    Chapter 1: Introduction Overview The installation of the Endace DAG 3.7D card on a PC begins with installing the operating system and the Endace software. This is followed by fitting the card and connecting the ports. The characteristics include card architecture, extended functions, and system requirements.

  • Page 8: Card Description

    All packet records are written to host PC memory during capture operations. Serial PDH data is received by the DAG 3.7D card co-axial interfaces, and fed into dual DS3/E3 framer. Network data is then fed to the FPGA which also contains the DUCK timestamp engine.

  • Page 9: Extended Functions

    The current firmware only supports bit synchronisations HDLC demapping. Extended The functionality of the DAG 3.7D card can be extended in many ways. A physical transmit path is provided on the card so that packet organisation is Functions possible, requiring special firmware images.

  • Page 23: Chapter 5: Synchronizing Clock Time

    Common synchronisation 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.
  • Page 24 EDM01-06: DAG 3.7D Card User Guide Configuration Description Tools The DUCK is very flexible, and can be used with or without an external time reference source. It can accept synchronisation from several input sources, and also be made to drive its synchronisation output from one of several sources.

This is derived directly from a reference source, or distributed through the Endace TDS 2 [Time Distribution Server] module which allows two DAG cards to use a single receiver. More cards can be accommodated by daisy-chaining TDS-6 expansion units to the TDS-2 unit, each providing outputs for an additional 6 DAG cards.
