VF-TIMS Testing

The VF-TIMS (Voice Frequency Transmission Impairment Measurement Set) Module provides complete voice frequency testing in the analog voice range of 50 to 20,000Hz. It performs noise and signal-to-noise ratio measurement, power influence, and impulse noise measurement by placing different filters on the receiver. The VF-TIMS Module can also emulate both CO and PBX for direct inward dialing (loop reverse battery) and ground start signaling.
