How to Calculate your distance from an ADSL Telephone Exchange

Which Exchange are you on?

Click on the link for your state, and find your Exchange in the list.

Find the Cable distance from your house to the Exchange

The next step is to make an approximation of how long the telephone cable is between your house and the Exchange. The easiest way to do this is to use Google Maps.
Go to Google Maps

Search for the address of your Exchange

Then using the Google Maps travelling instructions, click "from here", and then enter your home address as the "to here" option. This will then give you driving instructions between the exchange and your house. Note in the left hand panel that the total distance travelled is available.

Now this is just an approximation to how long the cabling is, however it is a much better approximation than "as the crow flies".
