Description |
Units |
Limits |
The ratio of calls offered to a trunk group that can be blocked |
(Unitless) |
Between 0.001 and 0.500 |
|

Example
To estimate how much traffic a trunk group of 200 lines can carry at 0.030 (3%) blocking, assuming that 70% of blocked calls are immediately retried, enter
=ExtErlBTraffic(0.030,200,70)
