Hey guys,

I'm switching over 1 line of a telephone system in a business that has a pbx system to provide adsl service.  I was wondering if instead of running a telephone wire to the fax (that is sharing the line with the dsl), if i could splice into the connectors next to the pbx system  so I don't have to run another wire.  BTW- this line won't be connected to the PBX.  Thanks.

My response, without researching, and if I am correctly interpreting your intentions, is that if you are not going to use this line and its wiring redundant, then go ahead and 'splice it and see' - If the cable or your splice is 'poor' then you will have to run another cable, but you have lost nothing in the process (apart from 10 minutes of fiddling).

Both POTS and ADSL use twisted pair copper for the final mile so I would assume a fair chance they have some degree of compatibility?

NOTE: BT states that PBX lines are not compatible with ADSL - But then gain BT would freak if it saw how my converted RJ45 cabling was thrown into my ADSL line, However I am not a business and do not care if it packs up on me.

Just ensure the PBX line you are going to use will NOT plug itself back into the PBX system in any way shape or form.

First of all, hippy, thanks for your prompt response.  Considering my lack of knowledge relating to PBX systems (and the lack of manuals available on the web), I am having a hard time recognizing which set of wires run from the last junction of wires to the fax .  Is there a simple way to identify the line without specialized tools?  Also I'm not sure what is meant by wiring redundant.  What does that mean?  I do understand your suggestion of making sure it does not run back into the pbx system.  Thanks for all of your help.
