The exchange will be used to deliver high speed ultra-flexible dedicated links for the Indian internet network. Earlier, VSNL had 396 mbps of internet connectivity, a majority of which was being delivered through 11 of its earth stations. These earth stations contribute 341 mbps, the FLAG optical fibre system provides 45 mbps and the remaining 10 mbps of bandwidth is sourced from SEA-ME-WE/FLAG to Singapore. Its total international bandwidth will now stand at 900 mbps. The exchange forms the prime hub between the 40 gigabit-per-second SEA-ME-WE3 optical fibre system and the Indian internet network. This network comprises over 200 internet service providers, 400 nodes and over 1000 corporate leased lines and the national internet backbone (NIB). The gigabit switching fabric will link Mumbai with high speed internet nodes located at Cochin, New Delhi, Chennai, Calcutta, Bangalore, Hyderabad and Pune. With the commissioning of the new switching fabric, VSNL will be able to offer high speed optical fibre connectivity worldwide. The telecom PSU also simultaneously announced the commissioning of 3STM-1 links, amounting to 455 megabits per second of SEA-ME-WE3 optical fibre capacity, to the Globe Centre in New York.

Satyam gateway Satyam Infoway Limited, the internet and e-commerce company today launched its international satellite gateway in Hyderabad. This is the company's third satellite gateway after Mumbai and Ahmedabad.

We have entered into tieups with SingTel, New Skies and Loral Cyberstar for these gateways,' said Rahul Swaroop, chief technology officer, Satyam Infoway.
