The Visual UpTime® Select™ DS3/E3* LinkSafe™ inline probe ASE complies with Class A standards for countries using DS3 access lines and supports digital transmission at the DS3 rate of 45 Mbps. This ASE supports IP Transport software for deployment in ATMbased data networks that use IP switching over DS3 physical lines.

The DS3/E3 ASE includes LinkSafe technology to protect circuit integrity in case of an ASE outage, as well as power failure notification. This ASE is designed for deployment at the network demarcation point between a subscriber’s CPE and the WAN. The figure below shows the ASE positioned between a Line Services Unit and a customer edge router on a DS3 line.

What are ASEs?

ASEs (Analysis Service Elements) are data collection and network performance monitoring hardware devices placed on a wide area network (WAN) or Local Area Network (LAN) as part of the Visual Performance Management system, which offers in-depth, real-time, and historical visibility into the performance of your applications infrastructure. Data gathered by ASEs is stored in the Visual Performance Manager server and displayed and analyzed from the Web portal interface. As a service level management tool, ASEs indicate when services are being met, provide warnings when services start to degrade, and send alerts when services are not met.
