Enterprise Services Application Module (ESAM) for the T-BERD/MTS-4000 Platform (Discontinued)

The industry’s broadest range of enterprise test capabilities in a single tester for IT organizations that maintain Ethernet/IP Local Area Networks (LANs).

Today’s IT networks are more complex than ever with Voice over IP, IP security cameras, presence, and remote applications being run over high-speed copper, fiber and wireless infrastructure. Complexity that was once confined to the data center is now finding its way closer and closer to the user causing the front-line IT technician to need to resolve a far greater range of faults than ever before. With even minor network faults having the potential to render employees unproductive, keeping the network up is now a mission-critical task. The ESAM addresses these challenges of modern networks with a modern approach.
