Key Features
-
2-Channel Operation: Allows simultaneous testing of two separate telephone lines or devices, supporting both analog and digital signaling simulation.
-
Network Emulation: Simulates real-world telephone network conditions, including loop length, impedance matching, and signal attenuation.
-
Power Supply: Features a wide input range of 100-240VAC, making it suitable for global deployment without the need for external voltage converters.
-
Application: Often utilized in Automated Test Equipment (ATE) systems or as a standalone bench-top device for Voice over IP (VoIP) gateways, PABX systems, and legacy analog terminals.
