A Facility Termination Equipment Transmitter Missing alarm occurs when the facility termination
equipment detects an incorrect amount of impedance on its backplane connector. Incorrect impedance is
detected when a transmit cable is missing on the DS-1 port or the backplane does not match the inserted

a DS-3 card.
DS-1s are four-wire circuits and need a positive and negative connection for both transmit and receive.
