shame you didnt have a router/modem with an accessible 'busy box', these are usually found in
(but not limited too) modems with 'unlocked' Broadcom chipsets
(unlocked meaning the ISP or Manufacturer's firmware does not deny telnet access to the modem), you get way more information about your connection and can be used to help resolve problems, the
preferred modems of regular kitz users usually tend to be one of the various
Zyxel models or the
Huawei HG612 3B, you can run monitoring software such as DSL-stats, HG612 Graphing Scripts or RouterStats etc...very handy.
Regarding the JDSU picking up noise, when the engineer arrived for testing was the connection down then? as you say the engineer couldn't find a fault .. if the fault wasn't 'active' when the engineers testing then it probably won't pick it up no. I'm sure one of the engineers on this forum will be able to elaborate on that some more.
Is the NTE5C the only phone socket in the property? I'm guessing so otherwise you would have said. I will say that the NTE5C is carp, it's very well documented as a poor design and a few people (myself included) have had negative effects from using it. I know you had the problem before it was installed...
but if it were me...I would be putting the 5A back at least until the problem is resolved, then I would be using DSL-stats with before and after readings
(over time too) too see what
(if any) impact it has. If I had left mine on it's quite likely that DLM would have kicked in and applied Interleaving and INP, this is because my errors went up 10 fold on the NTE5C (and that wasn't the only issue).
when you say "line not proven right" do you mean the type of fault the Line-Test is picking up won't allow for anything other than an FFTC1 visit? maybe you need to ask the Sky rep to 'over-ride' it, then they can send out any engineer
next time it happens grab an old AM/MW radio and follow the instructions below
~ Is there anything I can do to try track down & identify the source of REIN?
If you suspect there is something interfering with your broadband, get an AM/MW radio and tune it to 612KHz.
If you hold the radio next to an LCD screen for your PC as an example you would hear a distinct noise. This should fade away if you move the radio a quarter to half a meter away. Hold it by your modem/router and you'll hear the DSL signal.
If you get a distinct noise enveloping a larger area, then this may be picked up by your router causing an SNR problem (or even drop of sync). By using the radio you may be able to get an idea of where the noise is coming from. Switch the suspect appliance off & retest your DSL broadband connection. By distinct noise you're looking for a clear buzz, whistle, clicking etc. White noise or a general shhhhh noise is less likely to be the cause of the problem, same as any radio broadcast. (In the south of the UK you may hear a French radio station from around 612KHz.)
Be aware that any noise heard on the radio is not always affecting your DSL connection, and you may still have REIN issues in the area which will not be picked up @ 612Khz as REIN is often notoriously difficult to pin-point. This method can be a bit hazy so don’t rely on it completely by any means.
Xmas lights are a classic cause, as are noisy electrical appliance with a long length of wire which acts as an antennae. Sometimes you can cure it with a ferrite sleeve (that small cylindrical thing you normally see along your monitor cable which doesn't’t seem to do anything) which you can get from electrical suppliers such as Maplin.
