Set TN760E Tie Trunk’s options
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 & 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.
To choose the preferred signaling format (Table 36, Signaling formats for TN760E,
on page 267 and
Table 37, Signaling type summary,
on page 267), set the switches on the TN760E and administer the port
using Figure 50, TN760D Tie Trunk circuit pack (component side),
on page 268 and Table 38, TN760E
option-switch settings and administration, on page 268.
