    Get a crapload of wire and start winding. Or go to a shop and buy it.

    Probably easier to buy.

    But consider:-
    How much current will it have to carry?
    What frequency will it work at?
    Does the DC resistance matter?
    For iron or ferrite cores - what happens if it magnetically saturates?

    Its current is the phone line current and I don't think it is over than a few mA
    I want to use it for an ADSL line so I think that frequency is in the mega Hertz range
    surely regards to its high frequency the core of the coil will be from ferrite.

    :eek: Go easy here............hooking random stuff across phone lines, can open a gigantic can of worms for you -- Phone companies don't like random add-ons.

    you need supply more necessary informations, e.g. how many DC current will coils pass, what application are two coils? work frequency? dimension?
