Not quite broadband, but hoping someone here can answer my question.

On this website... http://www.micklebring.com/crb/alternatives.htm it
states that Home Highway has a maximum reach of 2km from the exchange. But
I am wondering if this is correct information as I have home highway but I
am just over 6km from exchange which is why I cannot get adsl.

Well as you have it, the information is obviously incorrect

When Home Highway was initially released the limit was something 3.5 Km but
it was later extended....

Sunil

Not obviously incorrect. I was hoping that the BT line checker had the
wrong information and my line was in the maximum distance allowed.

I've posted this somewhere else but given I know how hard you have tried to
get ADSL!..

BT are looking internally at increasing the ADSL limit to 70dB.. maybe as
soon as sometime this summer.

Assuming it happens, from memory you should then be able to get ADSL..

Sunil

It's not correct - the limit is actually an attenuation limit but it usually
translates to a maximum distance of around 5km. See my tutorial at
www.mckerracher.org/highway.

Keep trying for adsl - they are extending the reach all the time with new
technologies such as RADSL.

I have tried my utmost Sunil, well you have seen my posts over the last year
or so. It kills me that I cannot get it. Sad thing is, I dont particularly
want it that bad, its the principal of not being able to get it makes it
worse. Kind of like a rebellion.
If they increase the loss to 70db then I am definitely in with a chance as I
am sure my last recorded db was 65db
I have read alot about the adsl 2 which looks promising but again its going
to take some time to develop into a product.
BT advise me to place an order every few months just incase changes do
happen, so today I have placed another order. But I know it will fail. I
just wait for that lucky chance to happen.

But even at 5km theoretically I should be out of range of isdn. BT say my
line length is 6.75km. So you can understand my confusion on this matter
:-(

As I said, there's no theoretical distance limit, there's an attenuation
limit and a signal-to-noise limit. You must have thick wires and quiet
neighbours (or else BT's distance measurement is wrong, which is also quite
possible).

I wonder if my line is within the 6km required for adsl its just not saying
on their database.

you seem to know a lot about your line, distance, db loss etc..

How do you find this information out? Surely bt wont tell you as they gain
nothing from it by giving you this information, do they?

I would like to know my line specs, as the phone number checker says out of
range too, but by how much, i dont know!

All from BTopenworld. When I failed the line tests for adsl I rung them up
and asked for answers as to why it failed. They were extremely helpful and
contacted BTwholesale for me and explained most of what I needed. They told
me the db loss and also the length of the line as stated on their systems.
I dont know if you can get this information from them if you have not been
able to place an initial order.
My advice to you is to phone BTopenworld sales and get them to place an
order over the phone. As soon as they say the distance is too long and can
not proceed with the order, ask them how long the line is. They may tell
you, it probably depends on the person taking the order. Obviously if they
are able to place the order you can always cancel afterwards if you dont
want to go with BT.
