EDM01.05-12r1 DAG 3.7T Card User Manual http://www.endace.com 2.0 INSTALLING DAG 3.7T CARD A DAG 3.7T card can be installed in any free PCI slot. It is 5V tolerant Introduction and operates only in 32-bit 33MHz PCI mode. If placed into a slot rated for higher speeds the bus will automatically change to 33MHz, including any other devices sharing the bus.
Use the connector on the bracket if the POD is to be used outside of the chassis Only one Pod may be connected to the DAG 3.7T card at a time. The DAG 3.7T Pod has the 16 RJ45 T1/E1 connectors. The pin-out is:...

Capture at OC-12/STM-4 (622Mbps) rates and above may require a larger buffer. 128MB or more is suggested for Linux/FreeBSD. For the DAG 3.7T card Windows operating system the upper limit is 32MB. In Debian Linux the amount of memory reserved is changed by editing...
Common synchronization sources include GPS or CDMA (Cellular telephone) time receivers. Endace produces the TDS 2 Time Distribution Server modules and the TDS 6 units that enable multiple DAG cards to be connected to a single GPS or CDMA unit.
Endace Measurement Systems Limited EDM01.05-12r1 DAG 3.7T Card User Manual http://www.endace.com 5.1 Configuration Tool Usage The DUCK is very flexible, and can be used in several ways, with or Description without an external time reference source. It can accept synchronization from several input sources, and can also be made to drive its synchronization output from one of several sources.
Endace Measurement Systems Limited EDM01.05-12r1 DAG 3.7T Card User Manual http://www.endace.com 5.2.1 Single Card no Reference Time Synchronization When a single card is used with no external reference, the card can be Description synchronized to the host PC’s clock. The clock in most PC’s is not very accurate by itself, but the DUCK drifts smoothly at the same rate as the PC clock.
This is derived directly from a reference source, or distributed through the Endace TDS 2 [Time Distribution Server] module which allows a number of DAG cards to use a single receiver. The process is facilitated using TDS 6 expansion units coupled like a daisy-chain to a TDS 2 module.
