The TruView™ and Visual Performance Manager™ CSU/DSU ASE is deployed on a T1 access line at the demarcation point between the provider network and customer premises. It supports full and fractional (FT1) T1 networks and provides connectivity through V.35 and additional digital cross-connect signal (DSX-1) interfaces to provide real-time and historical statistics to TruView and Visual Performance Manager.

Supports IP Transport and OmniPoint software for deployment in networks that use IP switching.

The ASE's drop-and-insert feature provides a secondary DSX-1 port that can connect to a private branch exchange at a customer's site. T1 timeslots can be segmented for a PBX on the same circuit carrying data traffic. (See Figure.)

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 TruView and Visual Performance Manager systems. ASEs offer in-depth, real-time, and historical visibility into the performance of an applications infrastructure. Data gathered by ASEs is stored in the VPM 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.

What is TruView and Visual Performance Manager?

TruView and Visual Performance Manager are flexible solutions that can scale to help the largest enterprises, carriers and managed service providers decrease the cost of performance management, increase revenue, and optimize utilization of existing assets. This is accomplished by enabling IT organizations to become a source of competitive advantage, not a cost center, by providing actionable visibility into a centralized integration point for managing applications, VoIP network and server performance across a complete network.
