Introduction

Overview

The Endace DAG 3.7D card provides the means to transfer data at the full speed of the

network into the memory of the host PC, with zero packet loss in even worst-case conditions.

Further, unlike a Network Interface Card (NIC), Endace products actively manage the

movement of network data into memory while only consuming a minimal amount of the

host computer's resources. The full attention of the CPU remains focused on the analysis of

incoming data without a constant stream of interruptions as new packets arrive from the

network. For a busy network link, this feature has a turbo-charging effect similar to that of

adding a second CPU to the system.

The DAG 3.7D is a two port. PCI card that allows capture and transmission of data. It

supports packet and cell capture for DS3/E3, ATM and HDLC networks. It has two

interfaces which may be used simultaneously to allow a single card to monitor either one or

both directions of a full duplex link.

Card Features

The following features are available on this DAG card. Note: Different firmware images

may be required. Not all features are available on each firmware image. For further

information on which feature is available in what firmware image, see Firmware images

(page ).

•DS3, E3, ATM and HDLC

•Frame Relay

•Kentrox Subrate

•Cisco Fractional

EDM01-16v5 DAG_3.7D_Card_User_Guide

System Requirements

General

The minimum system requirements for the DAG 3.7D card are:

•A computer, with at least a Intel Xeon 1.8GHz or faster and a minimum of 1GB RAM.

•At least one free PCI slot supporting 33 MHz operation.

•Software distribution requires 60MB free space.

•For details of the supported operating systems, see one of the following documents:

•EDM04-01 DAG Software Installation Guide

•Current release notes - See the Documentation CD or the Endace support website

at https://www.endace.com/support

Operating System

This document assumes you are installing the DAG 3.7D card in a computer which already

has an operating system installed. To install refer to EDM04-01 DAG Software Installation

Guide. All related documentation is included on the CD shipped with the DAG 3.7D card.

Other Systems

For advice on using an operating system that is substantially different from any of those

specified above, please contact Endace Customer Support at supp[email protected].

EDM01-16v5 DAG_3.7D_Card_User_Guide

Card Description

The DAG 3.7D card has two DS3/E3 co-axial interfaces each of which are able to receive and

transmit. It is capable of capturing 100% of traffic at full line rate over ATM, HDLC, frame

relay and channelized networks.

Note: Transmit is not currently supported on the DAG 3.7D card.

The DAG 3.7D supports Kentrox format subrate DS3 but requires a specific image to do so.

Please contact Endace Technical Support at [email protected] for more information.

The DAG 3.7D card is shown below:

The key features of the card are:

•Four SMB format DS3/E3 network interfaces (2 x receive, 2 x transmit).

•100% capture into host memory of IP packets between 40 and 1500 bytes.

•Supports DSX-3 monitor mode.

•Full, header only, or variable length packet capture.

•Conditioned clock with 1-PPS input and local synchronization capability.

•32-bit 33MHz PCI 2.9 compliant bus interface with 3.3V signalling.

Battery removal – don’t do it!

Removing the battery from a DAG card voids your warranty.

Removing the battery from a DAG card will cause the loss of encryption key used to decode

the DAG card's firmware. Once the encryption key is lost the DAG card must be returned to

Endace for reprogramming.

The battery in this product is expected to last a minimum of 10 years.

Caution

Risk of explosion if the battery is replaced by an incorrect type.

Dispose of used batteries carefully.

EDM01-16v5 DAG_3.7D_Card_User_Guide

Card Architecture

Serial PDH data received by the two coaxial interfaces feeds into the dual DS3/E3 framer.

The network data is then directed to the Field Programmable Gate Array (FPGA). The FPGA

also contains the DAG Universal Clock Kit (DUCK) timestamp engine which provides high

resolution per-packet timestamps which can be accurately synchronized.

The close association of these two components means that packets or cells can be time-

stamped very accurately. The time stamped packet records are stored in the FIFO which

interfaces to the PCI bus via the FPGA.

Note: For further information on the DUCK and time synchronizing, see Synchronizing

Clock Time 39(page ).

All packet records are written to host PC memory during capture operations.

The diagram below shows the DAG 3.7D card's major components and flow of data:

EDM01-16v5 DAG_3.7D_Card_User_Guide

Line Types

It is important that you understand the physical characteristics of the network to which you

want to connect. If your configuration settings do not match your network, the DAG 3.7D

card will not function as expected.

There are various Ethernet line speeds and corresponding protocols which are identified

using the IEEE naming convention. Each line speed has a set of requirements associated with

it relating to the type of cable, maximum allowable distance, etc.

Note: If you are unsure about which of the options listed below to apply to your network,

please contact your Network Administrator for further information.

Supported Types

The line characteristics supported by the DAG 3.7D card are described below.

Line Types Description

DS3 Digital Signal 3 - North American digital standard 44.736Mbps (also referred to as

T3).

E3 European digital standard 34.38Mbps

Line Rate Description

Full The full speed of the network, either DS3 or E3 as described above.

Fractional A fraction of the full speed of the network. There are several proprietary fractional

rates available. Please contact your network provider for further details.

The DAG 3.7D supports fractional E3 only and the rate is represented as the

number of timeslots used out of a possible 95.

Data Type Description

ATM Asynchronous Transfer Mode which carries data in small fixed sized cells.

HDLC High-level Data Link Control which carries data in variable sized frames.

Encoding Type Description

B3ZS Bipolar with Three Zero Substitution (DS3 only)

HDB3 Hi-Density Bipolar Three Zeros (E3 only)
