The C-DOT exchange at Kittur will be upgraded to MAX-NG to offer NGN (Next Generation Networks) services. NGN refers to an all Internet Protocol (IP) network which gives great operational advantages to the operators and subscribers alike. The up-gradation program will bring VoIP and other broadband services to the aging fixed line infrastructure, comprising of its MAX / RAX switches. C-DOT has also developed NGN, GPON which will build broadband pipes to homes, SOHO's and multi-dwelling units. C-DOT in all these years has been on the technology forefront and significantly contributed to the Indian telecom network digitization, bridging the digital divide between the rural and urban, establishing strong telecom manufacturing infrastructure and employment generations. For the next two-to-three years, C-DOT is focusing on design and developing systems which are of strategic importance to the country.
Often, the real import of an event is realised long after its occurrence, when we have the benefit of hindsight. This is what happened in case of RAX, the first product developed by C-DOT, to go into India’s telecom network at the historic city of Kittur, Karnataka, on 21st July 1986. RAX appeared on the scene at a time when country’s telecom network was way under-developed, to say the least. The tele-density languished at one, that is, one telephone for one hundred inhabitants & rural tele-density was zero for all practical purposes.
The greatest advantage of RAX was that it was designed for Indian conditions of high ambient temperatures, dust and unreliable power. It required no air-conditioning. It was based on contemporary digital switching technology with microprocessor based controllers and had no moving parts, which gave it immunity against dust, the bane of electromechanical Strowger and Crossbar exchanges in India. Named 128 P RAX, it was a tiny 128 ports switch. It had only analog trunks to connect it to a larger exchange in a nearby city. It could cater to a total of 80 subscribers and had 24 analog trunks to connect to the city exchange. But in villages with practically no telephones, 80 was a big number. There must be a large number of villagers who made or received their first ever call through C-DOT RAX.
128 P RAX was successful beyond all expectations. It acquired a legendary status in no time at all. It extended connectivity, including STD, ISD to rural areas. 26 manufacturers went into RAX production. RAX-a-day programme was started by DoT which grew to something like 32 RAXes a day. By March 1993, more than 10000 RAXes had been produced. Other developing countries evinced great interest in RAX and exports to Vietnam, Nepal and Bangladesh followed.
