Hi,

I consider myself to have a good understanding of home wiring, master filters, xdsl etc, I am a noob here so hope i have posted this in the correct place?
I have had bad packet loss on my connection for sometime but have not been experiencing dropouts of any sort, I have contacted my ISP as i had checked my
stats at my modem and carried out some tracert tests and find certain hops inactive.

However my ISP insists it is not there problem as they can have done tests (DSLAM) and can confirm its reaching my house ok, anyways i decide to upgrade my
house wiring and hardware as Fibre for me is too long to wait.

I plan to run cat6 from the demarc to a patch panel/switch/modem, I am planning to bin the BT sockets and upgrade to RJ45 wall plates, I wont need a master filter as im on a naked
connection and plan to split the line through the cat6 cable this is not an issue? so i got up in the roof where my demarc is and found two pairs of wires one pair not connected at
all and one pair connected to the phone line that i am currently running off.

Both pairs have the same colour wires i.e red black, so i am assuming that the correct pair has been connected to my internal wiring for me to have a sound connection, It
turns out my connection is far from good, Im not sure how to proceed from here as i would like to think the correct pair is connected how can i be sure are there any simple tests
i can carry out?

Ive looked at images of other wiring diagrams at the demarc and colours are specific and colour coded for ease of understanding.

Any help would be appreciated.

Cheers

I'm guessing that's a typo and you meant Cat6 rather than RG6.

Probably what you want to do is replace the wire from your demarcation point to a single jack with Cat 6, as you've said. That might solve your connection issues, particularly if the current wiring is a mess. The red + black pair that's currently in use can connect on the blue + blue/white pair in the Cat6. The other 3 pairs are left unused.

That single jack where the phone line comes in could be a single port on a patch panel you have set up. Your modem/router would connect to that. You would then have the other ports on the patch panel set up, each which a new Cat6 cable running out to each outlet (two for a double outlet) to be patched into the ethernet ports on the modem/router. In other words, a star wiring configuration as shown here: https://www.chorus.co.nz/file/18484/minimum_communication_cabling_requirements.pdf

You would only be able to reuse the wiring to your current BT jack points for data if it is already in a star wiring configuration, and is at least Cat5. That would probably only be the case if your house is modern and the wiring has been installed recently. Even then, it is more likely that the points will be daisy chained, rather than in a star configuration.

If the wiring is already in a star configuration and at least Cat5, then you could replace the commoning hardware (the point at which all the wires are connected together) with a patch panel, one wire connected to each port. They could then be patched for use as either phone or data.

If the phone jacks are daisy chained, you can pull out all your existing phone jacks and replace (this is what I did). Alternatively, you can connect the daisy chained phone jacks to a single jack on the patch panel, and then install new faceplates for the RJ45 jacks. That would allow the existing phone jacks to be livened up in the future, if you had a voice line connected, or signed up for VOIP.

Hopefully that all makes sense and answers your question, but if not, feel free to post back.

Pictures would help :-)

Normaly demarcs are on the outside of the house not the ceiling. So what your looking at up there may be just a joint and from the sound of what you have described it is likely to be old school (1960s/70s) aerial or soft copper single pair cable that has been cut into and rerouted into later 70s/80s cable to the jkpts.

As has already been commented on if you have some form of DSL on the jkpts then its connected.

Is your House feed from the road via an aerial cable? if so -

To bypass all of the existing wireing - run a CAT6 all the way from were the feeding cable comes into the ceiling down to where you are going to put your patch panel - leave a coil or two at the roof end and useing two port crimp connectors connect the incomeing circuit to a single pair (normaly the blue one ) on the cat 6 and terminate the other end on a RJ45 or on your panel (just the single pair). If required later - a master spliter can be added to the pannel. Why leave a coil - so when the aerial cable is replaced and the chorus tech installs a demarc (like they are supposed to do) then they can pull the cat6 through to that point and reterminate it. A master spliter could also be added here and a secound pair in the cat 6 used to take xDSL down to your panel.

Run multipule individual runs of CAT6 cable to where you want to take data and or voice from your panel to your new faceplates and remove the old school phone cableing and BT jkpts as you go

Go to Cables Direct

search for these tools:

to join ethernet to RJ45 sockets:

"Punch Down Tool" (Krone type)

to join ethernet to incoming phone wires (or master filter):

"Gel filled Joiner"
"Compression Tool"
"Swivel Blade Cable Stripper"

Most if not 90% of RJ45 IDC connectors are designed for AT&T 110 punch down tool not a Krone punch down (as they originate from an American Standard)

100% of BT Style IDC connectors use a Krone punch down tool (as they originate from a English Standard)

ONLY connectors marked as KATT (Krone & AT&T) can be used with either

Use the wrong tool and you risk either breaking the tool or the IDC strip

(IDC = Insulation Displacement Connector)
