Wiring? (1 Viewer)

I realise this isn't really a 1010011010 type problem but thought someone here may have some answers.

I want to connect a a modern (RJ45) phone plug to a rotary/dial phone cable. Is this possible and if so, how do I go about it?

I've seen a few things online that are kind of pointing me in the right direction but thought one of you may have done something like this and pass on some tips!

An RJ11 connector (regular phone connection) will plug into a RJ45 socket but not the opposite way around (as an RJ45 is too big for an RJ11 socket). What is it you want to do? Use a rotary/dial phone over VOIP? If so, an ATA adaptor is what you'll need. e.g. http://www.blueface.ie/shop/shop.aspx?products=hardware

I just want to plug the old phone into the wall! So I was wondering if it's possible to attach the RJ11 (not RJ45 thanks!) to the old cable?

I was hoping there would a straightforward way of wiring a modern plug to the old telephone cord.

Hmm, I'm guessing phones from the 80's still used the RJ11 cable spec - on the end of the old telephone cord, it has 4 wires on it? (looking at http://en.wikipedia.org/wiki/RJ11,_RJ14,_RJ25#RJ11.2C_RJ14.2C_RJ25_wiring_details) If so, it should just be a matter of getting a rj11 plastic connector and a crimping tool. If you know any IT/Phone engineers you should be sorted for those, otherwise maplin is your man.

Yeah it has the black, yellow,green and red wires alright! Crimping tool is probably the way to go then! Thanks for the info
