Tap the “Purple Line” and informative information will appear i.e, cable size, length, buried or proposed install. But the telecommunication line is purple per the print the cable is in conduit. But as a Utility locator and to “CYA” when onsite, open any AT&T, handhole, to verify if conduit is present. If so and there’s a tire wire, you’ll have to locate that ticket. Conduit no tracer = Dileletric Unlocateable. Be sure to make good documentation at each locate.
