Yep, that's also the case in western Europa. AFAIK, nobody uses twisted pair for analog telephone wiring. For ISDN, it is often used on the S0 bus, but that's more for convenience.
That is similar to what, in Canada, is referred to as "drop wire". It would be used to run from the cable in the street to the home. Inside the home, a cable with 4 wires, often called "quad" or "JKT" was run around the home. More recently, 3 pair CAT 3 cable has been used inside for running phone lines. The cables back to the central office have been twisted pairs for many, many years, although not necessarily even CAT 3 quality. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
