Section 19 in Telecommunication Interconnection (Charges and Revenue Sharing) Regulation, 1999
19. The monthly rental of Rs. 600 specified for cellular mobile telecommunication services takes into account the use of ports in a mobile switching centre to provide connectivity with PSTN. The rental for cellular mobile is thus based on total capital cost incurred in providing the service, which includes the investment on ports. Further the air time charge of Rs. 6 per minute provides for the total operating and maintenance costs incurred on the asset, including the ports of a mobile switching centre. Thus charges for the port of a mobile switching centre used for providing connectivity to the PSTN need not be paid for, having already been taken into account in costing as explained earlier.
