Please tell me what load I need to go to to see how many loop (LPK) keys I have on my consoles. are loop keys similar to rollovers? So that if I have five loop keys my console can have 5 simultaneous calls? and will the 6th caller wait in queue? and how can I tell how long they'll wait? Will they queue until answered or is there some kind of timer? I need a crash course in Console 101 and appreciate all the help you can give me. Option 61C 25.40. thanks!
