it is for?

dunno. not an openreach/bt cabinet but appears to connect to the network so maybe for a mobile phone mast or other utilities monitoring
I seem to recall that cab 1 required additional tie cables and duct.

Spotted a load of work going on near Cab 1 and a new Huawei 288 has been erected today so I guess the existing one was full to capacity.

Just quick question does this require a new fibre line from the exchange or can they split the fibre from the existing fibre cab?

There's usually a bunch of fibre cables ran to each cabinet so I suspect they'll just use one of those. I could be wrong though, they may run another from a nearby node/manifold.

New fibre to the aggregation node

While you're here, could you give me any more information on Whitley Bay cabinet 63 please? In the build phase but not seen any action thus far.

Might see something happen in the next month or so

Top man, cheers!
