(Redirected from Solution)
Table 1 below shows the results for Erlang B and Engset calculations.
| Number of sourses | 10 | 20 | 100 |
| traffic offered in Erlang | 5 | 5 | 5 |
| GoS | 0.01 | 0.01 | 0.01 |
| # of lines (Engset) | 9 | 10 | 11 |
| # of lines (Erlang) | 11 | 11 | 11 |
Table 1: - TABLE COMPARING RESULTS FOR ERLANG AND ENGSET CALCULATIONS FOR NUMBER OF LINES SPECIFIED FOR SAME NUMBER OF SOURCES AND OFFERED TRAFFIC AT 0.01 GoS.
Notice that the Erlang B formula specifies the maximum number of lines needed even if there are fewer sources.
