My landline has been suffering from a lingering death for a couple of years. It's become noticeably noisy on analogue calls, and the ADSL sync speed has been dropping.
An SMS from AAISP two days ago saying '###No Carrier' marked it's final demise.
No dial tone.
Yay! A hard voice fault. The one thing that BT will pay attention to. Finally, BT will fix the bloody thing.
And so they did.
Two days later, the dude appeared, we had a chat, and off he went to ferret around in holes in the ground. A few hours later he returned, triumphant. 'Try it now!' quoth he. 'There were a great multitude of faults on your line, and I have vanquished them all!'
And lo, so it was: the line was quiet, and the ADSL sync speed had gone from an uncertain 17Mbit to a solid 27Mbit, never before seen in these parts.
