How to connect...??

[whazza22]

Hi, Im installing a telephone line in a house and all I have is a black telephone cable coming through the bedroom window which was chopped off when they moved in.

Im assuming I need a telephone junction box to extend the cable to the required position.

Does anyone know how to connect this to my 2 pair cable?

The black cable has 3 reds, 1 black, 1 green, 1 orange and 1 white cable.

Thanks

Hi mate the three reds are stainless steel supporting wires. Your dial tone will usually be on orange White but sometimes will be on green black. Orange White is pair one green black pair two. You would extend this cable using internal telephone cable put orange White through to your blue with White rings and White with blue rings. This then gets connected to numbers 2 and 5 it's not polarity conscious

Ps you will need a telephone junction box internal cable and a master telephone socket if you use a secondary socket (extension) it will not ring

If that's the incomer from BT or whoever it will need a master box first at that point, before you can run slaves off of it..Details here...

If you want to run an extension from the master take internal cable from connections marked 2,3,5 to the same on your extension socket. Alternatively use a micro filter from a broadband line as this has a capacitor in it and will make the phone ring

to identify the incoming pair, look for 50v d.c. with a multimeter. these go to A & B or 2 & 5 on your master socket. either way round

Hi Guys, just a quick question on this issue. I was always under the impression that anything from the master socket backwards (including main cable in) was only to be tampered with by BT and anything spured off the master was ok to alter. Is this still the same theoretically?

 

[telectrix]

yes, but as it was cut, BT will charge for the repair. in the real world, as long as you can repair it OK BT don't give a ----

anyone know how to identify the cause of a hum.

Umm, what sort of hum?

Sorry couldnt resist

 

[martysparky]

good question as I don't think its mains hum on the line. I tried diconecting extensions from the master and still the same.

ooof!!

Disconnect everything except the service providers master socket. If it still humms the fault is on their equipment or network and they cannot charge to fix it. If humm goes away start plugging things back in. It could be a bit of equipment or even wiring.

 

[jmtisme]

Humm is usually caused by an earth contact. This could come from inside the premises or outside. Only way to find out is by testing as above

Dis connect the master front and try it at the test socket to eliminate problems with the master
