Is this really SO difficult to understand !?!
If you don't realise that internet communication via dialup
[and also not via dialup] entails a series of traffic flows,
consider the following analogy.

You plan to make a pysical journey thus:
1. collect your documents.
2. lock the house.
3. walk to the bus stop.
4. board the bus
5. walk from the bus to your destination.

If there's a bus 'strike' causing busses to be much
delayed, and you KNOW of such then you can make an
intelligent decision to re-schedule your journey to another
day/time.

Similarly the ISP's system knows that congestion is
causing an extra wait  before the client is PAP-confirmed.
And by feeding back a telco engaged signal to before
receiving modem will save their client the futile telco
connect cost.

Similarly if you KNOW that there will be a long
queue/wait at a facility, you can intelligently decide to
NOT start your 'journey' and rather 'try another time'.  
But NOT if the 'signal' is not fed back from the
over-loaded facility to the client.

 
 
 

1. Can ISP detect when dial-ins are 'overloaded' ?

Surely ISP's can detect when the 'queue of dial-ins has
increased so that the wait until next-stage will be excessive' ?

My ppp-script is set to [say] 99 secsonds to exit if PAP hasn't
confirmed.  This means that when the ISP's load is high, I don't
get an engaged signal, but rather I get the cost of a dud-call
and an exit after the PAP timeout causes an exit.

WTF don't the ISP[s] just send an engaged signal to their
input-modem/s. To save their clients unnecesaary costs ?
