Grade of service is the parameter of Switching system. A system can not be loaded according to its capacity so there are intentional blocking of certain numbers of call. Its shows how many calls from a system may fail if tried. Typically if GOS is 0.002 then out of 1000 calls 2 calls may fail or out of 500 call 1 call may fail.
