A feature of all Titan frames that employ a core board (e.g., T9160, T9116DSP, T9032DSP) is the ability to send a tone continuously out one channel while monitoring its level, a so-called "Circuit Test". Sometimes it is helpful during installation or troubleshooting in the field to turn on a tone to a selected Titan frame output so that this signal can be traced or detected in the field wiring or receiving equipment. The attached write-up explains how to do this using ViewProp.
