Sounds like a digital- analog 480 port mix. Could have problems with the way he is booting the system- those drives are very sensitive! The fast busy is because the co trunks are not there yet, it's trying to grab them after dialing 3 digits (ars)but they are not available. Sounds like the analog bay (probably 4 or 5) is not booting up. Hopefully lec has insurance! PM me for any other ?.. time to move to an sx-200 icp. :toast:
