Ameritec AM2

The Ameritec AM2 Niagara is a telephone line simulator and bulk call generator engineered for testing telecommunications equipment across development, production, quality assurance, and regression testing environments. It simulates diverse line conditions and generates high-volume call scenarios, enabling evaluation of complex subscriber behaviors. The system supports flexible interface options and advanced scripting capabilities to meet rigorous telephony testing demands.
