Dial on demand using ISDN should not take as long as 10 seconds. It
should be able to do it in 2 or 3. The ISDN call should connect in
less than 1s and PPP negotiatiation shouldn't take much longer than 2
seconds (unless the 2 endpoints are trying to negotiate different
parameters and thus having to go through multiple configuration cycles
until they come to an agreement - in which case you should set your
initial values so that such re-negotiation does not happen.)

On the other hand, from the teleco's point of view, multiple,
frequent, short connections are not a good scenario. Setting up a call
uses much more exchange  resources than keeping a call active (which
just ties up trunks and uses almost no processing power). So the
telecos probably would not like the connect for 5s, idle for 15s,
connect for 30s, idle for 2 mins, connect for 1 minute .... etc usage
pattern.
