Default Can an old (1962) telephone be connected to a modern BT socket?

Hello.
as header really.
Phone is an old bakelite gadget with 3 wires that would have been hardwired
into a junction box.
Can this be connected to a more modern plug in BT socket and if so ~ how?

Many thanks
Nick.


Of course it can.


The whole exchange kit is backwards compatible to the year dot, except
pre loop disconnect dial stuff won't off-hook get you an operator to ask
to connect you...But you can dial by tapping the off-hook switch..;-)

I cannot remember which wires go where though: there will be two signal
and one bell wire..so if you can identify which plug wires to connect to
in the first place..two will have about 50V DC across them, so that's
one way to find them....the bell wire will give you a nasty tingle when
someone rings you, so conncect theh hamster across various pairs and
dial in from yer mobile. When he leaps, that's teh bell wire..
there are only a finite number of combinations to try, and you won't
screw the exchange up. Not sure about the hamster tho..

Try em till it works..
