Imran - 23rd September 2005  (14:52 GMT)

I want to know different strategies that need to bbe adopted to improve ASR in EWSD exchabges.
I am working at OMC and EWSD transits are connected to different exchanges like E10-B ,Huawei ,ZTE ,Ericson
I want to know how can I improve ASR in different direction.What should I look at .

Riyadh - 1st November 2004  (09:35 GMT)

can i use the following formula to calculate ASR ?

ASR = Successful Calls / No. of bids. *100

And, what are the possible reasons for lower or drop in ASR.

And, what are the factors that can affect the ASR?

Dear Naveed,

The ITU earlier known as (CCITT) documents are available here. The E600 is at

http://www.mit.edu/afs/net.mit.edu/reference/ccitt/1992/e/e600.doc

If u are working with AX-10 Ericsson switch, the command and the counter which are used for calculating these parameters will be of much help

Dear Mahalingam
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
