I have an unterminated cat5e cable from my structured wiring patch panel that i want to connect to my bt master socket. Which colours should i connect to to the 2,3 and 5 pins in the bt socket so that i can then use any of the cat5 sockets elsewhere in the house as a phone socket using a rj-45 -bt adaptor
The structured wiring is all terminated normally colour-wise on the patch panel
Thanks,
Richard

Connections 2 and 5 in the BT socket are the only ones you need.
-
Thank you but,
......which cat5 coulours should i connect to those pins. I don't know which cat 5 colours the rj45 bt adaptor will translate to BT pin 2 and 5..
Hope you can help,
Richard
-
The normal colours for pins 2 and 5 are white/blue and blue/white.
-
Thanks you again but yes, those are the normal Bt colours.
They aren't cat5 colours, so short of taking the adpator apart which cat 5 pins should i use?
-
I don't know which cat 5 colours the rj45 bt adaptor will translate to BT pin 2 and 5..
That's an RTFM question surely?
i.e. read the spec of the adapter product you're plugging in the other end. :graduate:
Or put a meter on it and work it out yourself?
-
OK, I understand the question now. What you actually want to know is how the RJ11 - BT adaptor is connected internally. I think this (http://www.britishtelephones.com/rj45.htm) may answer your question.
-
The normal colours for pins 2 and 5 are white/blue and blue/white.
And strangely your answer also applies for "standard" RJ45 socket wiring too, for conductors 4 and 5 which are the ones the linked to documentation suggests are "normally" used for phone adapters! ;D
I'd still RTFM and test with a multimeter first though to be sure. :graduate:
-
Brilliant, that works . Thanks
-
......by the way, what does RTFM mean? If it's what i think it is and is a slightly rude direction to read the instructions to the adaptor then i have the following reply~:
I presume that this forum doesn't mind helping people who know less that them; my assumption, hence the full question i had was:
I do not know which colour is which numbered pin on a cat 5 cable. The patch panel only has a colour guide and presumed i might miss something working it out myself.
I do not know how the bt to rj-45 adaptor is wired, and there is no instructions, and I wasn't sure about breaking it open without breaking the plastic
In any case, I do not know which numbered pin in a BT socket goes to which pin in a flat rj-11 plug.
I do however, know how to wire a BT system and wondered with a quick question, what the convention for BT over cat-5 was as that was probably how the adaptor was wired...
As it is a simple question I thought that maybe someone would have a simple answer........which they did in the end.

Certainly not, it's what we're here for. But it's an open forum, and different people will respond in different ways. Please don't take offence; I'm sure it wasn't meant. :)

......by the way, what does RTFM mean?
It's a jocular abbrevbiation for "the information you seek is probably in the product documentation and not readily available to people trying to help you" so we hope you've looked there first. ;)

An abbreviated version of the builders' mantra...WAEFRTP ;D

And if you'd asked that up front the answers would have been much more appropriate. ;)
As it is respondents just have to guess what you do/don't know. :angel:
Personally I tend to err on the side of "they probably know a lot more than they are letting on" as:
1. More info can always be requested (or supplied)
2. Many people get insulted or feel patronised by detailed replies assuming they know nothing
3. Wasted effort (which is often not appreciated)
