Now I’m not technical in a telephone or Broadband sense but I was a building services maintenance manager and engineer in my past and I do know a bit about systematic fault finding. I can also learn. I have needed to!
BT & I are at loggerheads over my BB service, which since the middle of December has persistently dropped out on most (but not all days). I have had 6 or is it 7 BB & Openreach engineers all visiting, doing their tests, and with the exception of one, saying they cannot find any faults with my equipment, the BT apparatus, or the Openreach cabling. I concede that the stats seem to corroborate this.
One engineer early on in the saga speculated that it might be my phone causing the problem , but it was only a guess. (But on the strength of his reporte BT have charged me £127.99 for his visit, despite not fixing my problem)
Guess or not I went out and bought a brand new BT Phone and answer machine, but of course the fault persisted: and it is now more than 5 weeks old.
The BT Home Type A I have found out has a history I believe of wireless connection problems and its transformer power supply certainly makes a great deal of noise at 610khz. This is the router, which I’m using at present, but in the past I have had similar problems with other routers. If my problem is REIN noise from this source why do I get some good days when the BB connection stays in sync perfectly well.
Whilst listening to the Rein noise from the Power supply the last engineer demonstrated how the sound of the router trying to re sync could be heard on the 610khz tuned speaker.
Now is this significant? The engineer thought it might be but was not prepared to speculate in his official report. If carrying out a 17070 – quiet line test at the same time, there is sometimes, but not always, a hint of a sound which seems to coincide with the flashing of the BB lamp on the router. I thought the engineer said that this was an indicator for an HC fault. Now HEC faults I know about and these are consistently nil / a very low number seldom above double digits and often zero. I did look up HC faults on the web and found a reference under iBurst which frankly I did not understand and seemed irrelevant anyway. My wireless connection being 802.11 not 802.20.
I’m grasping at straws here but if anyone can explain in words of one syllable first why my connection keeps dropping out, failing to reset until I use the phone to make a call, AND defeats the army of BT & Openreach engineers who are working on the problem I’d be very please to hear what you have to say. I am at the end of a long copper and aluminium line with a line att of 63dB & 31.5db pretty consitantly because I’m on a fixed BB at 0.97kbps the line being incapable of sustaining anything better.
