If pppd is configured correctly, you must have a script in /etc/ppp/peers directory (his name depends on your config). To run pppd, just type:
pppd call script_name
If pppd is not configured correctly, important files are /etc/ppp/options, /etc/ppp/pap-secrets (or chap-secrets if your ISP use CHAP authentication) and of course /etc/ppp/peers/your_script_to_call_provider
