Simple telephone wiring diagrams??
Posted 19 September 2006 - 08:02 PM
The master socket for out phone line is in our bedroom and the slave socket is in the living room and I want to use the slave to plug my router into.
So, first question is, why is the colouring of the cable supplied to the slave socket completely different to the cable going to the master socket?
The cable fed into the slave socket (but not connected to anything) has simple blue, red, gree, orrange, white, black, etc colour cables. Not like the striping cables found in the master socket.
So, is ther an easy way of wiring this up and does anyone have a simple link of how to wire this up properly??

Oh and the DIY expert was RILEYS who are contracted by George Wimpey to sort the BT work. When we moved in her it took BT 3 months to figure out that we had no telephone wiring!!

May be better running a cordless phone off the slave, and using master for bb /ubbthreads/images/graemlins/EEK2.GIF

So, on looking at the wiring to the master, the BLUE pair are connected to connectors 2 & 5. Is this normal? Nothing else is connected.

See my earlier link.

Usually (but not always) Orange and White are the active pair and go to connections 2 and 5. In some master boxes (such as the type with a removable front section) they go to two connectors marked A and B.

2- Blue White (A'leg earth)
5- White Blue (B'Leg battery)
3- Orange White (bell ring wire)
4- White Orange (this is earth recall wire and not require in home use)
Providing from the master socket the cable in 2, 5 and 3 is repeated to the secondary and on sockets, it will work.
Cable type to master socket could be external (overhead or underground) and will be black sheathed. Only 2 cores will be terminated at 2 and 5, The third wire, the bell wire must be wired to 3 at the master, going to each other socket, otherwise incoming ring signal won't be there.
Internally the cable is CW1308 which is 3 pair stripped colours, White- Blue + Blue white (1st pair), White-Orange + Orange-white (2nd pair), White-Green + Green-White (3rd pair). The 3rd pair is normally spare and is use for maintenance purposes (a failed 1st or 2nd wiring pair).
Telephone cable is solid core 0.5mm size, frequently contractors pick up the wrong cable type and use alarm cable which has a different colour range for it's cores.
This doesn't matter, since the alarm cable tends to be stranded 0.75mm cores and will not drop or weaken a BB signal, some might argue that since alarm cable is not true twisted pair design it is a poorer cable medium. On longer runs it might be, but in a domestic situation there's no problem.
Only problem being that alarm cables, because they are stranded sometimes don't cut cleanly with a IDC punch down tool (krone tool) on the line jack terminations.
A simple solution and common for DIY is to use line jacks with screw terminals rather than IDC punch down terminals.
Hope that helps /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/169144-ok.gif

And where do I get one of those wierd IDC tools from??

Might be easier and cheaper to ask Maplin for some line jack sockets with screw terminals.
You could get a throw away IDC tool, about 50p from Maplin. This punches the cable in to the IDC, but you will need to trim the spare cable with cutters (or nail scissors) since the throw away item wont's have the cable cutting bit.
If you don't have a Maplin, it's (the krone tool) a borrow off any IT cable tech (if you have one in office) or a visit to a independent Telephone shop- which most larger town and all cities seem to have, for either a throw away or the full monty /ubbthreads/images/graemlins/169144-ok.gif

Otherwise use an old loyaly/credit card. I doesn't do the card much good but works fine in an emergency.

and to this master socket, the Blue/w cable is attached to terminal 2 and White/b is attached to termainal 5
And the Slave socket in the licing room looks like this one, so I have connected the Blue to 2 and White to 5. And ZILCH!!
