To ensure seamless inter-connection, TRAI monitors the level of congestion at the POIs among various service providers on a monthly basis.This parameter signifies the ease with which a customer of one network is able to communicate with a customer of another network. It also reflects as to how effective is the inter-connection between two networks.The benchmark notified by TRAI for this parameter is less than 0.5 per cent. This means that out of 200 calls between two operators, only one call should face a congestion problem.During the period, the Cellular Mobile Telephone Subscriber base has increased from 315.31 million in September 2008 to 346.89 million in December 2008, while the number of POIs with congestion has decreased from 129 in September 2008 to 66 in December 2008
