Hi,
I don't think I've seen the following information on this web site so I thought it may be useful as it's often mentioned - it's how to find out your line length from the exchange.
I found it on another site but have lost the URL, I still have a record though!
Distance From Exchange
Dial the line test number 17070. Then press option 3 (fast test), then press
option 1 (to say you are authorised, don't worry about 'not being officially
authorised'). The press option 2 (Traditional Fast Test) then finally press
2 for Ring Back Line Test. Then put the phone down.
You will get called back by the test facility within about 30 seconds, one
of the bits of information given will be distance from exchange (in
kilometres).
Please note though, not ALL exchange test systems have this information.
Most do, however some dont, and if youre unlucky to fall to the latter, then
you'll have to rely on theaa.com to give you a "rough guide" via point to
point postcode search.
