Checking line lengths

With a view to buying houses, I've been using BT's ADSL availability checker
at http://www.bt.com/broadband . There seem to be four possible results for
ADSL-enabled exchanges. Does anyone know what the typical line lengths are
for each result and are there any other results that I've missed?

Also, have I got results 2 and 3 in the right order? Result 2 only says
"may be able" whereas result 3 (like result 1) more positively says "should
be able". Result 2 mentions long line lengths but says "up to 2Mbps"
whereas result 3 says "not be possible to provide the 1Mbps or 2Mbps". It
is therefore not clear which result indicates a shorter line length.

RESULT 1

Good news! Your exchange has ADSL broadband, and our initial test indicates
that it should be possible to provide ADSL broadband on this telephone line.

Our initial test on your line suggests that you should be able to have an
ADSL broadband service that provides up to 2Mbps download speed.

RESULT 2

Your exchange has ADSL broadband. Although the length of the telephone line
between you and the exchange is quite long, you may be able to receive ADSL
broadband.

Our initial test on your line suggests that you may be able to have an ADSL
broadband service that provides up to 2Mbps download speed.

RESULT 3

Good news - Your exchange has ADSL broadband.

Our initial test on your line suggests that you should be able to have an
ADSL broadband service that provides up to 512Kbps download speed, but the
upstream bandwidth will vary according to the length of your telephone line.
It will not be possible to provide the 1Mbps or 2Mbps ADSL broadband
services.

RESULT 4

Your exchange has ADSL broadband. However, the length of the telephone line
between you and the exchange is too long for ADSL broadband. However, we are
continuing to look for alternative technology solutions and will keep you
updated with developments as they happen.

<3.5 km loss <41 dB

dodgy one this, might be an AA code line ie they don't know, otherwise
why say its a long line then raise possibility of 2M ?

between 3.5 km and 6km ie 41 dB < loss < 60 dB

likekly ~6km or greater, or loss >60 dB

use groups.google.com search for BT_ADSL_CODE to understand what's
behind it. Or visit

Thanks very much for this. Is it possible to look up the BT_ADSL_CODE on a
web page? Where does the tool at http://www.jbod.net/adslchk/ get its
information from?

you can find it in the source code of line checker result pages like
the one at www.bt.com/broadband (thi sis mentioned in the FAQ on the
subject I think)
