      BT Engineer has called round and checked the line, he did say it sounds faulty and went off to the exchange never to be seen again.

      Nothing came of it and I assumed he did something or BT would of charged me.

      Whats a TDR?

      Regards.

      Have BT been out to the house and checked out the line with a TDR?

      Sorry about the TLA (whoops at it again, Three Letter Acronym).
      My mate in Stoke had terrible trouble with Tiscali, and eventually had the BT man out to check the line that way and they swapped him on to another line back to the exchange which resolved it.

      Re: Going bald slowly......

      For the informative:

      Bug sweeping of telephone, electrical and data lines, in particular when the analysed cable is of a length of hundreds if not thousands of metres, can only be conducted by means of a particular instrument called Time Domain Reflectometer (TDR). This piece of equipment can check any type of line (even under power) and indicates on a display screen the presence of abnormalities (short circuits, open circuits, series or parallel connections, inductances, capacities, etc.) and/or parasites.

      Our digital Time Domain Reflectometer has a range of over 11.000 metres with a localization precision of about 20/30 centimetres. This instrument is indispensable when the examined line is very long (try to imagine the route that a cable follows from a telephone switchboard in the basement of a large building to a phone located at the top floor) and not easily accessible (passing through walls, third party property, roads, etc.).

      Trend who have been in the business for years, we used their BERT testers on our then advanced 75/1200baud modems, have some nice application notes:
