DAG 3.7T 16-Channel Network Monitoring Card
The Endace® DAG® 3.7T Network Monitoring Interface Card has been optimized for monitoring and interception with precision timestamping capability on up to sixteen T1/E1 network links.
Supported protocols include raw data (unmapped/ unframed), HDLC and ATM over as many as 512 sub-channels, channels and hyper-channels. The DAG 3.7T also supports Inverse Multiplex ATM (IMA) link aggregation, AAL2 and AAL5 segmentation and reassembly, and frame (HDLC), cell (ATM) and packet (AAL2/5) filtering based on user-defined filter rules. An onboard Intel® XScale™ processor provides the means to pre-process data prior to presentation to the monitoring software (or prior to transmission over a T1/E1 link)
With the power to see all traffic on these TDM network links, the DAG 3.7T enables network operators to develop solutions that inspect all traffic at the network edge for security threats, and precisely measure network performance and latency to improve end user’s experiences. This is particularly useful in mobile network backhaul links.
Highlights
- Sixteen channel Network Monitoring Interface Card for E1 and T1/J1 networks (receive and transmit).
- DAG technology provides 100% capture into host memory at full line rate for all packets from 5 to 2040 bytes.
- Software-selectable impedance control provides link termination or transparent-monitoring.
- Supports ATM and HDLC networks, plus RAW capture/ transmit.
- Full packet, header only or set length (truncated) packet capture.
- Precise packet time-stamping and clock synchronization by GPS for applications that require highly accurate measurements over long distances.
- Support for industry standard PCAP capture format (libPCAP / WinPCAP).
- Designed to integrate easily into existing server hardware with 32-bit PCI bus technology.
