BT Filterplate Questions

[coolertech]

Hi, I have a filtered faceplate that the BT engineer fitted a few years ago, it says on it ADSL V1.0, it has the two sockets on the front (one for phone and RJ45 for modem) however i'm not sure that the rear extension connections are filtered because I'm getting lots of crackling on the extension lines which are connected to the rear of the filterplate.

On the rear of the filterplate there is 3 IDC connection points, and not 6 like on the new V1.0 plates.

Would i be correct is saying that this might be a very old one with non filtering of the rear extension connections?

The rear connections will filtered, but it is possible it has developed a fault. Remove the faceplate and plug a filter directly into the Test socket. See how it is from there. It is possible a fault on the line is causing the noise.

No it is a normal filter faceplate, and the rear connections are for normal telephone extensions, not BB.
They will be marked 2, 3, 5.

ive got two telephone extensions going into 2 and 5 connections for the telephones upstairs, the BB router is plugged into the RJ45 socket on the front of the faceplate, then my downstairs phone and sky box is plugged to the front of the filterplate also.

I get no crackling on the phone downstairs, only crackling on the upstairs extensions which are wired into the back of the filterplate.

Loose connection? Does it crackle if you wiggle the wires? The 3 way version has a white IDC block and connections marked 2,3 & 5, the 6 way version has a blue IDC block with A & B unfiltered connections on the back in addtion to 2,3 & 5. Both have ADSL V1.0 on the front!

no mate, i've tried re-inserting the wires with a IDC tool and i still get the crackle on the extension phones, my feeling is that the rear connections are not filtered, so what i'm going to do tomorrow is buy a couple of microfilters and put them on both the extension phone sockets, if this stops the crackle then I will have to buy a new faceplate.

so just to get this right, there is a ADSL V1.0 Faceplate that filters the sockets but not the rear IDC connections yeah?

If this is so all i will need to do is try the microfilters then buy a new ADSL V1.0 box that DOES filter on the rear IDC connections

Both versions have filtered connections on the back(2,3 & 5). If you look at the faceplate you will see plastic tabs, if you push these out the cover will come off, the design is two piece-it sounds like it may have become loose or maybe a dry solder joint on the PCB.

Did you check the connections at the extension socket ends? Crackling would not usually be the symptom of a faulty filter, Unless as RiD says it is a bad solder joint.

Remember, you could have your Extension Wiring running under Carpets, which could cause noise,
