I have been asked by my VP to let her know what is the normal and what is abnormal CCS for trunk groups. As much as I can find on my own is only what the definition of "CCS" (Centrum Call Seconds) is. I know its a unit of measurement for trunk usage in seconds but I don't know what would be a normal amount or what is an alarming number that I need to make myself aware of in order to look out for it. Does anyone have any guesses or know already what "normal or abnormal" would equal? Thank you for any help that you may offer.
