What to do if my DSC Cell Phone is displaying a telephone line trouble condition?

If the control panel of your DSC Cell Phone is displaying a telephone line trouble condition, ensure T1 and R1 of the 3G3070 are wired to the TIP and RING terminals of the control panel. If the 3G3070 is being used as the primary communicator, the yellow light will always be ON. If the 3G3070 red light is FLASHING, refer to the Red Light Status Chart.
