BSNL to upgrade to NGN technology to keep up with the evolving internet
BSNL currently uses Time Division Multiplexing (TDM) technology, which only offers voice facility for landline subscribers. Once upgraded to NGN (internet-protocol-based technology), TDM will support video, data service and better telecommunication and broadband networks.
NGN will provide improved voice quality, offer broadband services, video calling and seven-party conferencing facilities, nationwide Centrex, and also increase the reach, coverage and availability of BSNL’s broadband services. Billing rates will remain the same, but value added services such as video calling will be billed separately.
“At present, BSNL plans to convert 14 million telephone lines with NGN technology. This is expected to cover more than 80 percent urban customers and approximately 90 percent rural customers,” said BSNL in a statement.
“However, it is expected that entire fixed line customers will have NGN facility by December, 2017. Initially, BSNL plans to invest approximately Rs 1,000 crore in upgrading the TDM technology with NGN technology,” it added.
