RJ11 - buy straight or reverse?

I've spent more than an hour now reading the old threads about connecting to the RJ11 connector on the boards - I have 7 controllers where one of the RJ45 connectors came loose.

I understand from the documentation that the RJ11 is "in" only, but most of the references are also mentioning this is because of reversed (? right term) nature of the phone cable.

When I went to monoprice (http://www.monoprice.com/products/subdepartment.asp?c_id=102&cp_id=10222#1022203) I see they have reverse RJ11 (for voice) and straight (for data). I would have assumed I should just buy the data cable but am confused by the references I've read on the old forum posts to the reversed nature of the cable.

What should I buy?

Thanks!!

Voice cable. Reverse pinout..

In/out not really the issue.. When using RJ-11 cable between two controllers, one end must go to the RJ-11 jack, and the other end must go to one of the RJ-45.. That is the real restriction.

cool thanks - I'll buy reversed. I guess part of me was hoping (since I have no engineering in my brain at all) that the data cable would allow me to connect RJ11 to RJ11 between two controllers, instead of RJ45(out)-->RJ11(in).
Thanks again!

Well, technically, it would, but, the trick is keeping track of that oddball straight through RJ11 cable. You get it mixed up with the other type, and you are crossing your ground and +10V supplies, which can't be good for anything...
