AM2 Niagara products feature a multiprocessor architecture, which guarantees that call volume is not affected by
the number of operating channels or the nature of the tests
that the user chooses to perform. Extensive use of high
speed microprocessors and Digital Signal Processors
(DSPs) make AM2 Niagara versatile, accurate and fast.
All tone detectors are based on DSPs. Never needing calibration, AM2 Niagara systems will last well into the next
generation of switching systems.
To maintain the maximum level of performance, functionality and flexibility, every AM2 Niagara is powered by a
32-bit RISC processor, controlled via user defined scripts
and protocols and managed via FeatureCall, a Windows
based graphical user interface. In addition, every line or
channel in an AM2 Niagara is served by “local” DSPs to
identify call progress tones, detect digits and to verify the
voice path after a connection has been established. The
combination of these capabilities allows the user of AM2
Niagara to create the complex call testing applications necessary to develop and test today’s communication systems
and applications.

Call Scripts &
Call Programs
Call Scripts are templates
defining the actions of a single
caller. The Call Script defines
calling patterns, voice path confirmation requirements and the
supplemental tones and digits used
in simple applications and complex
calling scenarios. A number of scripts
for common testing needs are provided
with each unit.
Using the Call Script as a template, call
variables (parameters) such as “dialed
number” are added to create a Call
Program. There is a separate Call
Program for each line or channel
in the unit. Call variables can be
changed by the user to build
new Call Programs, even with
the unit running tests. All Call
Programs are stored in
non-volatile memory.
User Defined Functionality
All AM2 Niagaras are furnished with front panel controls and FeatureCall, Ameritec’s Windows based
Graphical User Interface (GUI) that provides control for test applications with a single AM2 or multiple units
via an RS232 port or over a TCP/IP LAN. FeatureCall provides an easy method to configure units,
create tests parameters and run test cases.
Customizing Call Scripts & Protocols
The AM2 allows users to develop scripts and protocols to meet their specific
needs. Custom scripts and protocols may be developed by simply modifying
the ones supplied with the unit, or new ones may be developed from the ground
up using available tools.
Call Scripts are developed by using either ScriptMate, Ameritec’s Graphical
test script generator tool or in a standard Text Editor. Scripts can be automatically downloaded to a unit through FeatureCall’s Call Setup Script window.
Protocols can be developed or customized using Ameritec’s Protocol
Development Kit. The kit runs on a personal computer and consists of a
protocol development guide and an assembler/linker.
Automation Interface
As an alternative to the front panel control or FeatureCall, the AM2 provides
a control interface for users with proprietary test systems software. The communication is a command line format that allows easy integration of the AM2
into an automated test system.
Protocol Assignments
The AM2 uses Protocol State Tables to translate the call instructions from the
Call Program Test Set to a sequence of signaling events that are recognized by
the network. The AM2 can support multiple protocols running simultaneously
and the user has the ability to assign them to lines and channels as necessary.
Each AM2 is supplied with protocols that are standard for their model type.
Statistics & Error Messages
Statistics are automatically accumulated in the unit.
Reports include totals for each line/channel, the
number of errors recorded as well as totals for the
system. The amount of statistical information reported
is at the control of the user. Reports may be output to
a printer or computer.
The Real Time Error Log automatically records
error conditions occurring in the running Test Set.
Errors are reported on call setup, call completion and
other conditions defined by Protocol State Table and
Call Script. Each error record contains the Call
Program name, line or channel affected, time and date
of the error, the error type, and a short description of
the error. The report also contains the start and stop
times of the Test Set.
Call Program Test Sets
A Call Program Test Set consists of a collection of
Call Programs that have been assigned to various lines
or channels for convenient pre-programmed or
automated testing.
