Having to use the excessively rigid, slow, static, boring expensive PSTN
to fix the cool, fast, flexible cheap, cool, fun Internet? That'll work
just fine, of course. Until, that is, one of the telcos in the path
saves a few bucks and routes a call leg over the Internet.
What will us network operators do when there is NO out of band
management path to anything? What will happen when you can't even place
a phone call?
The PSTN ran about 80 years or so on in-band signaling until a very
rational cost/benefit decision was made to remove signaling from the
traffic path. Physically seperating signaling (SS7) and routing (LERG,
etc) paths from the traffic (for all but the access link) was a large,
expensive, difficult effort, but worth it. The PSTN is full of
quasi-governmental central authorities for everything, and is all the
better for it.
