EdenTree Deploys Connect_ET System In Spirent Communications Sales Demo Laboratory

EdenTree Technologies announces that Spirent Communications™ (NYSE: SPM; LSE: SPT) has deployed its Connect_ET system to enhance Spirent’s advanced sales demonstration capabilities. Connect_ET is a client/server software application that controls an automated cable switcher, allowing test lab resources to be managed, accessed, switched, reserved and controlled remotely. As deployed in Spirent’s Sales Demonstration Lab, the Connect_ET system assists sales personnel to set up and execute remote product demonstrations.

“Spirent Communications’ Remote Sales Demonstration Laboratory is an important resource, enabling our sales organization, partners and distributors to quickly deliver training and demonstrations in a live test environment,” said Jim R. Smith, director of Sales Support for Spirent Communications. “The Sales Lab is unique in the industry and offers remote access to a wide array of customers. The Connect_ET system enhances our lab by minimizing the complexity and time required to set up and execute remote sales demonstrations.”

The Connect_ET client application allows various demonstration configurations to be created, stored, recalled and automatically interconnected. This provides Spirent’s sales force with flexible remote demonstration capabilities, minimizing the need for human intervention in the lab itself. Connect_ET also helps streamline the management of a wide variety of test equipment providing resource management features, including equipment sharing, scheduling, and reservations and reporting.

“Spirent’s Sales Lab presents a great opportunity for EdenTree to contribute to a powerful solution for Spirent’s sales force and customers,” said Roberta Gonzalez, EdenTree’s vice president of Marketing and Business Development. “Spirent and EdenTree anticipate additional applications for Connect_ET within Spirent’s Sales Lab for internal personnel, partners, and customers worldwide.”
