I have decided to go with a DSL service as my main service and a dail-up ISP as my backup. (1) In order for this to work, I have to have both services, correct? Like DSL and AOL or something? (2) What hardware or software would accomodate automatic backup for the dial-up? Do I need one such as the Compex/Nextland or are there other options if not using 2 highspeed ISPs??
