Lucky us in this city are slated to get ISDN in two years.

I believe it requires two twisted pairs to each phone within the
house.  I wonder whether my current house wiring of standard four
conductor cable to each modular phone jack will be adequate, or will
the wires have to be replaced with special controlled impedence wiring
when I order ISDN? I think the short length of straight non-twisted
wire from the lightning protector to the phone jack is short enough to
allow reflections to be kept to a minimum, hence allowing the digital
signal to be received and transmitted properly.
