A tag to indicate the location of telephone exchanges. This is of importance to ADSL users as the distance a property is from an exchange often dictates the speeds attainable or even if ADSL is possible.


Applies to nodes only

  • key=man_made value=telephone_exchange


A telephone symbol with a double border is proposed.

I dont see why not. Samknows Broadband site has it at and can see it being no different to substations. John1981 23:27, 28 February 2008

The distance from the DSLAM (which is typically at an exchange building) is what affects possible ADSL performance; however, this is almost never going to be distance as the crow flies. Telephone cables have to find their way to the customer's premises via a twisty set of ductwork, overhead cables and the like. Admittedly, living next door to the DSLAM is likely going to be better performance than if you're thousands of metres away. Welshie 11:13, 29 February 2008 (UTC)

Welshie, I agree, the cable is never as the crow flies but I believe the information is relevant if nothing else for a rough guide of the distance. John1981 14:49, 29 February 2008

  • In Germany those are also located in small boxes on the sidewalks. They are called mini- or outdoor-DSLAM but do exactly the same. Wikipedia picture -- Fröstel 15:25, 29 February 2008 (UTC)
    • I think this is an great Idea. Should we distinguish between Serving area interface [1] (Kabelverzweiger [2]) and (Outdoor-)DSLAM [3]? --DB1BMN 01:02, 5 August 2008 (UTC)

The german exchange points were imported with the Tag man_made=MDF.--Zuse (talk) 19:57, 11 April 2013 (UTC)
