What could be causing this in my house?

[nikonuser11]

Sky BB and sky talk, the phone line is either non existent or incredibly crackly, and when someone phones in the BB disconnects then recycles to connect again
Sky say the line is testing perfectly and when I connect into the master BT socket the line sounds fine.
Sky said disconnect everything on the line which I did but still either no dial tone or very crackly dial tone (connected 3 different wired phones)

Any ideas what to try next?

Hi,

If everything else is disonnected, and the line is okay at the master socket, but not at the extension then it sounds like the cabling between the two sockets could be the problem. I would unscrew the faceplate at either end and check the connections are okay.

Cheers,

Neil

In virtually all cases of this sort the problem is a fault within the home in the internal phone wiring. It can be caused by damp, earth leakage, physical disturbance of the wiring, vermin, pets, even simple old age. Another source of trouble is failed micro filters which have a limited life. If even one fails your system will function poorly

The answer is to eliminate the connection between broadband and voice circuits so that the broadband works to its best, and then identify and remedy the fault on the voice wiring

The easiest way is to fit a face plate to the master socket so that the broadband and voice circuits use different plugs

Details and lots of advice here:-

done that and wiring is fine at master socket and extension
so what now I'm really stumped at what to do now short of paying Sky/BT a fortune to come out and check it all but the house was fully rewired only 3 years ago

If the problem goes away when you are connected to the TEST Socket of the Master Socket then the problem is with your Internal Wiring or a device connected to it. (BTW, contrary to a previous post, most problems like this are external to the dwelling and are caused by faults in the cable joints of the pair that connects the dwelling to the Local Exchange.)

Having said that,the Internal Wiring is your responsibility, not your ISP's and so if you call them out to fix it, expect a large bill.

So, with all devices disconnected, starting at the back of the faceplate of the Master Socket ensure that only the following wires are connected: Blue & White to connector 2 and White & Blue to connector 5. NO OTHER WIRES ARE NEEDED NOR SHOULD BE CONNECTED. Now go round to each Extension in turn and do the same. Connect just the router to the Master Socket. If the problem remains you will need to remake the Extension Connections but you will need the proper tool.

Now connect each telephony device in turn to ensure that the fault is not caused by one of them e.g. Sky boxes are notorious for casing this fault.

Thanks Beerhunter, thats great advice (don't have the tool though so will skip that part) Sky box was disconnected from the phone line or do you mean disconnect it from the mains as well?
You also said "most problems like this are external to the dwelling and are caused by faults in the cable joints of the pair" how do they find that out as my wires are all new in the house so maybe it is external but they say the line tests fine

If they are adamant that the line tests fine, re read my post of yesterday 9.00

If you disconnect all but the broadband in to the test socket and it works ok then it MUST be the internal wiring or microfilters causing the problem, even if the internal wiring is only 3 years old

And if you connect one known good telephone in to the test socket and that works ok then that confirms the BT line is working well and your house wiring has a fault

In such a case you don't need to call out anybody. Just ensure that all the microfilters are working ok (by substitution with known good ones) and carrying out checks detailed in link provided

1. Sky box was disconnected from the phone line or do you mean disconnect it from the mains as well?

2. You also said "most problems like this are external to the dwelling and are caused by faults in the cable joints of the pair" how do they find that out as my wires are all new in the house so maybe it is external but they say the line tests fine

1. Just from the line. BTW, unless you use interactive or have multi-room there is no need to connect the Sky box at all. They can cause trouble and so unless the above is the case, I'd leave it disconnected.

2. As has been said, if the fault goes away when you are connected via the Test Socket you have an Internal Wiring fault. The fact that you have new Internal telephone wiring is neither here nor there in my experience. I have seen extension wiring done by sparkies that was just plain wrong. I have even seen a manual for sparkies that was wrong as well.

ok thanks guys, will try all this again tonight and report back to either give you all a big pat on the back or cry and ask for more solutions without paying the BT guys a small fortune

Update, disconnected everything then connected a corded phone into the test socket behind the faceplate of the master socket and still getting all the crackling noise so it looks like your right beerhunter and it's external to the house and at the exchange- Sky said the test on the line still passed but will escalate the fault to second line and they will investigate over the next 72 hrs..
Hope they sort it soon, will report back when they do, thanks for all the useful advice chaps
