Buenos Aires, Argentina, July NETWORK OPERABILITY INDICATORS INDICADORES Service accessibility indicator This indicator is obtained from the resource allocation rate (RAR), which is defined as the percentage ratio of successful allocations of resources required for a given call to the total number of attempted allocations. Measurements need to be taken on a daily basis and at the time of peak traffic. The indicator is obtained from the monthly sum of daily values using the following formula: MOBILE ACCESS NETWORKSFIXED ACCESS NETWORKS where: N:Number of days in the month C AED :Number of daily successful resource allocations C AD :Number of daily resource allocation attempts RAR:Resource allocation rate

Buenos Aires, Argentina, July NETWORK OPERABILITY INDICATORS INDICADORES Service retainability (SR) indicator This indicator is obtained from the cut-off rate (CR), defined as the number of established calls that are released for a reason other than intentional by any of the parties involved in the call as a percentage of the total quantity of resources allocated for traffic management purposes. This is measured daily at the time of peak traffic. The indicator is obtained from the monthly sum of daily values using the following formula : MOBILE ACCESS NETWORKSFIXED ACCESS NETWORKS where: N:Number of days in the month C DRLI :Daily number of resources released involuntarily C DRA :Daily number of assigned resources CR:Cut-off rate

Buenos Aires, Argentina, July NETWORK OPERABILITY INDICATORS INDICADORES Short-message delivery rate (SMDR) The short message delivery rate is the percentage ratio of the quantity of short messages actually delivered by the short message service centre to the total quantity of short messages received by the centre. The indicator is obtained from the monthly sum of daily values using the following formula: where: N:Number of days in the month CD SMSE :Daily number of SMSs delivered CD SMSR :Daily number of SMSs received by the SMSC SMDR:Short message delivery rate
