32. M/s Bharti Airtel and M/s TCL have said that the conversion factor should be 4. To support this, M/s TCL has also submitted that there is no benefit of economies of scale in the cost of higher capacity interfaces. M/s Bharti Airtel has given some examples of under-recovery and excess recovery by changing the interface mix. Similar example has also been cited by M/s TCL stating that full recovery of cost is possible only when the capacity sold is exactly as per the volume and interface mix assumed by TRAI.
