Atec AM2-DE, AM2DX, AM2A, AM2P, AM2D User Manual

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.

Ameritec’s AM2 Niagara®family of products is comprised of fully self-contained portable test instruments designed to meet the rigid demands of today’s telephony applications developer in both laboratory and field applications. The AM2 Niagara, simply put, makes telephone calls -- and lots of them! Each AM2 Niagara unit allows interfacing to different line types. One model interfaces to Analog POTS lines, another to Analog P-Phones lines, others to T1, E1, PRI, BRI, and SS7. The AM2 Niagara allows users to develop a test environment with the ability to test highly complex call scenarios.
AM2-A Analog Call Generator provides physical interfaces for 64 analog line and 160 total lines with the AM2E-A Expansion unit.
AM2-P P-Phone Call Generator provides the physical interface for 32 EBS lines.
AM2-B Basic Rate ISDN Call Generator provides physical interfaces for 32 BRI/BRA ISDN U-Interface (2B1Q) lines.
AM2-D/De T1/E1 Digital Call Generators provide physical interfaces for four 1.544 Mbps T1 CAS trunks or four 2.048 Mbps E1 CAS trunks.
AM2-DX/DXe Primary Rate ISDN Call Generators provide physical interfaces for four 1.544 Mbps T1 CCS trunks or four 2.048 Mbps E1 CCS trunks.
AM2-S7/S7e SS7 Call Generators provide physical interfaces for one to four 1.544 Mbps T1 CCS trunks or
2.048 Mbps E1 CCS trunks and supports up to eight SS7 signaling links.
AM2 Niagara units are ideally suited for testing complex, interactive applications under high call loads on dozens of lines simultaneously in the field or a dedicated lab environment.
Applications that previously were too costly to test automatically can be easily automated with the AM2 Niagara.
Such test applications include:
Central Office or PBX Switches and Networks
Voice Over Packet (VoFR, VoIP) Systems
Intelligent Network (IN) applications
Voice Mail systems
Computer Telephony Integration (CTI) systems and applications
Automatic Call Distribution (ACD) systems
Interactive Voice Response (IVR) systems
Paging systems
Each AM2 Niagara can simulate one to hundreds of telephony subscribers. The actions of each simulated subscriber are independently controlled through unique parameter fields defined in user programmed Call Scripts.
Scripts define calling patterns and can simulate practically any action a live caller can perform. Scripts also simulate multiple subscribers allowing testing of multiple-party calls such as conference calling.
Signaling: All interface specific signaling functions supported through Call Scripts and user programmable signaling protocols.
Dialing: Multiple unlimited length dial strings, multiple dialing types, including in-band end-to-end signaling (e.g. DTMF digits for interactive applications).
Digit decoding: Decode in-band DTMF or MF digits.
Tone Send: Send pre-programmed single frequency tones.
Tone Receive: Detect any single frequency tone.
Path Verification: Comprehensive two-way verification of multiple party voice and data path connections via in-band sequences, BERT patterns, X.25 packet data, or packet drop detection (VoP).
Voice Replay: Optional feature allowing replay of pre-recorded audio samples on demand.
ADSI: Optional feature permits the testing of caller ID functionality.
Delays: Event-to-Event delay measurements, round trip delays (VoP).

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.
