ANNEX I TARGETS AND KPIS 1. QUALITY OF SERVICE PARAMETERS FOR FIXED LINE SERVICES Every Fixed Line Telecommunications Operator shall meet the following Quality of Service standards set for Fixed Line Services in respect of each specified parameter measured by test traffic in any locality and shall submit a report in the reporting period based on daily peak hour conditions. Table 1: Quality of Service parameters for Fixed line Services (Technical) Parameter Definition Formula Target Urban Rural Unsuccessful call ratio (USCR) The ratio of unsuccessful calls to the total number of call attempts in a specified time period. (Number of Unsuccessful call attempts/ total number of call attempts) X100% ≤ 2% ≤ 5% Network Availability The degree to which the network is operable and not in the state of failure or outage at any point in time. It measures the total uptime of the network. Network Availability = (Total operational minutesTotal minutes of service downtime) / Total operational minutes) X100% > 95% > 90% Call Set-up Time The period starting when the address information required for setting up a call is received by the network and finishing when the called party busy tone or ringing tone or answer signal or alerting message is received by the calling party. Time of Call Alerting - Time of receiving Dial tone ≤ 5 Sec (all national calls) ≤ 8 Sec (all national calls) Call Drop Rate The percentage of successfully established voice calls that are dropped by the network before they can be ended normally by the user. Call Drop Rate = (Number of calls terminated unwillingly/ Total number of successfully established calls)X100% ≤ 2% ≤ 4% Call Drop Rate is the probability of a call terminating without the user causing it. 10
