I worked at a site today, that was programmed by me from the sheet from the engineer. they wanted to make a program change to main star application. per the engineer the star looks at the star programming for each call that comes into the application. but that the time and application order has to be in the correct order. or the call my go to the wrong route. to change how the star is programmed wasn't a big deal. but i would like to know more on the star programming.

Could someone give a 101 class on it please,

thanks
