As I understand it, narrowband "basic service" 2B+D ISDN does
*not* require *any* new cabling.  Even if this is so, I have also
heard that not only are *new* installations using fiber, but also
that in some cases, perfectly serviceable in-place copper wiring
is being yanked and replaced by fiber, both to free up tight
cabling space *and* to capture the scrap value of the copper.

Such a trend would accelerate the move away from the bandwidth
restrictions imposed by copper, facilitating the growth of a base
of potential customers for broadband ISDN, customers that would
not need further investment in new cabling.

Is this an (at least superficially) correct understanding of the
economics involved ?
