Perhaps a question for our Southern Ireland members -
Can someone please confirm the telephone wiring connections used by
Eircom? BT use 2 wires (typically Blue and White/Blue) to supply -50V to
a master socket which supplies all the secondary sockets with -50V
between pins 2 & 5 and pin 3 being used for the ringer. But IIRC
Southern Irish telephones use RJ11 plugs and only the 2 centre pins.
What is the equivalent to BT's master socket?
Is the line voltage the same as BT, i.e. -50V dc?
If a RJ45 socket is used for RJ11 plug, is pin 4 (blue) the positive?
With no ringer signal, do the phones contain the circuitry?
TIA
Steve
