you didn't miss anything. dtmf gave you the programming for the older 308 (tan) front, I think yours has a black front case on it, which is an "NO 308" which will program like openwire said ITCM*#746* and follow the 1024 manual you have. A fast busy means an error, make sure the handsets in it's cradle and your at station 10. (to find station 10 go to a phone and dial 0, where it goes, is station 10) try to use a phone that's in a back room somewhere because if ya try the test above from station 10 you'll be trying to call yourself. Hope that wasn't confusing.
