active500EM Access Controller

What is the active500EM

The AT&T activeARC? active500EM enables efficiency over Wired and Wi-Fi networks as IP traffic continues to grow. The system has 24 performance Gigabit ports for wired connection, as well as a built-in wireless controller to manage the AT&T activeARC? ARC1000MAP and ARC2000MAP access points. IT management can now balance their network performance from a unified platform designed with advanced features and greater control.
