TELMEX is widely considered one of the world's strongest carriers.  Its ability to provide a wide range of services and programs for Mexico's business and residential markets has distinguished the carrier from its peers around the globe.

As a strategic vendor to TELMEX, Mexico's leading telecommunications service provider, Ciena is providing the value of its FlexSelect™ architecture, which includes CoreStream Agility, for scalable capacity, design flexibility and network automation across the TELMEX network.

For several years, Ciena's CoreDirector® multiservice switch has been deployed in TELMEX's premier next-generation Mexico City network, one of the largest metropolitan area networks in the world. CoreDirector is also deployed in additional TELMEX metro networks as well as its long-distance network to enable a single, fully-automated nationwide infrastructure.
