as has been said, your switch will go into nights, make sure the nite prompts are going to handle call flow. i would do a prt 2250 in load 20 and disu both tn's, if you have power tn's built they are always disabled so no harm. you will get majot alarms but unless you have a remote monitor, no one will know if the switch is programed to handle nights..if the att unplugs at night then you have a good idea of how service will be affected
