- In the PSTN? Wrong. New equipment is brought in because it is cheaper
- to operate or corrects deficiencies in the existing network. Why do
- you suppose the BOCs were retiring '50s era crossbar technology and leaving
- older '20s era stepper switches? Because the crossbars were too expensive to
- maintain. Very few countries in the world invest bucks in their telephone
- infrastructure just for the sizzle of newer, faster technology. Japan is a
- notable exception, with the government committed to promoting the establishment
- of ISDN regardless of whether it's proven to be cost effective. The jury
- is still out on whether this proactive approach is really more farsighted than
- the cost-justified approach being used in most of the rest of the world.

- A retail business is not comparable to a regulated telephone utility.
- Market forces operate in different ways. A retail business strives to
- create a demand for a product or service. A utility, on the other hand,
- want to exactly match supply to the predicted demand. If demand is
- stronger than expected, the utility will be unable to react quickly and
- frustrated subscribers will complain to the PUC. If demand is weaker
- than expected, the utility's ongoing capital expenses will not be
- offset by increased revenue and may force it to apply for a rate increase.
- For these reasons, utilities generally want to *avoid* creating a greater
- demand for a service than anticipated.
-
- It is significant to note that ISDN was initially conceived while AT&T
- was still a monopoly and owned all the embedded CPE. The implicit assumption
- (for BRI anyway) is that the service will be available end-to-end, a valid
- assumption in those days when everything from end-to-end was under their
- control. I'm not sure what would have happened had the divestiture never
- occured; the predivestiture phone network is/was littered with occasional
- examples of oddball technologies that were supposed to be the wave of the
- future but never quite caught on, because in the end they couldn't be
- cost-justified.
