Diff bet CallCompletionRate(CCR),CallSuccessRate(CSR)&CallSetupSuccessRate(CSSR)

Can any body tell me the difference between Call Completion Rate (CCR),Call Success Rate (CSR) & Call Setup Success Rate (CSSR)? I am getting the formula as CCR=call completed/call attempts, CSR=call successful/call attempt, ASR=call answered / called siezers and CSSR = call set up successful/call attempt.'

My doubt is what is the diff betn call set up, call success and call completed?

hi
as we know : DCR=drop call rate
so : CSR=CSSR(1-DCR) 
csr= reffers to the test equipments ability to setup and hold a call for 2 minutes  but ccr= reffers to completed call
