Title: I'm very confused
Post by: sof006 on October 29, 2020, 11:12:09 PM
 ???

So... My cabinet is cabinet 53 (according to codelookup) and also BT's own checker. So that I know for sure. However, according to codelookup I am 1,962m away from my cabinet (yes?) but... I am fairly 99% sure that my cabinet (labelled 53) is quite literally a 10 second walk from my house (depending if I walk fast or not  :P ).

Samknows also believes my exchange (cabinet) whatever its called, believes its also the same distance and gives me a postcode for its location NE288RA, which fun fact is where a grandparent of mine used to live. However I do not see any cabinets around that area on Google Maps (although images might be very out of date). BUT... I do find this?

https://ibb.co/ykL5rMf

Am I somehow (highly doubting this) connected to that building? Laughing at asking this question as I am under the impression that a line is ALWAYS connected to a exchange/cabinet/PCP before going anywhere else. If so, where the hell is my cabinet? I can't find it (other than the location I believe it to be).

Codelook lists an estimated distance to the exchange, not to the cabinet.
The cabinet is a green box nearby.
The exchange is a physical building where your copper line terminates.

I see, so does that mean because I am so close to my cabinet that explains why I get 71Mb or is it a little more complicated than that?

Yes, simple as that. The further away the slower the sync speed.
A number of things (quality of cable, external noise, number of local lines taking a service) can affect the connection speed but distance to the cabinet is the main thing.

The above line tells me that the central point of the NE28 8TT postcode, which corresponds to a public highway named Ryedale (Wallsend district, Tyne and Wear), is approximately 1,962 metres from the serving telephony exchange. It also tells me that for FTTC (VDSL2 based) services, cabinet "P53" serves 100% of the NE28 8TT postcode area.

It does not tell me the location of cabinet "P53", the Primary Cross-connection Point (PCP) numbered 53 and its associated "fibre cabinet".

From the above line I see that the "fibre cabinet", associated with PCP 53, is equipped with ECI electronics.  :yuck:  (An ECI Hi-FOCuS Mini-Shelf M41 MSAN configured as a DSLAM.)

And whilst I was researching and typing the above, I see that j0hn has already explained the situation.

Yes unfortunately I am well aware I am on an ECI cabinet... Its not fantastic however i've not had too many issues. I'd say i'm reasonably lucky considering my speed is in the 70Mb area. Unlike my friend who only gets 20Mb on the other side of Newcastle  :'(

EDIT: I have just noticed "expanded 14th March 2020" does that mean they've attached a pod?

Yes, simple as that. The further away the slower the sync speed.

Interesting, I always thought it was the exchange that had the impact. Learn something new everyday. Could the image i've post be my exchange? I'm casting doubt before any responses come lol

The two cabinets at either end of the exchange building in David Street are worth examining but, unfortunately, the resolution of images from Google's Street View car are not that good.  :(

I could make an excuse to take a trip to Wallsend Forum which i'd happen to walk past David Street on the way and have a look out of curiosity.

It could be that either another "fibre" cabinet has been installed or a side-pod has been attached to the PCP. As you know its location, how about going for a nice short walk and taking a picture of what is currently in situ?

What can I say other than yes, that is the Wallsend Telephone Exchange!

I'll take a look tomorrow when I take the dog for a walk ;) and thats crazy, I did not even realise for such a long time. It only just crossed my mind that it could be.

That is the case for ADSL, as that's where the signal originates from, for VDSL the signal starts at thr cabinet in the street, travels back to the PCP and then to the property.

That usually means a whole new 2nd fibre cabinet was built.
If it was it would be a Huawei.

This happened on my cabinet and i made a deliberate and successful attempt to have my line moved to the Huawei cabinet.

The pods show as VDSL Sidepod on codelook. They are also Huawei.
This is the exact same as having a 2nd cabinet build, just much quicker to deploy in a pod.

Would this cabinet be located next to my current one? Also how did you manage to get yourself moved over to a Huawei cabinet?

To add to the wealth of info already provided .... if you are indeed fed via PCP53 ... then it is located outside No.1 Wiltshire Drive.

The original DSLAM was an ECI - 256 port affair, but there has been a VDSL Huwaei side-pod - 64-port upgrade, done.

It sounds correct, the location is roughly around that area. I'm waiting for a parcel, once it arrives I'll go take a look

PCP53 is definitely in that location, no two-ways about it  ;) .... it's whether your own house location is around there, as to whether you're fed from it or not ??  :)

Surely I have to be, there are no other PCP's (that i've seen) in my area. I do live in that area.

Off topic but why does Yodel take so long to deliver a parcel? I find other couriers way faster (even Royal mail  :lol: )

Also how did you manage to get yourself moved over to a Huawei cabinet?

Either order a 2nd line which should come from the Huawei, then cancel the 1st line.

Alternatively you need to downgrade to ADSL, then upgrade to VDSL to get your current pair moved.

When you cancel your VDSL, OpenReach leave the line jumpered to the ECI cabinet so that they can remotely reactivate you if you order VDSL again (back on the ECI).
Ordering ADSL ensures the line is physically disconnected from the ECI cabinet.

The 2nd line route is the easiest, but isn't a 100% guarantee to be connected to the Huawei cabinet.

Since when do Yodel deliver, is that something new?

If there are 256 ports in the ECI Cabinet and only 64 in the Huawei pod, that's a 1 in 5 chance of being connected to the Huawei pod if you have a new line installed or do what @j0hn advised.

Here is the image of my ECI Cabinet and PCP.

It looks like the pod is attached to the PCP?

To my surprise it looks like they're coming today! 17 stops away  ;D

Those odds are just a little off. That's assuming there are 256 free ports in the ECI and 64 free ports in the Huawei.
Neither is true.

The Huawei pod has been installed because the ECI is full or near to full.

If both cabinets have free ports the OpenReach allocation system will favour the Huawei.

The chances are any new line will be on the Huawei.

There are a few examples in this forum of users swapping between Vendors.
I've yet to see a failed attempt at a swap.

A 2nd cabinet or a VDSL Sidepod is only installed if capacity requires it, meaning the chances are it will be on the Huawei DSLAM.

I detailed the process well and was specifically about what won't result in a cabinet change.

I also did caveat my post with

but isn't a 100% guarantee to be connected to the Huawei cabinet.

The 1 in 5 chance suggestion is actually quite absurd and is ignorant to the capacities and processes involved.

It helps if you know the ECI was on a waiting around the time the Sidepod was added.

That's always the case. It keeps the tie pair distance down.

The ECI's can't be expanded.

Huawei cabinets can have small extensions added to them but the pods are always on the PCP.

I see, interesting. I wonder if that was the maintenance that Zen had listed for my line on their status page a few months back?
Title: Re: I'm very confused
Post by: j0hn on October 30, 2020, 04:46:14 PM
Very unlikely.
It doesn't involve any downtime on the existing DSLAM or any lines on the PCP.

I would doubt it . . . unless Zen were being ultra-careful and wanted to cover their back, in case of a contractor's blunder.

Looking at the composite image, below left, we see the original cast-iron PCP still in-situ, back in July 2012. It would have been given a new pressed steel shell, prior to the installation of the ECI DSLAM in October 2012. Fast-forward eight years, below right, and there we see all of the currently deployed plant.
