Bharti Airtel uses Epsilon’s First Line Maintenance services to efficiently support it’s global network through the use of professional and dedicated engineers.

Bharti Airtel has nearly 313 million customers across its operations in 20 countries in Asia and Africa. Its global network spans five continents with more than 400 interconnect partners.

In order to maintain its global presence, it uses Epsilon’s First Line Maintenance solution to ensure maximum uptime and network availability in key global communications hubs. Where it needs expert support, it has outsourced network maintenance to Epsilon and relies on it to keep critical interconnection points in London and Paris up and running and operating efficiently.

It trusts Epsilon because of the reliability of its engineers and it’s more than a decade of experience in network outsourcing and serving the international needs of service providers. First Line Maintenance services from Epsilon enable global operators to fill resource gaps efficiently with an outsourced solution from a trusted provider.



Global network operators are challenged to have experts on the ground in communications hubs around the world. They cannot afford for their network traffic to be disrupted but must find an efficient way to maintain their global infrastructure. For Bharti Airtel, the challenge was to find a solution that could cost-effectively serve their needs outside of their home markets in Asia and Africa. Global connectivity is key to its business but the majority of their staff are located in markets where they also have domestic operations.

It needed a solution that could fill resource gaps in critical interconnection points without needing to invest budget in full-time staff on the ground. In addition, it needed to use the available resource flexibly and address issues as they pop up. This mix of requirements meant it needed a partner with a unique understanding of outsourcing and the ability to deliver.


Since 2010, Bharti Airtel has outsourced First Line Maintenance to Epsilon in Telehouse East, London, and Telehouse 2 in Paris. Epsilon has delivered a service package tailored to the specific needs of Bharti Airtel with the flexibility to scale it up or down with Bharti Airtel’s requirements. Every month, it has access to hours of expert support in these locations with the option to expand this as its needs grow.

Epsilon’s First Line Maintenance portfolio includes on-site maintenance, network monitoring, spare parts handling, and system integration services. Its expert engineers are able to function as an extension of Bharti Airtel’s team and provide a seamless and integrated service. With Epsilon’s support, Bharti Airtel has a reliable presence on the ground that is able to support its networking needs.

As part of Epsilon’s typical First Line Maintenance programme, it performed a site survey with the client to establish the status quo of the facility and get the team familiar with the operations at the site. Epsilon staff was then added to the permanent access list to allow immediate access to the site whenever required.

By outsourcing First Line Maintenance to Epsilon, Bharti Airtel is able to support its infrastructure in more places with a reliable and experienced outsourcing partner.

Our aim is to support Bharti Airtel with the most skilled engineers available and give them complete confidence in our ability to maintain its infrastructure. First Line Maintenance is an extremely valuable and effective way to add new skills and resource to your operation without adding the cost and complexity of training and developing in-house staff. We’re proud to be a part of Bharti Airtel’s global success.
