Acterna ANT-20SE

Advanced Network Tester ªSpeed Evolutionº± SONET

As digital communications networks ex-

pand, the number of network operators is

growing too, and not just due to providers

merging across boarders. Different net-

works such as Cellular, CATV and Internet

are converging too. Nowadays, customers

demand next-to-perfect network availa-

bility, and a top-level transmission quality

has become a given.

ANT-20SE: A design

future-proofed for success

Powerful, precise test capability or simple

operation? PDH, SDH, SONET with all bit

rates from 1.5 Mbit/s to 10 Gbit/s, or ATM?

Don't worry about alternatives! You dont't

have to choose. ANT-20SE delivers sophis-

ticated, precision testing that is easy to use

even in the most demanding environment

for all the above bit rates and for ATM.

In addition comprehensive jitter/wander

measurements up to OC-48 in complete

compliance with the ITU-T Rec. O.172 for

comparable, insightful and accurate mea-

surement results.

The remote operation facilities, gives you

the opportunity to reduce your costs e.g.

operating the instrument from any windows

PC via modem or Ethernet LAN. Always

ready for new standards, higher bit rates

and the intelligent system components of

the future the ANT-20SE is at the forefront

of network installation and manufacturing

applications. Now with the ANT-10Gig a

subset of the ANT-20SE, it is taking you

one step further allowing the analysis of

OC-192/STM-64 signal structures.

One outstanding feature of the ANT-20

test solution has always been its ease of

use,

thanks to the very large display and

graphical

user interface based on Windows

98. The new ANT-20SE is even better since

the size and brightness of the display have

been further improved. The high speed

access buttons are another useful detail,

allowing you to rapidly launch commonly

occurring measurements.

The test solution that sets

the pace in analyzing digital

communications systems

Multi-rate transmission

testing from DS1 to OC-192

Modular platform offering

SONET, DSn, SDH and ATM

capabilities

Built-in Pentium PC and

Windows 98 user interface for

easy processing of test results

Complemented by a lot of

easy-access, automated test

features

Delay measurement Delay measurements are used for aligning satellite hops and testing the maximum permitted delay times for storage exchange and cross-connect systems and for checking the loop circuits in regenerators. The ANT-20SE measures the time taken to transmit the test pattern from the generator through the section under test and back to the receiver.

ATM Options ATM Basic BN 3060/90.50 General Adjustable test channel from 0 to 150 Mbit/s In ATM network elements, user channels are monitored with the UPC (usage parameter control). The sensors of the control instance can be quickly checked if the bandwidth of a test channel exceeds the set threshold in the network element. For all measurements, the test channel in the ANT-20SE is set on-line. Settings are made directly with a control (Figure 15) which shows the bandwidth in Mbit/s, Cells/s or %.

ATM QoS test with four different SVCs The ANT-20SE with BAG can perform SVC and PVC tests on up to four circuits simultaneously. Multi-channel services, such as those used for multimedia applications, can thus be simulated. Any channel type can be selected from the database or newly defined for each channel. Real-time measurements conform to the ITU-T O.191 standard which defines the test cell format and the test algorithm. Important source parameters can be regulated on-line during the test.

CATS DLL The CATS DLL runs on the calling PC (under Windows 2000, Me, NT or WIN95/98) and communicates with the ANT-20SE via a standard remote control interface (RS232, GPIB or TCP/IP). The customer software runs on the same PC and communicates directly with the DLL. CATS ANT-20 remote controlled via TCP/IP CATS TCP/IP is a different way of controlling the ANT-20SE in an automated environment. It is a special version of the CATS Test Sequencer that runs on the ANT-20SE itself.
