How do we calclulate the following
for 5ESS Local Switch from Lucent and AXE-10 from Ericsson with reference to the ITU document
ITU-T 600. What are the counters that should be taken to calculate offered by these switches.
ITU-T Recommendation E.600
2.13 Completion ratio
2.14 Answer Seizure Ration(ASR)
2.15 Answer bid ratio (ABR)4th January 2003 at 09:43 #34982Naveed ShaikhGuest
1. the formula for calculating Call Completion Ratio is
CCR= (CCS with answer(Out) + CCS Subs Busy+
CCS Unanswered)/ Out going Call Seizure
2.ASR(O.G)= CCS with Answer/Out
going Call Seizure
ASR(I.C)=CCS with Answer/Calls Carreied I.C
i DONT KNOW THAT THESE FORMULAS ARE according to ITU documents or not but these formulas are being applied by the Big Telecom operator in pakistan for EWSD and Ax-10(ericsson) switches.
I would like to know about ABR.
I will be thankful if you can send me The ITU recomendation docs
