AAC Service Data Module (SDM)
Supports ATM Managed Services
The Service Data Module for the AAC acts
as a Visual Networks
®
Analysis Service Element
(ASE). Specifi cally designed to support NxT1/E1 IMA
or DS3/E3 ATM networks, it monitors user-specifi ed
ATM ports and circuits, and communicates service
performance data and events to Visual UpTime
®
.
Kentrox and Visual Networks enable service
providers to introduce WAN Performance
Management Services based on industry-proven
hardware and software solutions. Service providers
can offer customers a variety of new managed
service options and a higher degree of fl exibility
for hybrid ATM/Frame Relay networks.
