A subscriber makes three phone calls of 3 minutes, 4 minutes and 2 minutes duration in a one hour period. Calculate the subscriber traffic in erlangs, CCS and CM.
Subscriber traffic in erlangs = (busy period)/( total period) = (3 +4+2)/60 = 0.15 E
Traffic in CCS = ((3 +4+2) x 60)/100 = 540/100 = 5.4 CCS
Traffic in CM = 3 + 4 + 2 = 9 CM.
