Option Switch Settings
TN760D Tie Trunk Circuit Pack Option Settings
The TN760D 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.
To choose the preferred signaling format (Signaling Formats for TN760D and Signaling Type Summary), set the switches on the TN760D and administer the port per TN760D Tie Trunk Circuit Pack (Component Side) and TN760D Option Switch Settings and Administration.
