Crackle on landline phone

kwikbreaks

If the noise only apears with the router plugged in then, assuming no filter fault, it's going to be a line fault. What happens is the ADSL signal gets rectified by a dodgy joint in the line (just like the old crystal set radios) and the varying ADSL signal level becomes an audible crackle. I had that exact same fault. After 5 visits from the boys with muddy boots I gave up and swapped to VM cable. I've moved back to FTTC since and the new line is fortunately fault free.

Good Luck.

It'll be the same line from the cabinet to your house. This just means the fault was on the exchange side of the cabinet ... FTTC is fibre from the exchange to the cabinet, then traditional copper pair to the property.

(The copper connection from cabinet to exchange may or may not be the same as before. Your phone connection still uses copper all the way from your property to the exchange).

I've been out to cool off and thanks for recent posts. In a min I will take you back to my post No 39, but before I do, I've been thinking.

Crystal clear phonecalls when both router and phone inserted in FILTER which is inserted in FILTERED FACE PLATE as shown. (I appreciate that's a contradiction, but was trying anything.). But as stated, no internet connection was possible. It was only when the router cable went back into the FILTERED FACE PLATE directly, that internet was restored, but then the crackle resumed.

My walk/think told me that I should forget the (dangly FILTER) and try as many router cables that I can lay my hands on, in case the current one has a fault.

That was my intention, but now have your posts to explore.

Yes espresso, it's like that. You say " if you plug your router into the ADSL filtered phone socket, then the internet obviously won't work".
why not? if the phone is in IT'S slot and the router is in IT'S, then surely that seems right?. As for trying another, I have a modem and router and am unsure which is which. (don't laugh). As I say, cables will be tried.

Bod1467, I think it was you that told me about removing the faceplate and trying the 17070>2 before, but I am with talktalk and if I remember correctly, it didn't have that option, but will try again. Then I will try you other recommendation "What if you then plug in a filter to the Test socket and connect the router? Are calls still quite and the internet works?"

As for the dummies bit and yours kwikbreaks, they will be next to try. Currently my abdomen is giving me some discomfort from all this bending about (major surgery following bowel cancer), so other than seeking out the cables and mentally preparing myself to achieve a result tomorrow, I will remove the "other cable", unsure if it called the adsl or router cable, so that any calls are clear tonight. Thanks for your perseverance. It's much appreciated.

Whilst I can hear a crackle, you might hear the sound of breaking glass as I throw the phone though window soon!.

OK, a step nearer. We have a dual faceplate. The phone plug goes in separate to the other plug and have always thought a filter wasn't needed, but today I inserted one into the phone slot on faceplate. Into that both phone and router were inserted...........................


Success.! crystal clear phonecalls.

Then I started up internet only it wouldn't?

Despite many times trying, no connection. I removed the router plug from filter and put it back in faceplate.............internet connected but crackle returned.

So, is it a faulty faceplate of router cable? Is there a "right" end to these things? and should I try other router cables just in case the one I'm using is faulty.

You stated that you plugged your router cable into an ADSL filter that was plugged into the left hand socket marked PHONE.

The PHONE socket on the faceplate is filtered to prevent the ADSL frequencies interfering with the phone audio frequencies, so with no ADSL signal, your broadband will not connect will it!

The ADSL socket is unfiltered and connects directly to the line which allows the ADSL signal straight though to the modem/router.

As you had "crystal clear phone calls" when using the additional ADSL filter plugged into the faceplate PHONE socket but no internet, why don't you try moving the router cable back to the ADSL socket and use the additional filter for the phone?

Hi. Today with the desk pulled out, I tried four different adsl cables in the appropriate socket on filtered faceplate and tried a phone call. Each time a crackle.

I then removed filtered faceplate and inserted a filter into the phone socket and inserted both the phone and adsl cable in the appropriate slots in the filter, clear call and internet connection.

This told me that the section of filtered faceplate I had removed, was the offending area to concentrate on. I unscrewed a casing on that (which revealed a lots of soldered connections which I blew in case it was dust) and replaced to that front half (filtered faceplate). This made no difference.

I have now formed the opinion that it is THIS front half of filtered faceplate that is causing the crackle.

PS, I have now spoken to TT and they are carrying out line tests and thus far, two text messages have come though by them. The second is to say the fault has been passed on to the engineer. Will update as and when.

Maybe or maybe a different pair. I was on cable for about three years and the old line was totally dead. I must admit getting the same line and a return of the fault was a worry at the time. I don't use the line for voice now either - I kept the VOIP package I was using while on cable. It gives close to top fibre rate with a 350m+ last leg so I think that bit must be fault free although of course it may well have always been. Each of the Openreach blokes claimed to have swapped out a different part of the line - if they did it was all different with joints remade yet the fault persisted.

Sitting here like a lemon unsure what to do. Just dialled 1471 to see if the crackle is still there, but clearly they are doing something as I was cut off and engaged tone was heard.

Just dial a 0 - that will silence the dial tone for a time.

Long conversation with TT. they wanted to know how long it's been going on. Was able to tell them I first posted here april 2014 and it has been on/off since. Desk back in situ, front of faceplate off, phone connected directly into test socket with filter hanging. Both phone & adsl pushed into that. They will keep me updated by text.

I'm guessing that you, like most of the UK, had a fair bit of rain recently. Perhaps the duff joint is drying out again leading to the improvement you say you are getting now. I'd personally check with the filtered faceplate again to see if the noise returns and prove that is the problem.
