TRAI has released its regulations on quality of service standards for both wireline and cellular mobile services. For wireline services, TRAI has specified that billing complaints should be resolved within a maximum of four weeks. A parameter, answerto-seizure ratio, has been prescribed as an alternative to the call completion rate (CCR) wherever the CCR cannot be measured and reported. For cellular services, the benchmark for call drop rates has been revised from the existing less than 3 per cent to less than or equal to 2 per cent. The condition on accumulated downtime for community isolation has been replaced with a new parameter on network availability, wherein network availability will be assessed through two separate parameters –­ base transceiver stations' (BTSs) accumulated downtime and worst-affected BTSs due to downtime.
