ISDN --> ADSL
Posted by Tim on March 21st, 2005


Hi

My local exchange (2.5 miles away) has just been upgraded to ADSL. I
currently have home highway ISDN and was hoping to upgrade to ADSL. I
placed an order for ADSL and after a survey on my line by BT wholesale,
they say my line will not support ADSL. I was under the impression that
if ISDN worked then ADSL would most likely work?

I have been told that there is absolutely nothing I can do about this
by BT internet (my ISP). I contacted BT wholesale directly but they
were no help. Other people in my locality have ADSL, can anyone suggest
any further action I might take?

Tim

Choose an ISP which knows how to deal with conversions and has good
connections with BT - for example AAISP would be my recommendation. You
may find that they get more information on why your line has failed and
you may be able to take action to get the line to pass.

AFAIK you have do get your ISDN service disconnected and then apply for
ADSL. If the BT line checker finds ISDN on a line it automatically says
you can't have ADSL.

============


You mean BT would simply say "you can't have ADSL on this line" because they
find ISDN on there at present, without volunteering the information that if
you take ISDN off it may well support ADSL? Don't they want the business or
something? A response of "this line will not suport ADSL" sounds as if it
will never support ADSL; a better response is "We can't test the line while
ISDN is enabled, but if we take it off we can do the line test and *then*
give you a definitive answer".

Hi there,

Most ISPs can order a managed conversion for your ISDN to ADSL as a one-
step process so you don't have to have the ISDN line removed first. It's
possible that when you applied they got the idea you were on a normal
land line as opposed to an ISDN line and rejected the order. At that
distance from the exchange it should be easily possible to have at the
very least 512kbps ADSL.

IMHO it is just possible, but perhaps unlikely, that the information given by BT is in fact true.
Perhaps your property has a POTS service that is not over a coper pair. This would support ISDN but
not ADSL.

Meanwhile choose another ISP for a managed conversion of ISDN to ADSL. Arrangements are made to
test your line for suitability for ADSL and if it fails your line is restored to ISDN use at no cost
to you.

There is an extra cost, payable to BT, if your line does pass for ADSL use, which I think is about
£70. Think carefully before removing your Home Highway as you loose your second line and number and
your priminary number is not necessarily ported back to your restored POTS. If that 'other' Highway
number is used for a fax number, do you need another POTS line? We are now into spending out close
on £150 before factoring in ADSL connection charges!

There is "managed conversion" for such a change. If ADSL isn't usable on
the line, the BT Engineer makes good ISDN again and no fee is charged. I
think you'll find plenty of people discussing this for the past 2+ years,
in u.t.b and on www.ADSLguide.org (forum). Peter Morgan.

Does the 'managed conversion' fee cover the ADSL setup such that only one
fee (of how much) is payable ? From what another poster suggests, there
would be a fee for the conversion and then a fee for ADSL setup on top...

I know that could be the case if one simply converted from HH/ISDN to a
DEL and then separately asked an ISP for ADSL, but surely part of this
managed conversion is to lessen charges, as well as returning ISDN if
ADSL cannot be provided. Thanks for any clarification... Peter M.

If you are lucky enough to get ADSL, you will be charged by BT for re-
connecting your analogue line. This is despite BT saying in your
contract there is no disconnection fee for ISDN. IIRC it's about £50.

Fee for reconnecting analogue + the ADSL connection fee.

Nope... managed conversion just means you have very little to do in
contacting BT etc.

The charges made by BT are just added to your bill so no need to find
the extra money there and then though.

As they say I have read the back, seen the play and the film etc etc. The statement above is
neither true or untrue. Basically:
1] If you decide to discontinue your ISDN service, then there is no fee to be cut off [all
outstanding charges have to be paid of course] and usually you get a rebate on the line rental that
has ben paid in advance.
2] If you decide to convert the ISDN line to a POTS then there is a charge to cover BTs cost of
sending an engineer out to your property to remove trhe termination unit and place a master socket
on the line. There's prbably some work to do at the exchange as well. Interestingly the charge
roughly equates to the installation of a new line. I don't think that is unreasonable for BT to
raise such a charge.
3] A managed conversion of an ISDN line to POTS only saves you money if the line fails the ASDL test
since the line is restored to ISDN operation at no cost to you. If you took option 2 above and the
line was unable to have ASDL then you would have to pay a connection charge to have ISDN put back.
This charge can be hefty depending on which connection option you choose.
4] Remember that in some cases you may have signed up for a long term contract for ISDN in return
for a reduced line rental. You still have to pay the rental of the "removed" ISDN line if still in
that contract period. This has caught out many people in the rush to convert to Broadband.
5] There is no guanatee that the primimary number of the ISDN line can indeed be the number for the
POTS service. Bit of a bugger to have reprint your business cards eh?
6] Youy may need to install another POTS line to serve the equipment [eg FAX machine] that was on
the "other" ISDN line.
7] With your POTS service now suitable for ADSL a connection charge is payable. That's £50 + VAT but
it is up to each ISP to decide if that base price is higher or lower than that figure.
8] It's your shout which ISP you go with, some are good, some are ugly and others are truely awful.
Add into the equation those ISPs that are not entirely honest in their advertising blurb [Broadband
IMHO starts at 512] and you need to carefully consider who you give your business to.

ISDN is much more profitable than ADSL.

The fee is £50 - it does not cover the ADSL setup as well.

Not as far as BT is concerned.

conversion with PlusNet. A very simple process and it works very well.
According to the engineer who did the conversion, he said that a good
ISDN line usually gives a good ADSL line.

They also cannot test a line with ISDN on it. Suggest you approach a non
BT ISP who do managed conversions. If it does not work there is no
charge to you and everything is re-instated.

Other people in my locality have ADSL, can anyone suggest
Me too - Plusnet managed the conversion from ISDN (Home Highway) to ADSL.
BT charged £50 (to my phone bill) for the conversion from ISDN to POTS. The
ADSL activation fee was paid through Plusnet.
BT told me that if they couldn't get ADSL to work they would restore the
ISDN as it was before with no charge.

I am 5.5km from the exchange, and was just within the limit for 1Mb (57-58dB
attenuation).

One advantage of this route is that a BT engineer attended and installed a
filtered faceplate - no need for microfilters everywhere!

Been there, done that. BT will tell you its not possible because they
test it, find "incompatible equipment" on the line and fail it, the
"incompatible equipment" being their Home Highway box! BT support just
didn't have a clue. I eventually found out about "managed conversions"
and the next challenge is to find someone that does them and knows what
they are. I used Nildram but I had a job to talk them through the line
failure being ISDN they were supposed to "managed convert". They tried
three time coming back to tell me each time the line had failed and
having to be told, no, the ISDN box failed it, go back to BT and tell
them its ISDN and a managed conversion. On the fourth attempt they
managed it. After that it was plain sailing. BT engineer turned up,
took the ISDN box out, tested the line to 2Mb without problems and left
us connected to ADSL. Its not easy but it can be done.
