Allegro Desktop Network Call Generators ♦ Allegro is the world’s smallest, full-featured network load generation product designed to test and qualify the voice and packet network. ♦ Allegro speeds up your system integration, functional and performance testing at an unbeatable price/performance ratio. ♦ Allegro is designed to place calls to or receive calls from other Allegro, Fortissimo or AM3-QoS units to provide a complete test system of call generation and Quality of Service (QoS) measurements. The Allegro family of network load generators represents a significant technological advancement in desktop call generation. Designed to meet the requirements of today's developer of both legacy and new generation switches including hardware and software modules. Operators focusing on system integration or revenue and quality assurance will also enjoy the functionality, ergonomics and costs of this solution. The Allegro packs the power of 8 simultaneous SIP/MGCP calls, up to 4 × T1/E1 spans or 4 × analog POTS (loop/ground/fax/data modem) circuits in a unit that sits inconspicuously on a desktop. The Allegro comes in three versions - an Ethernet VoIP (SIP/MGCP) configuration, a multi-span T1/E1 configuration, or a 4-line analog configuration. The Allegro IP Voice Quality Tester (VQT) is capable of generating signaling and media traffic on 8 unique IP sessions. The QoS measurement package is standard on this unit. The digital version ships complete with 2 T1/E1 software selectable spans, a full quality of service (QoS) measurement package and CAS, PRI and SS7 signaling capabilities. Optionally, the unit may be configured for 3 or 4 digital spans. The analog version supports 4 analog circuits, complete with loop and ground start signaling, fax and data modem operation and Ameritec's industry leading QoS measurement package. Operation The Allegro products allow the developer to simulate various types of network traffic on a select number of spans or lines without having to go to the expense of purchasing large-scale units. Maintaining full testing flexibility on a smaller line count is the premise behind Allegro. Each Allegro is controlled via a PC workstation over a 10/100 MB Ethernet port and utilizes a Conductor graphical user interface (GUI) that is intuitive and easy to use. Alternately, a command set option allows the user to remotely control units via a Telnet or Tcl session for test automation applications. Full scripting of call scenarios is accommodated and manipulation of signaling protocols is provided to allow the user to fully test and debug equipment under test before releasing product to the next stage of development. Audio monitoring and capture is provided on the Allegro to complete the testing phase so that a developer can further verify the integrity of any call scenario. Measurements Long known for providing the most comprehensive set of measurements in the call generation industry, Ameritec has Applications incorporated into every Allegro product the ability to simultaneously measure traditional call statistics such as calls originated and completed ♦ Load Generation as well as a comprehensive set of QoS measurements designed to ♦ Cable Telephony, FTTP, PON, VoDSL provide packet quality and voice quality scoring. This complete set of ♦ Automated Testing via Telnet and Tcl measurements provides the developer with PSTN to packet network ♦ Fax and Data Modem Testing correlation scores. The ability to utilize our GoldenVoice technology to ♦ Quality of Service Testing measure packet loss, jitter, signal to noise ratio, clipping and delay ♦ CLASS Calling Feature Testing while simultaneously providing R-factor, GMOS, G-PSQM, G-PESQ, ♦ Live Network Testing and G-PESQ-LQ scoring on all lines makes this product an invaluable ♦ Point of Sale Terminal Testing development tool. ♦ Voicemail, IVR Testing ♦ Echo Testing Enhanced Features A modem QoS feature verifies accurate detection and transport of Fax, ♦ Wideband Voice Testing and Verification Modem and TTY/TDD signals in pass-through scenarios. Synchronized call scripts provide the ability to test complex call scenarios such as A->B;B->A, and CLASS features such as conference calling, call waiting, etc. Live Network Testing Full wideband audio testing allows the Allegro IP to ensure that High Definition (HD) voice quality is operational. Real fax and data modem emulation is fully supported on Allegro analog units to provide complete network testing. Configuration Upon power up, each Allegro prompts the user to recall previously stored test configurations from the PC. This includes the type of call programs that the user desires to run and any parameter settings that are required for a specific test. At the completion of any test, the user is prompted to store the unit’s configuration so that it may later be retrieved to verify test integrity or re-run a previous test. Virtually, an unlimited number of these configurations can be stored on the workstation for easy recall. Performance While this may be the industry’s smallest network load generator, ounce for ounce it provides highest performance. Utilizing independent resources, each Allegro can generate as many calls as your equipment can support. The Allegro can configure nearly every parameter associated with the generation or answering of a call and therefore it is possible to test for load related issues as well as fundamental integrity issues. Additionally, as many as 32 Allegro ♦ Provides Call Detail Records with Timestamps units can be used side by side to increase call volumes without ♦ Calling #, Called #, QoS Measurements significantly increasing your investment. ♦ Active Call Completion and QoS Testing Conductor Graphical User Interface General Characteristics Voice Channel Functions User Interface Windows 7, Vista, XP based GUI Detectors Tone detectors are based on digital signal processors (DSP) 1 per Ethernet Port One RJ45 connector and two LED channel indicators per network interface 10/100 BaseT interface Call Progress Detectors One detector per line Complies with IEEE 802.3 Detects dial tone, busy, reorder, ring, ringback, supervision Dimensions 2” Wide x 5” High x 7” Deep Power 90 – 264 VAC, 47 to 65 Hz Path Confirmation One receiver per line Accuracy: 1%, +/- 10 Hz Weight 2 Pounds (0.9kg) Single Frequency Tone 64 Selectable tones Generator Call Programs and Scripts Voice over Packet Features Commonly used scripts supplied Voice Path Confirmation GoldenVoice signal designed to pass with unit through vocoder Scripts created and downloaded Packet Drop Out Count Count lost packets for frame sizes of 5, from workstation or PC 10, 15, 20, 30, 40 and 100 ms Measure Delay Round trip delay +/- 10 ms accuracy One way delay +/- 5 ms accuracy System Measure Clipping Peak and average clipping of standard Capacity 8 unique IP sessions, 4 analog reference with +/- 5 ms accuracy lines, or 2 digital spans (opt. 4) Jitter Peak and average jitter of standard reference with +/- 5 ms accuracy Call Volume Typically 500 confirmed calls per SNR Average and maximum SNR received hour per line (DTMF dialing, tone (from 0 to 39 dB) ID confirmation, 2 unpaired lines) Signal Energy Average and maximum GoldenVoice energy received (0 to –50 dBm) Line Types -
