ADSL CARDS FOR MULTI INTERFACE TESTER D2071

OVERVIEW

The two modules ADSL71 and ADSL71-I must be combined with the

Aethra

xDSL multi-interface tester D2071.

They cover completely the ADSL technology, both ADSL over POTS

(ADSL71 card) and ADSL over ISDN (ADSL71-I card).

Aethra supplies these two cards with all the variations to ADSL like G.DMT,

G.Lite, Full Rate, Multimode, etc. in order to be ready to face evey kind of

link during an installation or troubleshooting of a line.

Through the connection test, the ADSL link can be analyzed in depth,

thanks to parameters characterizing the line like Fast/Interleaved bit rate,

Noise Margin, Attenuation and many others.

The SMART STATUS

feature allows the user, through the pression of a

single button, to display the DMT bit per tone in graphical and table format;

this is useful to investigate the portions of frequency spectrum negatively

influenced by crosstalk or any other noise.

The user can perform both high impedance and "during simulation" moni-

toring; then, all data captured can be analyzed either directly at customer

premise (through the powerful onboard decoding) or by using PC108 for

Windows

software.

For what concerns the ATM stack, the implementation of the OAM cells is

provided while AAL-5 is the ATM Adaptation Layer chosen for the packets

generation test. On this subject, pages dealing with errors and statistics are

available in order to allow a detailed analysis of the ATM layer.

The IP layer can be managed through the IP Ping test and the IP Generate

Traffic. While the former checks the connection to the Internet Provider, the

reachability of a remote host, the Trace Route and the response times, the

latter allows the simulation of a data transfer between two hosts. This very

useful because the user is able to measure the throughput of the connec-

tion in progress.

There are two operating modes: the ATU-R one simulates the user's side;

the Through mode (Bridge) one carries out a simulation of the user's

modem: this is achieved by placing the module and the main unit D2071

between the host and the CO side.
