TERLE The telco echo return loss enhancement (TERLE) meter shows the loss through the telephone echo cancellation process. It is the ratio of the two levels.

Threshold The upper or lower level at which a signal processing mechanism begins or terminates operation.

Transmit audio Audio being sent to the telephone line (To Telco).

Unit properties The Unit Properties window opens when you add a new unit to the site. It allows you to enter information about the unit as well as configure the communication and security settings.

Virtual reference Virtual references are echo cancellation reference points. Multiple signals can be included in each of the four virtual references thus allowing you to reference multiple signals without sacrificing an analog output. You can open the Virtual Reference window from the G-Ware toolbar or from the Acoustic Echo Cancellation window.

White Noise Acoustical noise with equal energy throughout a given frequency

range.
