I don't remember Canadian POT phones (which are the same as USA phones, I believe) being different from Spanish phones. The system on UK was different, because they separated a ring wire - at least when I looked decades ago. There could be other subtle differences, specially regarding modems.
In the US, although there are typically four wires in the cable going to the house or business, POTS uses just two of wires (the red and the green), one of which is the "tip" and the other the "ring".
I think the issue between US and German phones (maybe others too) was the wiring in the RJ11 plug.
I had ISDN in my house for a while and even then only two wires were used...
The external wiring up to the terminator box is only 2 wires, but the S0 bus needs 4 wires. -- Per Jessen, Zürich (4.6°C) http://www.cloudsuisse.com/ - your owncloud, hosted in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
