Seeing as Andrews and Arnold's (AAISP) offer dual line / bonded ADSL, I'm intending to get a second line, and tie the two together for performance (as opposed to failover). Apparently AAISP do this by IP routing alone not by PPP multilink as in the bad old days of dial-up.
The plan is to get a Juniper SSG20 up and running, with two ADSL modem modules slotted into it. I'd appreciate a hand if anyone around is a guru with Juniper / ScreenOS.
