To be perfectly honest, I don’t expect those to ever convert. Sooner or later, their equipment will be replaced, and when it is, the person installing it will be faced with the question of what communication technology to use. I expect those choices to be what makes the step.

The comment about “and along with it, biSync and X.25” was not an idle one. We’re still waiting for the last bisync terminal to die, and X.25 has a constituency in the telephone world.

The other thing I notice, though, is that we don’t have people jumping through hoops to keep those things going. As long as they cause less trouble than they contribute value, value wins. The day the value gasps for breath, so will they.

I’m not even especially concerned about getting from step 4 to step 5. I suspect that economics will get applications to the native network; the only question is “when”. If A works better than B and is less cost to maintain, A will eventually win out.

My only real concern is getting from some variant of step 2b or 3 to 4. At least in part, my reason for describing “step 4” experiences is to point out that there are those who are going there, and to provide “no BS” analyses of that.
