` Fortissimo is the world's smallest, high-capacity network load generation product designed to test and qualify the voice and packet network. ` Fortissimo speeds up your system integration, functional and performance testing at an unbeatable price/performance ratio. ` Fortissimo 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 Fortissimo family of network load generators represents a significant techno- logical advancement in high-capacity 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 integra- tion or revenue and quality assurance will also enjoy the functionality, ergonom- ics and costs of this solution.
