VIAVI Allegro Call Generators and QoS Analysers

The latest solution in network load generation: Allegro & Fortissimo

Network Load Generators provide simultaneous functional and optional performance measurements of switch parameters and voice quality in carrier’s networks. Digital versions offer E1/T1 spans and VoIP signalling, a full Quality of Service (QoS) measurement package, and CAS, PRI, and SS7 signalling capabilities. The IP Voice Quality Tester comes with 10/100 baseT interfaces - further models are available for DS3 (45MBps), OC-3c (STM-1/155 Mbps) or analogue (POTS).

Highlights

• Compact, full-featured analog and digital call generator
• Optionally generation of new or modification of ready-made scripts
• Signaling protocols allowing for flexible adaption to upcoming applications
• New Voice Responder (AM3-QoS) offers economic termination of POTS lines at remote locations for active Voice QoS systems.

Applications

• 2-wire / POTS and 4-wire / handset interfaces
• Statistics of call attempts / completed calls, etc.
• Quality of Service (QoS) measurements designed to provide packet quality and voice quality scoring.
• "Golden voice" technology to measure packet loss, jitter, signal-to-noise ratio, clipping, and delay while simultaneously providing R-Factor, GMOS, GPSQM, and GPESQ scoring.
• Designed for operators and manufacturers integrating new services or verifying new switching platforms and modules, respectively.
• Voice SLAs can be validated, even through non-homogeneous networks.
• Simulation and Testing of various VoIP codec types
• Fax/Modem simulation and QoS testing
• Test of echo cancellers: simulation of echoes & analysis

Key Features

• 'Allegro' / ALG: small and portable call generator model
• 'Fortissimo' / NLG: Rack-mountable load generator for high volume call simulation
• Intuitive graphical user interface offers control of up to 32 call generator units
• Mix interfaces and protocols for tests in inhomogeneous TDM and NGN/VoIP networks.
