The Internet Protocol (IP)-based technology NGN would provide additional facilities to customers on their landline. The new technology would improve the telecommunication network in Northeast India, BSNL's north-eastern circle chief general manager (CGM) D.P. Singh told reporters in Agartala on Tuesday.
Meghalaya Chief Minister Mukul Sangma launched the new NGN service in Shillong on Saturday, and in Tripura, the state's Information Technology, Industries and Commerce minister Tapan Chakraborty commissioned the technology in Agartala on Monday night.
Singh said that the NGN would gradually be launched in all the eight north-eastern states.
He said the NGN is aimed at increasing the landline usages at a time when everyone is using mobile connectivity for communication.
There would be no change in the telephone numbers and billing cycle and the rate for calls would also be the same except when using other facilities such as video, picture and data through session initiation protocol, the CGM said.
The NGN would improve voice quality and offer broadband services, video calling, nationwide Centrex, seven party conferencing facilities besides increasing the reach, coverage and availability of BSNL's broadband services.
With its multimedia services, the new system allows at least 30 subscribers to interact with one another by video calling, graphics, picture, data, and also by multiple video conferencing through Session Initiation Protocol telephone handsets, the official added.
