What Is It?
The Allegro is a network load generator that simulates telephony subscribers placing calls into
the network. 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 load in
a dedicated lab environment.

What Does It Do?
The Ameritec Allegro has the ability to simulate subscriber calls. This network 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, CAS and SS7 circuits. Up to 4 T1/E1
circuits can be accommodated in a single unit.

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, G-PESQ, 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.

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 Allegro unit using Conductor.
 

What Can It Test?

Applications that previously were too costly to test automatically can now be easily
automated with Allegro.

• Central Office or PBX Switches and Network

• 3rd Generation Voice Over Packet Systems

• Intelligent Network (IN) Applications

• Voice Mail Systems

• Computer Telephony Integration (CTI) systems and applications

• Automatic Call Distribution (ACD) systems

• Paging Systems

• Etc.
