0.17 erlang ? It all depends on your observation period. Do you compute your ACA per hour, or per day, per week ?
If it is per hour (for instance, at busy hour), the observation period is 1 hour.
ATA = 0.17 means a usage of one channel during 0.17 hour, which means 612 seconds.
For instance, one TCH allocated during 612 seconds, or 2 TCH allocated during 200 seconds for the first one, and 412 seconds for the second one..
Sorry for confusion – ATA = AVERAGE TIME TO ANSWER. The report is covering a period of one week and shows average time to answer as .17 mins. I know this isn’t 17 seconds [as in hh:mm:ss] and just wanted to know how I converted it to ss.
Sorry for my obvious ignorance. Does this change your replies?
is thie a call connect time.
as you said ATA = AVERAGE TIME TO ANSWER means from the time call origenated till call answered.If this is so then cant count it in earlang.as erlang in is short Hour per hour traffic mean traffic ch occupied then only.as told by steave.
