Protection Against Harmful Interference
When present on equipment this manual pertains to, the statement "This device complies with part 15 of the FCC rules"
specifies the equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15
of the Federal Communications Commission [FCC] Rules.
These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a
commercial environment.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.
Extra Components and Materials
The product that this manual pertains to may include extra components and materials that are not essential to its basic
operation, but are necessary to ensure compliance to the product standards required by the United States Federal
Communications Commission, and the European EMC Directive. Modification or removal of these components and/or
materials, is liable to cause non compliance to these standards, and in doing so invalidate the user’s right to operate this
equipment in a Class A industrial environment.

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.
This document, DAG Card 3.7D User Guide is available when the
installation CD is placed in a running Windows PC.
Purpose
Description
The purpose of this DAG Card installation guide is to describe:
•Installing the DAG3.7D
•Confidence Testing
•Running Data Capture
•Synchronising Clock Time
•Data Formats Overview
Pre-requisites
This document presumes the DAG card is being installed in a PC already
configured with an operating system.
A copy of the Debian Linux 3.0 r4 is available as a bootable ISO image on
one of the CD's shipped with the DAG card.
To install on the Linux/FreeBSD operating system, follow the instructions
in the document EDM04-01 Endace Software Installation Manual.
To install on a Windows operating system, follow the instructions in the
document EDM04-02 Endace Windows Installation Manual.

Card
Description
The DAG cards are PCI-bus cards designed for cell and packet capture and
generation on IP networks.
The DAG 3.7D card has dual DS3/E3 co-axial interface, both receive and
transmit and is shown below:
Card
Architecture
Description
Because of component close association, packets or cells are time-stamped
accurately. Time stamped packet records are stored in the FPGA, which
interfaces to the PCI bus.
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. The close association of these two components means
that packets or cells can be time-stamped very accurately.

Card
Architecture
(cont.)
The diagram below shows the DAG 3.7D card major components and
process flow.
Time stamped packet or cell records are stored in a FIFO.
The DAG 3.7D can demap either ADM (ATM Direct Mapped) ATM cells,
PLCP (Payload Layer Convergence Protocol) ATM cells, PPP
encapsulations, HDLC (High-Level Data Link Control) and Frame Relay.
The DAG3.7D also supports subrate DS3 for Kentrox data encapsulation
formats but requires a specific image to do so. Please contact Endace
Customer Support at support@endace.com for more information.
Records are then transferred from the FIFO into the FPGA, which has
interfaces to the PCI bus.
The current firmware only supports bit synchronisations HDLC
demapping.
Extended
Functions
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
possible, requiring special firmware images.
The framer is normally set up to map DS3 payloads, but other mappings are
possible.
To discuss the use of other extended features contact the Endace customer
support team at support@endace.com

System
Requirements
General
The DAG 3.7D card and associated data capture system minimum
operating requirements are:
•PC, at least Pentium II 400 MHz, Intel 440BX, GX or newer chip set
•Minimum of 128 MB RAM
•At least two free PCI free slot with 3.3V and 5V power
•Software distribution free space of 30MB
•Endace Linux Install CD requires 6GB
Operating System
For convenience, a Debian 3.1 Sarge Linux system is included on the
Endace Software Install CD. Endace currently supports Windows XP,
Windows Server 2000, Windows Server 2003, FreeBSD, RHEL 3.0, RHEL
4.0 and Debian Linux operating systems.
Other Systems
For advice on using a system substantially different from that specified
above, contact Endace support at support@endace.com
