What Is It?
The Fortissimo is an OC3/STM-1 multiplexor that works in conjunction with 1-3 Fortissimo
NLG-DS3 units to create an OC3 or STM-1 span. The unit gives the user flexibility to serve a wide
range of applications associated with switch and network testing. Ideally suited to allow the user
to develop a test environment with the ability to test highly complex call scenarios and
interactive applications under high call loads on hundreds of lines simultaneously in a dedicated
lab environment.
 

What Does It Do?
The Ameritec Fortissimo has the ability to simulate high volumes of subscriber calls. This high
volume of bulk call generation can be combined with complex call testing capability. Through the
use of user defined call scripts and line protocols, users can tailor test scenarios to meet a wide
range of testing requirements.

Subscribers can be simulated on T1, E1, Primary Rate ISDN, and SS7 circuits via software
selectable parameters. The unit supports one OC3 or STM-1 span complete with virtual tributary
functionality.
 

How Does It Work?
The actions of each simulated subscriber are independently controlled through unique parameter
fields defined in user programmed Call Scripts. Call Scripts include capabilities for testing
signaling, dialing, Voice over Packet, QoS (GMOS, G-PSQM, R-Factor) digit decoding, tone
sending, path verification, and tone receive. The Scripts define calling patterns and can simulate
practically any action a live caller can perform. Scripts can also simulate multiple subscribers
allowing testing of multiple-party calls such as conference calling.

The Ameritec Conductor GUI, a Windows® based Graphical User Interface, allows the user to
create test systems. The user is now able to create a battery of tests, create traffic profiles, load
test cases, view test results and create reports.

With the addition of the Ameritec XpresScript the user is able to develop sophisticated test
scripts by simply drawing the test sequence. Call Scripts are easily developed by dragging,
dropping and interconnecting icons to create a graphical Call Flow Diagram. This Call Flow
Diagram can easily be loaded into the Fortissimo using the Conductor.
 

What Can It Test?
Applications that previously were too costly to test automatically can now be easily automated
with the Fortissmo.
