Does ADSL always come from the exchange. Exchange only line.

 

 

 

I was thinking about an observation of @imjolly  . Well spotted.


e820670DslCheck.jpg


As you can see not a lot going on here ADSL that's basically it, but from cabinet 1 not EOL?

Our exchange has two cabinets.

Cab2 7/8km I'm guessing from my house.

Cab1 is 4997 meters from my house. Cab1, VDSL enabled, is 3 meters from the exchange.


So it would appears I am connected to a VDSL DSLAM with a moonlight job serving ADSL.


If this is possible may explain why shift from ADSL(0)Max to ADSL2(plus) took 31 minutes at 8 o'clock at night.

The only scurrying in the exchange at that time of night will be the rats.

Man pressing buttons in Newcastle-Upon-Tyne.

As you can see shows date 12/04 before midnight

Completion Planned Date  

A planned date for your order to be completed has been assigned. 

Contractual Delivery Date : 12/04/2019 23:59:59 | Completion Planned Date : 12/04/2019 | Reason Code : | Reason Text : | Delay Code : | Amend/Cancel cut-off date : 11/04/2019 |




May explain why upload cap took 8 minutes from order to shift. Man pressing buttons in Northern Ireland.


The other bizarre thing is, and the accountants are no doubt responsible for this one, is.

The exchange which looks like and is the same size as a single public toilet is in the middle of no where.

A leftover from the topology required to do phones 100 years ago. Explains a lot about Openreach network.

But 1 1/2 km from my house is the village where most people served by cab1 live.

In the village there is a hut, looks bigger than the exchange from the outside, crammed full of true fiber optic kit.


This is where my and every spare exchange line emerges from its cosy pressurised, to keep the rain out, subterranean cable.


My cable and all the spares have the same high resistance 6 ohm continuity fault.

7 ohms and they would be required to fix them so they don't.


So with another 1/2 meg of my download lost it is shunted 10meters across the road to a rusty old box.

The BB+T engineers are not worthy enough to be allowed, hence no DSLAM accountants again, in the hut.

It then continues overhead to my DP. From there is another story all in its self.

 

Does this explain why @jamben1864  has to wait for two weeks.

Because someone at Openreach forgot to order the coal.


And @.... funky old DSLAM in the exchange has run out of steam. An requires pressing of buttons in person and not remotely?


SIN 498 7.5/18 looks like a real 133 page ripping yarn.

The answer now I've just bothered , I'm lazy, to look is on page 2. I'll save the wrest till bedtime.


Optional Extra.

ADSL DSLAMs are sited in exchanges, VDSL DSLAMs are sited in cabinets. ADSL is never served from a cabinet, there is no technology present to do so. ADSL circuits will be routed through the copper PCP not the associated DSLAM cabinet.

Re: Does ADSL always come from the exchange. Exchange only line.

So after a few phone calls I can confirm.

Green cabinets can dispense any colour of broadband. AdslMax-FTTP

And I guess if your line says Exchange only you are stuck with an old funky steam powered DSLAM in the exchange.

That reminds me I must order some coal.

No, read my previous post. FTTP doesn't come from a cabinet at all.

Re: Does ADSL always come from the exchange. Exchange only line.

 

Thank you for replying.

 

Ok I was writing last post as you posted. Read and taken on board.

Is this stated in a SIN anywhere?

So that's FTTP off the list.

If my line passes through cab1 , it's only a pair of connectors in the cabinet.

Why does dslchecker say served by cabinet 1?

It should say EO but it doesn't? An error?

5 to go.

Because that is where your copper pair is connected. Read what I wrote. EO lines are nothing to do with broadband per se, it means that a copper pair doesn't go via a cabinet.

So I must have a different DSLAM to @jamben1864 .

Is that why @jamben1864   has to wait for two weeks?

I'm on a Huewai DSLAM or was on ADSL(0)Max.

Can't see HUB 6A giving me that info. Backdoor And Broadcom chipset would tell me like netgear DG834GT stock.

Thank you again. Sorry more questions.

Definition of EO now clear. Thank you for the clarification. Taken on board.

Is it a mod job to edit thread title for acuracy? or can I do it?

My line just happens to go through the cabinet 3meters from exchange.

So DSL checker is 'technically' correct but I have no access to Cab1?

Could I trouble you for definition of 'jumpers left in' ?

There on my line but none of my neighbors ADSL2(plus) lines.

The list I think now looks like this.

What about the bad apple left in the barrel? ADSL2+
