Ericsson has won a deal to operate and maintain Vodafone India’s optical fibre cable network for three years.
The deal covers 10 geographical areas, known as circles, spanning 45,000km in East and West India.
Paolo Colella, Head of Region India at Ericsson, said: "Ericsson has been Vodafone's partner in the radio, core and transport domains for many years.
“This managed services agreement in India strengthens that partnership in a very important market and complements our collaborations in other parts of the world.”
The vendor saw revenues in India rise 74 percent in 2015.
It is the second deal that Ericsson has signed in the country this week.
It has also won a deal to supply Idea Cellular with a 4G/LTE network.
Meanwhile, the company unveiled a new revenue management tool.
Ericsson said it had worked with HP Enterprise on the cloud-based charging and billing solution, which is being trialed by Estonian operator Telia Eesti.
The operator's CTO, Tiit Tammiste, said Revenue Manager 16 “appears to offer a breakthrough approach”.
Ove Anebygd, Head of Solution Area OSS/BSS at Ericsson said: "Ericsson Revenue Manager is a game-changer that acts as a digital business enabler for service providers, reducing time-to-market from months to minutes and supporting any business model.
“It represents the realisation of Ericsson's vision of the true promise of Business Support Systems.
“Operators are making Ericsson Revenue Manager a key component of transformative IT programs while moving away from complex and costly BSS environments."
