SmartWORKS DP
The SmartWORKS DP sets the standard for passive tapping of T1/E1 trunks in high-density environments. The SmartWORKS DP is a reliable tool used globally by many of the world’s largest call logging application providers.
High Density Passive Tap Capabilities
Operating between a central office and PBX, the SmartWORKS DP’s high impedance receivers records both sides of a call without interrupting service. Each blade can process up to 60 channels, with a maximum of 512 channels per host. Service is never interrupted even if the SmartWORKS DP-equipped PC is shut down.
International Protocol Support
The SmartWORKS DP supports Channel Associated Signaling (CAS), Non-Facility Associated Signaling (NFAS) , DASS2 and any Q.931 based ISDN variant. Trunk coding and framing is selected on a per framer basis. This allows a single blade to monitor two trunks, each with different settings.
Built in Performance Monitoring
Network conditions and call statistics are easily accessed via the SmartWORKS API. Event driven alarms are reported for loss of signal conditions or synchronization errors. Framer and call statistics are available through standard API function calls.
