Re: Poor BT Service on Phone Line & going round in Circles

Out of interest, has any phone line ever failed the BT/Openreach line test? I've experienced lines that are unusable due to faults but will still pass a line test.

 

The only times I've seen one fail a line test was when there was a massive underground cable fault and it took OR a week to get our business line back

Thought you might like to see how the line tester works.

Very drole I'm sure.

 

My own suspicion is that the line test simply involves the exchange equipment checking the resistance of the line to the test resistor in the master socket. If this value is within a range then the line is deemed OK.
