pppd dialin host how-to?

Possibly an obvious question, but most of what I can find on google doesn't help. Does anyone know of a decent how-to on setting up a dialin server (preferably with the calling side authentication config too).? I have to be set up for a cellular modem in about 36 hours and I haven't used dialup equipment under linux before. Dos & Win yes - I'm not hopeless - but I got into linux after I got broadband.
