Hello Jan,

What does ATA mean ?

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..

simple, isn’t it.
