TN760E Tie Trunk Circuit Pack Option Settings

Return to Task List
The TN760E Tie Trunk circuit pack interfaces between the tie trunks and the Time Division Multiplex
(TDM) bus. Two tip and ring pairs form a 4-wire analog transmission line. An E and M pair is used for
signaling and 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.
