Abacus100 speech quality analyzer

Abacus100 speech quality analyzer

Spirent's Abacus100 can test the scalability, performance, interoperability, and voice quality of simulated voice, triple play services (voice, video, and data over IP), and LTE voice (VoLTE) before and during deployment, avoiding the hassle of using multiple testing tools.

Abacus can accelerate project progress while utilizing the complexity of the real world to improve product quality through testing synchronized scenarios, identifying and resolving issues related to load handling, functionality, and interoperability. As it no longer requires multiple types of equipment, it can effectively reduce the overall cost of testing.
