This is sort of DIY but internet related rather than plumbing or building

I have a friend locally who was having problems with the internet
connection (EE if it matters). She was sent a new router and spoke to
the support folks but she couldn't understand what they were asking her
to do.

Anyway in summary.

Web site prediction based on postcode 3-5 Mb - guaranteed minimum 2Mb.
Her WiFi connected PC and BT wholesale speed checker 0.25Mb.

My laptop connected to router with cable, router connected to master
socket with no extension, telephone line disconnected, logged into the
routers admin page - connected at 0.25Mb

On phone to EE tech support for about an hour, very friendly do a lot of
tests from their end accept that service is unusable and offer discount
for the unusable period.

But where he lost me was on the fix. He reckons that BT (open-reach
presumably) had put a hardware "band" on the physical cables at the
exchange and this would have to be removed. (2 to 4 days so we are still
waiting to see if this is indeed the fix).

I asked more about this "band". Its apparently to stop the cables
completely breaking if you try and push to much data down dodgy cables
(now his or my understanding have reached the end of the line). He says
it is frequently done but should never be as severe as on this line and
has almost certainly been applied in error.

I have looked on Google for Banding telecom data cables but no joy.

Does this make sense to Anyone???

I did have to bribe several BT engineers with tea and biscuits to get
such a clean line. The norm in my village is nearer 2Mbps.

You need to look at the sync rate and noise margins really.
Cable connection to router rules out local Wifi interference.

They may put some sort of filter on but I can't see that this level of
fault can be anything other than a bad joint somewhere in the signal
path - possibly one involving an aluminium to copper corroded joint.
That is what destroys broadband 500kbps in our neighbouring village.

I take it they have done a TDR line fault test and got "No fault found" ?

This makes no sense at all and sounds like bovine excrement. ADSL is
rate adaptive and the line will run with whatever signal to noise it can
support. If you keep on getting disconnects because of really bad noise
then the reconnect speed goes into a spiral of death down to 256k.

Until we can see the modem statistics it is all guesswork.

Even diurnal variations are visible if you care to monitor it.

I have looked on Google for Banding telecom data cables but no joy.

Does this make sense to Anyone???

I doubt if it made any sense to the tech support guy spouting it either.

Well they did remote resets of the router and remote logons to the

Quite what he did I don't know but he did make us hang up the land line
and he called us back on a mobile. I was on the mobile for the biggest

their end and several "I will just try and do so and so and you will be
on hold for about 5 mins whilst I do that". Then he would come back to
say no sorry that didn't make it any better.

to be fixed on site (2 to 4 days)

Never heard of such a band. I will ask my tame telco employee next time
I see him. I can believe that they found a bad joint by TDR testing and
will have to wait for BT Openreach to remake it. Usually they say
something like line fault (break) so many metres from the premises.

When they ask you to hang up the landline is about when they do the
test. You really don't want to be listening when they ping it with a big
pulse. Such tests sometimes heal a borderline intermittent failure.

Banding is a limit applied by the exchange if the connection keeps breaking.

Basically if your router is being regularly disconnected *for whatever reason* then
your data rate is restrcited so as to give you a better chance of getting anything at
all.

How they do this hardware or siftware is another matter.

Same as when you install a new router, you'll be advised that it will take time for the
router to "settle down". Basically the longer it stays connected the higher the band
you should be getting. There are sometimes arguments between customers
and ISP's as to how often this is being checked and their banding upgraded.

Thats not 'banding' thats the BRAS or IP profile

http://www.kitz.co.uk/adsl/IPprofile.htm

What in general happens is that a minimum noise margin will be applied
to the line such that it wont connect at higher spoeeds than would cause
the noise margin to be exceeded. Probabky 9dB on a long line.

THEN the BRAS is automatically calculated fromn the resultant synch speed.

The point of the BRAS is NOT to send data that has to be biffered in BTs
DSLAM at the excahange. Ther is, as I discovered , no upload limit
though - you can send as fast as you can synch.

ISP can get an IP profile reset in minutes...

But getting noise off a line means a call out to Openereach.

Broadband Faults Guide - Banding Guide

WBC 288k - 576k 288kbps to 576kbps
WBC 576k - 1M 576kbps to 1152kbps
WBC 1M - 2M 1152kbps to 2272kbps
WBC 1M - 3M 1472kbps to 3072kbps
WBC 2M - 4M 2272kbps to 4544kbps
WBC 3M - 6M 3328kbps to 6656kbps
WBC 4M - 9M 4864kbps to 9728kbps
WBC 7M - 14M 7168kbps to 14336kbps
WBC 160k - 24M Unbanded (up to 24576kbps)

Above are the levels of banding that can be applied to
your line by DLM (Dynamic Line Management). Banding is
applied when your connection drops on a regular basis.
The banding slows your connection by restricting your
connection rate. For example, if your connection drops
10 times within 24 hours, you may notice that your
connection is banded to WBC 4M-9M this means your connection
will only be allowed to synchronise at a maximum of 9728Kbps.
Your speeds are lowered to try and help your line stabilise.
Normally, your line should be WBC 160K-24M which essentially
means, your connection can synchronise anywhere between 160Kbps
up to 24576Kbps - this is a profile with no banding
on it. In a lot of cases if you have a fault where your
connection has dropped out, your profile will be restricted
to WBC 160K-288K which means you'll only see speeds of around
250Kbps.

