How an operator upgraded its national legacy network to 400G infrastructure with the strategic support of Beyond Technology

Introducction

In the dynamic world of telecommunications , constant technological evolution is not optional—it's essential. A national operator in Mexico has remained at the forefront for over two decades thanks to a continuous network modernization strategy. From early E1 links to 400G infrastructure, this operator has relied on Beyond Technology as its strategic partner to design, implement, migrate, and maintain a resilient, scalable network aligned with the highest global standards. This long-term collaboration has been crucial in consolidating an architecture that supports operations for millions of residential and enterprise users across the country.

Success storyHow an operator upgraded its national legacy network to 400G infrastructure with the strategic support of Beyond Technology

Customer Overview

This is one of Mexico’s leading telecommunications operators, with nationwide coverage and services designed for both residential and corporate markets. Its network supports critical applications across sectors such as banking, retail, government, healthcare, and manufacturing, offering dedicated internet, private networks, high-capacity links, managed services, and multi-service connectivity.

More than 20 years ago, the company operated a modest infrastructure based on E1 and STM-1 links. Today, it runs one of the most advanced networks in the country, with national backbone transmission capabilities reaching 400G. This evolution has been made possible by a strategic approach and ongoing technical collaboration with Beyond Technology, who has supported the operator at every stage of its technological growth.

SOLUTION

Over the past two decades, Beyond Technology has played an active role in the operator’s technological transformation, executing numerous network evolution projects, including:

SOLUTION

Transitioning from legacy links to Carrier Ethernet, enabling 10G long-distance connections as a foundation for a modern IP/MPLS network.
Subsequent upgrades to 100G and 400G links, with technology updates to the national core and aggregation networks.
Progressive implementation of Juniper platforms, from legacy equipment like ERX-1440, M7i, M10i, M40e, M320, T1600, T4000, and TX Matrix Plus to advanced solutions such as MX480, MX960, PTX5000, MX2010, and more recently MX10008 and PTX10008.
Involvement in network design, installation, live migrations, and post-sales support, ensuring uninterrupted service during every technology transition.
Ongoing support for more than 170 core and aggregation routers and 380 switches, maintaining an incident rate below the industry average—validating the robustness of the Juniper solution.

Growth Plan

The operator plans to continue expanding its 400G infrastructure across new strategic routes and move toward even more automated and reliable architectures. Future phases will include the integration of real-time analytics, deep network visibility, and the deployment of AI-driven automation solutions to accelerate operations and proactively detect failures.

Project Impact

Thanks to a sustained technological evolution strategy and the ongoing partnership with Beyond Technology, this operator has radically transformed its network infrastructure—effectively responding to the explosive demand for connectivity in Mexico. The long-term collaboration has enabled not only the adoption of new technologies but also their seamless integration without compromising service stability. Today, the company is in a privileged position to drive Mexico’s digital development and continue delivering world-class services.
