A unique combination of physical line and service verification

Acterna DSL-370 DSL Copper and Services Tester

Network providers must operate several

DSL variants simultaneously to meet

the demands of their residential and

business customers within the con-

straints of their underlying access

network. These organizations also

need to be capable of introducing new

services at any time. However, most of

the available tools do not support all

the possible DSL options or stages

involved in providing the customer

with a DSL service.

The Acterna DSL-370 delivers a high

degree of flexibility by providing physi-

cal line testing and modem testing in a

single instrument. The DSL-370 is the

only instrument available on the market

today that can test both the physical

and service layers of the network with

equal ease.

The DSL-370 is the only tool on the

market combining such comprehensive

and accurate testing for qualifying,

commissioning and troubleshooting

xDSL service provisioning and mainte-

nance. It is the antidote to broadband

network provisioning inefficiencies.

Highlights

– Caters for ADSL over ISDN, ADSL

over POTS and G.SHDSL with dual

exchangeable modems

– Tests all elements of DSL service

in one visit

– Reduces equipment and staff costs

– Increases return on DSL investments

– Provides comprehensive testing

and improved speed-to-revenue

Provides powerful combination ofphysical line and modem testingBy using the DSL-370’s icon driven

menu, test criteria can be selected

quickly and simply (see figure 1).

The DSL-370 provides complete

automated wideband copper quali-

fication for xDSL, ISDN and POTS up to

2 MHz and shows at a glance whether

new service offerings are technically

possible. This enables installers and

maintenance technicians to verify trans-

mission and physical characteristics.

It can also determine the characteristics

of copper connections quickly and sim-

ply. The DSL-370 has all the power of

Acterna’s DSL-311 and DSL-322

for physical copper testing plus the

addition of a digital volt/Ohm meter,

capacitance for distance to opens

and balance.

Ensures all flavors of xDSL catered forwith dual exchangeable modemsThis instrument’s dual user-exchange-

able modems make it the perfect tool

for customers using more than one

flavor of xDSL. The instrument also

displays major service parameters.

An LED indicates successful synchro-

nization between the DSL-370 and

the DSLAM.

The instrument verifies the ability

of the physical layer to support the

desired service. However, successful

turn-up is not just about connecting

to the DSLAM. The optional modem

modules also empower technicians

to validate the potential quality and

reliability of connections to the

Internet and other service providers.

The modem options currently available

are: ADSL over POTS, ADSL over ISDN

and G.SHDSL.

Tests all elements of DSL service in one visitThe key to the DSL-370’s success is

its ability to test all elements of a DSL

service during a single visit. The instru-

ment’s reputation as a one-man,

one-box solution is further enhanced

by its interoperability with Acterna’s

DSL-311 and DSL-322 copper test tools.

When used with either of these com-

plementary instruments, the DSL-370

provides a powerful end-to-end line

test solution. The use of automatic

test sequences (figure 2) allow the

user to set up templates for a simple

pass/fail response.

Reduces equipment and staff costsThe DSL-370’s straightforward graphical

user interface simplifies the testing

process, thus reduces the amount of

training needed for comprehensive

DSL testing. In addition, in-built auto-

mated features combined with support

for all phases of DSL service deploy-

ment, reduce the number of installers

required to provision and maintain

service as well as making it possible

for non-experts to operate tests.

Once the tests have been performed,

the DSL-370 delivers the results in

tabular or graphical formats (as shown

in figure 3) that can be interpreted on

the spot and saved for transfer to a PC

for reportingpurposes.TheDSL-370

includes all necessary accessories for

use in the field. It is supplied as a single

instrument in a soft carrying case.

Copper testingSingle-ended measurements

The DSL-370 provides everything

needed to test copper wire pairs.

Just one instrument is sufficient for

most measurements.

End-to-end measurements

To qualify lines for ISDN, HDSL, SDSL,

ADSL services, etc. Additional end-to-

end measurements are needed.

The device at the far end can be a

DSL-370, DSL-322 or DSL-311.

Testing analog connection lines

The DSL-370 provides additional

extended functions for qualifying

and troubleshooting copper wire pairs.

This allows the technician to ensure

that the service quality demanded

by the customer is provided.
