Grade of Service is the percentage of calls that was not immediately served on the first attempt. The call can either be blocked or delayed as can be seen from Erlang B and Erlang C assumption. A GOS of 1% in Erlang B is 1 blocked in 100 attempts while in in Erlang C it is 1 call delayed for more than say 3 seconds out of 100 attempts.
