India's 21.59 million-line telephone network is the largest in Asia, 3rd largest among emerging economies (after China and Republic of Korea) and the 12th largest in the world. India's telecom network comprises of 27,753 telephone exchanges, with a total equipped capacity of 272.17 Lakh lines and 226.3 Lakh working telephones. The Long Distance Transmission Network has nearly 1,70,000 route kilometers of terrestrial Microwave Radio Relay & Co-axial cables and about 171,000 route kilometers of Optical Fiber Cables. Fully automatic International Subscriber Dialing (ISD) service is available to almost all the countries. The total number of stations connected to National Subscriber Dialing (NSD) is over 18,000 and this is increasing fast. Yet the present tele-density is very low at about 2.2 per hundred persons, offering a vast scope for growth. In the field of International communications, tremendous progress was made by the use of Satellite Communication and submarine links.It is therefore not surprising that India has one of the fastest growing telecommunication systems in the world with system size (total connections) growing at an average of more than 20 percent over the last 4 years.
