Let me take another stab at describing it and maybe it'll help.

The modem dials out to the Cisco modem bank, the modem bank (i am  
guessing here, as i am not this far) is configured to authenticate  
against Radius. Radius is configured to talk to Mysql and uses a  
query that checks the username/password, based on the exit status it  
accepts or denies the connection request to the modem.

As i said my PPP knowledge is weak, but isn't what i described part  
of the PAP/CHAP handshake process that Radius is configured to use?  
Please correct me if i am mistaken.

Thanks,