Point 2. It cannot be the issue here.

Point 1.

No one else calls it banding.

The OP asked about bands.

Plusnet produce a page explaining what banding is. Supporting
what I'd suggested earlier but in more detail

The Plusnet page I quoted lists ten separate bands.

As a matter of interest what would you call them, instead of "bands" ?

Its BRAS or IP profile and always has been,

Except that the Op didn't ask about BRAS or IP profile did he ?

He asked about bands

What do you always have to complicate things ?

The fact that the people who he's talking to on the phone don't
seem to have a clue is not entirely unexpected. But that's
another matter entirely.

But whatever you choose to call it the usual advice is to never switch off your router
unless absolutely necessary for precisely this reason that it can trigger DLM
at the exchange. Although whether once a day would be enough is another
matter.

I asked more about this "band". Its apparently to stop the cables
completely breaking if you try and push to much data down dodgy cables
(now his or my understanding have reached the end of the line). He says it
is frequently done but should never be as severe as on this line and has
almost certainly been applied in error.

I have looked on Google for Banding telecom data cables but no joy.

Does this make sense to Anyone???

Besides, copper all the way over twisted pair is as bad as shoving it up the
mains, lossy and interference generating, no wonder they need firrite rings
everywhere. Brian

Not really unless the terminology is wrong. I wonder if its
interconnection with other cables either capacitive or something else.

This is sort of DIY but internet related rather than plumbing or building

I have a friend locally who was having problems with the internet
connection (EE if it matters). She was sent a new router and spoke to
the support folks but she couldn't understand what they were asking her
to do.

Anyway in summary.

Web site prediction based on postcode 3-5 Mb - guaranteed minimum 2Mb.
Her WiFi connected PC and BT wholesale speed checker 0.25Mb.

My laptop connected to router with cable, router connected to master
socket with no extension, telephone line disconnected, logged into the
routers admin page - connected at 0.25Mb

On phone to EE tech support for about an hour, very friendly do a lot of
tests from their end accept that service is unusable and offer discount
for the unusable period.

But where he lost me was on the fix. He reckons that BT (open-reach
presumably) had put a hardware "band" on the physical cables at the
exchange and this would have to be removed. (2 to 4 days so we are still
waiting to see if this is indeed the fix).

I asked more about this "band". Its apparently to stop the cables
completely breaking if you try and push to much data down dodgy cables
(now his or my understanding have reached the end of the line). He says

On the face of it this sounds like ********. "Completely breaking" -
what does *that* mean?

Yes that was my impression too but I thought I would give him the
benefit of the doubt. He seemed to be talking about the wires fusing,
now I can see this happening if you try and push to many amps down wires
but too many bits??????


Unless it's those ferrite jobs you see on some cables (I can see about
seven of those from where I'm sitting, on USB cables) but quite what
they do I'm not sure.

Chris B expressed precisely :

It is complete piffle. It reads as if their is some fault on the line
or EE are doing some very serious traffic shaping.

Never try to check upload and download speeds via a wifi connection. It
needs to be done via a wired connection to the router.

Sounds te same to me.

Find out what S/N ration he is wirking at

Stop RF propagating down the 'skin' of the cables

If the postcode lookup sez you should be getting X you should be.

In general failure to get speed is down to seriously bad cables, or a
LOT of interference on a long line - often from other users.

BT openreach can (if pushed, and treated to good tea and cake, or donuts
and coffee), select a 'quiet' pair and remake every joint to get the
noise down.

€œit should be clear by now to everyone that activist environmentalism
(or environmental activism) is becoming a general ideology about humans,
about their freedom, about the relationship between the individual and
the state, and about the manipulation of people under the guise of a
'noble' idea. It is not an honest pursuit of 'sustainable development,'
a matter of elementary environmental protection, or a search for
rational mechanisms designed to achieve a healthy environment. Yet
things do occur that make you shake your head and remind yourself that
you live neither in Joseph Stalins Communist era, nor in the Orwellian
utopia of 1984.€�

Ferrites on cables are supposed by adding to the inductance stop radiation
from cables getting out and into domestic equipment etc. Often used by radio
hams to stop their transmissions being picked up on speaker or line
connectors as well.

I do not believe one can break a connection physically by shoving data down
it, but group delays and reflections in standard copper cables can limit the
frequencies you can put down them of course, which could be seen as a break
in connection.

The truth of the matter is that we Scots have always been more divided
amongst
ourselves than pitted against the English. Scottish history before the
Union of
Parliaments is a gloomy, violent tale of murders, feuds, and tribal
revenge.
Only after the Act of Union did Highlanders and Lowlanders, Picts and
Celts,
begin to recognise one another as fellow citizens.
