Re: BT cabling through patch panel



Great thread, whoever be warned.

In the UK we use 3 wire phones with 2 wires sent into the house. A
Master socket is the installed at the end of the incoming BT line.
This master socket has a Resistor abd cap, to provide the third wire
(this is used as the rininging signal). You are then when adding
extensions supposed to wire 3 wires to each Slave socket (no circuit).
You then have to be wary of the REN.

So if you just patch the incoming 2 wires to many Masters (buy usings
the Master RJ45 to BT) then you could end up sinking the line to your
house and then popping the card in the exchange.

So the best way is to make a lead from the master socket to the patch
panel (using 3 wires) then (as I have done on many occasions) create
a spider (that is a cable with many ends) this can then be used at
the patch panel to take the one line to many extension. This is a far
neater solution than doubling up on the patch panel, sods law will
dictate that you will need one of those points (unless you dedicated
a panel to phones out).

Then all you need do is plug Slave RJ45 to BT where each phone should
go. And of course turn the ringers off those phone that do not need
to sound to keep the REN to 4.

Hope this makes sense.
