defective. Use the LEDs on the front of each power unit to determine its state.
Table 30 shows the LED and alarm conditions. Ring voltage and neon bus output do not activate alarm

TN760E Tie Trunk Option Settings

The TN760E Tie Trunk circuit pack interfaces between 4 tie trunks and the TDM bus. Two tip and ring
pairs form a 4-wire analog transmission line. An E and M pair are DC signaling leads used for call setup.
The E-lead receives signals from the tie trunk and the M-lead transmits signals to the tie trunk.
