I observe a lot of users expecting to use ISDN connections as if they were a
dedicated line. "ISDN is cheaper than Frame Relay". I have noted that some
ISDN tariffs call out higher prices for "data" use of a B channel than analog
use. It seems that the phone companies are trying to take advantage of new
environments to increase income.
On the other hand, it costs a bit more to install ISDN than more analog
circuits. I also suspect that long holding times take up ISDN switch
capacity. I wonder if telephone engineering is keeping up with the usage
changes.
