voice codec = 8 kbps = 8000 bps
TTI per frame = 20 msec = 0.02 sec
duration of busy hour = 1 hour = 3600 sec

1. Based on Table Erlang B, Voice path options for 1 Erl with blocking 0.01%, N = 7 path options

2. Data erlang =
(total number of frames transmitted * TTI per frame)/Duration of busy hour

1 Erl = (x * 0.02)/3600
x = total number of frames transmitted = 3600/0.02 = 180,000 frames

y = total number of kbps transmitted = 180,000 * 8 kbps = 1440 Mbps
