the call. And the reconfiguration? Essentially grabbing

I would argue that the routing was (at that time) essentially static. As I
understand it CO's were not able to dynamically reroute calls if a trunk
failed - that had to be configured in as an alternate path.
The catanet model would allow 75% of the network to go away and it would
dynamically learn a new way to route to the destination; and the fact
that it was packet based and not circuit swithed would mean that it was
self healing. Not possible with circuit switches; you have to hang up
and redial and hope that an alternate path had been configured in.
