Hi guys,

 

I recently decided to check my wiring in terms of ADSL speed and I discovered quite interesting things:
I opened that box where a phone line comes into my house and there are four wires connected to my house (my internal cabling seems to be made of Cat5e/6 cable).

 

Kind of wondering why they provided four wires when only two wires are required for a phone and BB? (they are blue and white BTW)
Also on two wires (one pair - black and red) I found a ~48 VDC (+/-) to be presented and they were actually not patched to a wall socket.

 

So to summarize - four wires from underground are connected to four wires that go into the house. Two of them are patched to a wall socket and used for BB, the others two are NOT patched and just left wrapped around the Cat5e/6 cable in a wall socket but the have +48 VDC.

 

I also found that white cylinder attached to only one single wire. What is that - capacitor? Shouldn't it be connected to two wires? Should I reconnect it back (probably to a white cable?)

 

 

 

Can all the above make negative impact on my BB speed (I am on naked plan so no PSTN)?
Currently it is:
Upstream   Bitrate Fast        : 0 kbps
Downstream Bitrate Fast        : 0 kbps
Upstream   Bitrate Interleaved : 1128 kbps
Downstream Bitrate Interleaved : 10122 kbps
Downstream Noise Margin        : 6.000 dB (48 1/8dB)
Upstream   Noise Margin        : 5.5 dB (44 1/8dB)
Downstream Transmit Power      : 19.9 dBm
Upstream   Transmit Power      : 12.4 dBm
Downstream Attenuation         : 29 dB
Upstream   Attenuation         : 17 dB

 

 

 

I found a DSL calculator which told me that based on line attenuation I should be getting around 14Mb/s.

 

There are no other phone sockets there or at least I could not find them, but I live in a rented house so can't be 100% sure.

 

 

 

Thank you.

You would have had a second line at some point that is still connected at the Cabinet / Exchange.

 

The "White Cylinder" can be removed.





Hmmmm

If your landlord doesn't mind, you can go ahead and disconnect everything except the one pair you need. I did that at my place, there was a spaghetti of at least seven lines hacked in that went to sockets and whatnot all over the house, or possibly nowhere in some cases. Since I'm on naked DSL I just cut the wire before it even reached the junction box and ran a line directly to the ADSL router. Doesn't need a filter or splitter or anything, it's just straight from the street into the router.

So did it make your ADSL any better?

At best it would have been a marginal improvement, I don't remember any huge jump but it was also some years ago, I think there was a slight increase in performance. The main thing was that when you've got random lines running all over the place there's the potential for moisture to get in or noise to be coupled in, so it reduced the possibility of hard-to-find intermittent problems. In any case it didn't cost anything, and looked a lot neater afterwards.

Hey everyone.

 

About to start my journey on rewiring the house phone cabling. Before I put up some questions, is there a thread or post that has a list of current standards to be used when rewiring? Much like the VDSL Performance & Tuning thread which is a good read.

 

I have gathered some info myself like using RJ45 points, cat6(solid core) cabling and scotchloks to join wires but still have some questions.

 

Cheers
-
Jeremy

Scotchlocs, no only for 2wire phone circuits, not for any circuits carrying Ethernet.

Yes absolutely, for phone line only. Punch down block for data.

 

So the first step is to replace the phone cable from the ETP, currently it looks to be a single pair parallel wire as they join together in their own sleeves.

 

The lead in cable is over head. Do I need to ensure the wire gauge is the same between the Solid core cat6 and the lead in?

 

On a curiosity note, while walking around I have noticed there seems to be two types of overhead lead ins, one is a thicker straight wire and the other is a thinner but visibly twisted/corkscrewed. My guess is that the corkscrewed cable is the older style?
