ign companies viz. Alcatel, Siemens, Fujitsu, AT&T, GPT, Ericsson and NEC have been validated and approved by DOT for introduction in Indian Network. In addition, the technology developed by C-DOT has also been validated. Manufacturing facilities, based on these technologies except GPT, have been set up and a capacity of about 4.0 million lines now exists in the country. With the increased investments in the Value Added Services sector, the demand for switching products such as Cellular switches, ISDN switches, gateway switches, ATM etc. is bound to grow sharply. The passenger traffic at all airports in India is likely to almost double, according to the planning commission, from 23.40 million in 1996-97 to 40.55 million in 2001-02. Domestic passenger traffic is expected to touch 52.3 million; international traffic around 32.4 million and cargo about one million tons.

The existing aviation infrastructure can support a 20 per cent rise in passenger traffic and a 10 per cent growth in cargo. This effectively means a saturation of Indian airports over the next few years.

Over the last 10 years, the government has invested more than US $ 315 million in the modernization of five international airports. The modernization measures include improvement in navigational equipment, upgradation of terminals and passenger support facilities.
