Teletech’s TX916 Loop-a-Line operates on two 9V batteries (Not Included) for the PROBE and the OSCILLATOR.Together these devices are used by the communicationtechnician to aid in telephone installation and cable faultlocation and repair.

A communication technician can work unassisted byremotely controlling an OSCILLATOR (located at theexchange MDF or street cabinet) from a PROBE located onthe same line up to 20km away. This eliminates multiplejourneys along the cable path and dramatically cuts repairand intallation costs.
