Finally resolved my ADSL connection problem...all due to the phone filter which I didn't have!!! DOH!! Weird thing was my ADSL connection would work 3-4 days out of the week, thus I wasn't really troubled since I could get my emails at work.

Make sure each phone/fax/pots modem/alarm system runs through a filter. Everything but the ADSL router needs one. :)

If I were to plug my phone into the line without one, What effect would it have?
 
the pots filter prevents normal telephone equipment from interfering with ADSL.

someone I know works for a UK ISP and the first thing they do when troubleshooting 'strange' problems is to replace the pots filter. 9 out of 10 times the problem is caused by a faulty pots filter.

THIS PAGE explains the function of micro-filters quite nicely.

The line from the exchange to your premises carries direct current to power the telephone, low frequency alternating current to ring the telephone, voice frequency conversation signals, and high frequency DSL signals. The DSL signals are up to ten times the voltage of voice and use much higher frequencies than ordinary telecommunications devices (telephones, fax machines, modems, alarm systems, etc). The filter protects these devices from the DSL signals.
 
Ah, nice. I expected that the DSL would make a "noise" on the line that would make dailing difficult, but this was not the case. Phone(s) works fine without the filter. So the function is more that of protection. Noted
Thank you!
